Dissertations / Theses on the topic 'Digital signage'

Digital signage is an emerging new communication technology. It is expected to play an important role in today’s dynamic world as digital signage displays timely information, while reducing the environmental costs associated with traditional printed signage. The main focus of this thesis is the design, implementation, and evaluation of a digital signage system based on a PC to display web contents (or other dynamic information) on digital displays located at one or more locations. The system will display information based upon a “playlist” that can be dynamically updated. It avoids the single point of failure of a television (be it analog or IPTV) based system, since each display has an attached processor and local storage containing both the information to be displayed and the local playlist of what is to be displayed. Additionally, the design allows content to be customized to specific local viewers, i.e., the information displayed can be adapted to the user or users currently in front of the display. The granularity of the schedule (i.e., playlist) is much shorter than in existing digital signage systems – leading to a more visually dynamic experience for viewers. On the basis of our evaluation, we strongly believe that this approach to digital signage will displace existing signage systems.
Digital signage en framväxande ny kommunikationsteknik spelar en viktig roll idagens dynamiska värld. Digital signage visar värdefull och aktuell information förutbildning, näringslivsorganisationer och är viktigt för samhället, eftersom det ger både ettsätt att ge aktuell information och minska de miljömässiga kostnaderna i samband medtraditionella tryckta skyltar. Tyngdpunkten i denna avhandling är att designa, implementeraoch utvärdera en digital signage system baserat på en PC för att visa webb-innehåll (ellerannan dynamisk information) om digitala displayer som finns på en eller flera platser.Systemet kommer att generera värdefull dynamisk information i rätt tid till en grupp avolika tittare. Svarstiden för att visa innehållet på den digitala displayen är mycket snabbjämfört med andra skyltsystem. På grundval av vår utvärdering, tror vi starkt att den kanersätta det finns skyltsystem på marknaden.

Marketing has changed a lot the past decade. New modern marketing channels have been developed and marketing have become more effective. This has affected the expectations advertisers have on advertising channels. One thing advertisers increasingly expect is to be able to efficiently measure the result of advertising, the ROI. A method for measuring ROI of digital signage is in focus in this study. The measurement is enabled by a combination of digital signage and mobile advertising. First a consumer is exposed to digital signage encouraging SMS interaction in order to receive an electronic voucher entitling the consumer to a discount. If the voucher is used, revenues can be linked to a specific campaign and ROI can be calculated. The study focus on measuring the tendency consumers have to interact through SMS when they get exposed to relevant advertising and the tendency they have to use the voucher that is sent to them as a result of the interaction.  The question is how efficient this method is for measuring ROI. In order to bring clarity to the issue, I conducted a quantitative survey using an online self completion questionnaire as measurement tool. It was distributed through e-mail among students at the College of Management at National Taiwan University. Furthermore, I have chosen a deductive approach, my epistemological position is positivism and I therefore utilize the scientific model conducting my research. My ontological position is objectivism meaning that I believe reality is independent of social actors.

The empirical data collected showed that the method in focus have great potential in working efficient for measuring ROI of digital signage. The general tendency to interact through SMS was high, on average 82.3% of the respondents would interact through SMS when getting exposed to relevant advertising. In addition, 96.5% of those would also use the voucher sent to them, enabling ROI calculations.

It was presumed that the digital signage advertising was relevant to such an extent to the consumer getting exposed to it, that he/she already had a purchase intention of the product/service which the advertising regarded. This should be remembered when evaluating the results. Nevertheless, if advertisers succeed in reaching out with relevant advertising enough, the findings in this study indicates that the method is an efficient tool to use for ROI calculations of digital signage.

 

Digital signage är, än så länge, en ung bransch. Det bli dock vanligare och vanligare för företag att använda sig av detta medie för att marknadsföra sig både i och kring den egna butiken. Diskussionen börjar gå mer från att handla om teknik till att handla om innehåll och hur man med hjälp av detta skapar värden. Denna studie syftade till att få en inblick i hur branschen ser ut i dagsläget och hur man tänker kring att skapa ett bra innehåll som är anpassat efter mediet. Resultatet blev en lista av frågor man kan använda sig av i planeringen av en digital signage-lösning.

A Revolução Industrial acabou por constituir uma sociedade de consumo. Essa sociedade utiliza-se da publicidade e da propaganda, dentro do campo da comunicação, como forma de promover o consumo através do contato direto e da orientação do consumidor. A partir do surgimento das tecnologias digitais de comunicação, novas formas de atingir o sujeito contemporâneo vêm surgindo, fazendo com que o campo da comunicação se reoriente. O propósito do presente estudo é apresentar e refletir criticamente sobre o digital signage e suas representações na sociedade do consumo e se essa nova ferramenta de comunicação é eficaz e pode ajudar a manter o propósito da publicidade e propaganda.
The Industrial Revolution turned out to constitute a consumer society. This society uses the publicity and advertising, in the field of communication, as a way to promote consumption through direct contact and customer orientation. From the rise of digital communications technologies, new ways to reach the contemporary subject have emerged, making the field of communication reoriented. The purpose of this study is to present and reflect critically about the digital signage and its representations in the society of consumption and if this new communication tool is effective and can help keep the purpose of publicity and advertising.

The purpose of this thesis is to investigate how Digital Signage systems such as public info kiosks can be designed to better fulfill its main use; to enlighten, encourage and influence the public with information. The challenges presented from earlier studies shows that the public interests and goals, together with proper and relevant content displayed in info kiosks have impact on the attention the public have towards public displays. Qualitative methods such as interviews, usability testing and observations were conducted to further examine how a public info kiosk can be designed to draw attention and grow interest amongst students at K3, Malmo University. Usability testing were used on the digital prototypes that were developed to ensure that the gestural user interface meet the requirements of a proper interaction from the users. Important insights were made concerning; the attention and interest to relevant content, the aspects of the gestural user interface along with the placement of the info kiosk in terms of context. These key factors need to be properly investigated and developed to ensure a better deployment of a public info kiosk. It is suggested that using the principles of interaction design by doing research and studies of public interest and needs, and optimizing it by taking the specific context of place and time in account when a designing content. The results from this thesis suggests that an installation of a public info kiosk will successfully earn the attention and interest from the public if the content is relevant and interesting to the specific public. It is also important that the systems perform well in terms of software and hardware to allow a fluid and intuitive interaction with the gestural user interface.

In this age of ubiquitous advertisement, people are getting more and more burdened withadvertising clutter. Digital Signage (DS) has evolved to be a new medium that can cut throughthis clutter and reach a large number of consumers. Though Digital Signage was introduced asan in-store advertising medium, soon it started to replace traditional static billboards with thebenefit of technological advancement.

While advertising effectiveness is a much discussed subject, effectiveness of an advertisingmedia is still a less explored area. Our research explored the effectiveness of Digital Signageas an advertising media in terms of its placement inside of a store and outside of a store. Atthe beginning we developed a model to measure the effectiveness of Digital Signage on thebasis of an existing model, termed as Advertising Response Model (ARM). Based onprofound study and analysis of previous literature on advertising and media effectiveness,consumer psychology, outdoor advertising and intermediate measurement variables weconstructed the modified version of ARM that deemed to be the best fit with our purpose. Wefurther developed four hypotheses on the basis of the four major variables of our model.

The result of our study indicated that placement of Digital Signage inside and outside of thestore environment impacts the variables of Attention, Recall and Media Liking of theaudience differently. However, no significant difference in consumers’ Buying Interest issupported. Placing Digital Signage inside of the store as well outside of the store both hasdifferent degrees of impact on consumers in terms of Attention, Recall and Media Liking. Thecorrelations among the variables were also explored and thus we presented some strategicinsights about the placement of Digital Signage and practical implications for managers in thescope of our study.

Our research area has received comparatively less academic attention than other advertisingmedia. However, considering the growing importance of Digital Signage as a groundbreakingadvertising medium and scope of future research work, we believe Digital Signage will be asubject of interest for the academics, the advertisers as well as for the companies.

With improvements in power harvesting transducers' power density, and power reduction in communication transceiver systems, displays, sensors and energy-aware microprocessors, smart wireless network nodes are becoming ubiquitous throughout our daily life. Digital signage has gained popularity with the integration of smart wireless network nodes into the application space replacing traditional signage and badges. Primary battery sources traditionally supply energy for digital signage, however, that generates waste and maintenance costs that are counterproductive to using digital signage. Therefore, a digital signage prototype called the wireless display sensor node (WDSN) with a micro-power photovoltaic energy harvesting system was developed at UC Davis and is presented as an alternative in this work. The WDSN and node management system is comprised of an electrophoretic display, Wi-Fi radio, photovoltaic and vibration power transducers, internet connected management system, sensors and power harvesting power electronics. A holistic energy approach was used to drive the development of the proposed digital badge and signage. This approach encompasses the characterization of vibrational and photovoltaic energy sources, analyzing the energy requirement from typical digital signage and developing a power harvesting energy management system that will maximize the lifetime and allow for self sufficiency of the digital signage. To bridge the gap between the energy source and the required peripheral supplies, a multiple input and multiple outputs (MIMO) H-bridge DC to DC converter was designed to harvest and regulate photovoltaic energy, and deliver energy to the various continuously active, and charge-and-execute loads of the WDSN. The H-bridge DC to DC converter comprising of a single inductor, two input power FETs from both primary and secondary power sources, and five symmetric output power FETs to create the various supply rails, supply the regulated energy required for the radio, the display, the sensors and the microcontroller. For the charge-and-execute supplies, a constant current ramp charging was developed to transfer charge at the maximum power point current of the photovoltaic cell to the supply capacitors of the peripherals that support the charge-and-execute supply generation. The MIMO H-bridge DC to DC converter presented supports active regulation using pulse width modulation for high current loads, pulse frequency modulation for light current loads, and ramp charging for capacitive loads. The controller was designed using digital logic and the entire MIMO H-bridge DC to DC converter occupies an area of 0.36 mm2 to 1.63 mm2 depending on the power transistor size selection. The measured instantaneous peak power efficiency is 86% while driving a 63 ?A load with a transient energy efficiency delivered to the load is 81%. The prototype WDSN dissipates 933 mJ to complete a server data synchronization and display refresh. The WDSN update energy when supplied with vibrational and photovoltaic power harvesting is equivalent to 7.52 hours of casual continuous walking (34.44 ?W), 1,230 laboratory door toggles (open and close at 986 ?W) and 12 hours of continuous office lighting (7 am to 7 pm with a daily total of 958 mJ under an average of 538 Lux of CFL lighting).

Den här studiens syfte är att analysera den svenska marknaden för centralstyrda digitala skärmar. Studien görs mot bakgrund av en liknande studie som genomfördes vid Handelshögskolan i Stockholm 2007, som bland annat visade att marknaden inte var mogen för det här mediet. Den här studien ämnar således utreda om man kan dra andra slutsatser om marknaden 2010 och ge förslag på implikationer utifrån nuvarande marknadssituation.

Studien är av kvalitativ karaktär och bygger till stor del på intervjuer med ett antal utvalda leverantörer och köpare av digitala skyltar, som samtliga besitter stor kunskap om produkten och branschen.

Marknaden för digital skyltning har haft en mycket intressant utveckling de senaste åren och växt kraftigt i rådande finanskris. Man kan se en ökad förståelse och kunskap för produkten hos köparna, vilket har lett till att de skillnader som fanns mellan köpare och säljare gällande kunskap om digital skyltning mer eller mindre har försvunnit. Idag bidrar istället köparna i stor omfattning till att skapa framtidens digitala skyltning.

Man kan se hur produkten sträcker sig till allt fler användningsområden och integreras med andra tekniska produkter. Dåtidens teknikfokuserade företag har upplevt en förskjutning från teknikfokusering till marknadsfokusering. Medie- och reklambyråerna börjar få upp ögonen för produkterna på allvar och den mer professionella marknaden har lett till att fler företag väljer att nischa sig och fokusera på sin kärnkompetens för att klara de ökade kraven och konkurrensen.

Studien avslutas med implikationer till såväl teoretiker som praktiker.

Mestrado em Contabilidade Fiscalidade e Finanças Empresariais
No presente trabalho será elaborado e avaliado um projecto de investimento, inserido no mercado publicitário, tendo como base a tecnologia de Digital Signage.O objectivo concreto passa por aferir a viabilidade operacional e económico-financeira da implementação do projecto em Portugal. Para atingir este objectivo com rigor, optou-se por elaborar um business plan onde ficaram sintetizados os aspectos relevantes à implementação e exploração do meio. Todo o trabalho de planeamento e de estruturação do modelo de negócio, serviu também de input e fundamentação para os pressupostos utilizados na avaliação financeira. Deste modo, a ideia de elaboração do presente Trabalho Final de Mestrado passou por articular os objectivos académicos inerentes a um Trabalho de Projecto com o objectivo real de apoiar a decisão de uma equipa de empreendedores, de que o autor do presente documento faz parte, sobre a viabilidade económico-financeira deste projecto de investimento, enquadrado na constituição da empresa Media In. A disposição do trabalho é iniciada com a revisão de literatura onde é analisada a ferramenta business plan, seguida da exposição da metodologia utilizada e por último o business plan do projecto em questão. A análise financeira realizada ao projecto permite concluir que o mesmo é viável uma vez que a sua exploração durante 6 anos, não considerando qualquer perpetuidade, permite obter um VAL de 517,8 mil euros com uma TIR de 58,39% e um payback period de 4 anos. Complementarmente, a análise de sensibilidade permite comprovar a robustez do projecto, identificando-se que os preços de venda dos espaços de publicidade são a variável que mais afecta o VAL: uma variação de +/- 25% dos preços de venda dos espaços de publicidade tem um impacto de +/- 65,28% no VAL. Adicionalmente, a análise de risco também permitiu concluir quanto à robustez dos pressupostos que serviram de base à análise financeira. O exercício da Simulação de Monte Carlo, realizado no ponto da análise de risco (com 10.000 simulações), permitiu obter os seguintes resultados: Média do VAL e da TIR registam variações de -0,13% e -2,35%, respectivamente, face aos valores obtidos no Cenário Base; Não obstante a variabilidade dos resultados, apenas em 15% dos cenários é que se obteve resultados de VAL negativos, demonstrando a grande probabilidade de sucesso do projecto.
In the present work it will be developed and evaluated an investment project, integrated in the advertising market, based on the technology of Digital Signage. The specific objective is to assess the operational feasibility and economic and financial implementation of the project in Portugal. To achieve this accurately, it was decided to develop a business plan in which all relevant aspects to the deployment and exploitation of the business were synthesized. All the planning and structuring work for the business model, also served as a basis for the input assumptions used for financial evaluation. Thus, the idea of drafting this Masters Final Work went through articulate both the academic goals inherent to a Project Work and the real objective of supporting the decision to a team of entrepreneurs, which the author of this document belongs, on the economic and financial viability of this investment project, framed in the constitution of the company Media In. The layout of the work is initiated with the review of the literature about the business plan tool, followed by exposure of the methodology used and finally the business plan of the project in question. The financial analysis of the project allows us to conclude that it is feasible for the evaluation period of six years, not considering any perpetuity, and gives a NPV of EUR 517,800 with an IRR of 58.39% and a payback period of 4 years. In addition, sensitivity analysis allows to prove the robustness of the project, identifying the selling prices of the advertising space as the variable that most affects the NPV: a variation of +/- 25% of the selling prices of the advertising space has an impact of +/- 65.28% in NPV. Additionally, risk analysis also concluded about the high robustness of the assumptions that were the basis for financial analysis. The exercise of Monte Carlo simulation performed at the point of risk analysis (with 10,000 simulations) obtained the following results: Average NPV and IRR register changes of -0.13% and -2.35% respectively compared to values obtained in Base Scenario; Despite the variability of results, only 15% of the scenarios obtained had negative NPV, demonstrating the high probability of success of the project.

The Portuguese software company Viatecla is planning to launch this product initially in the Portuguese tourism sector with the focus on Travel agencies. This plan serves as a basis for a discussion.

Gustaf Fröding hotell behöver en smidigare lösning för att uppdatera och visa information om konferensbokning. De använder sig idag papperskyltar för att informera och vägleda kunder till konferensrummen. Pappersskyltarna ska ersättas med surfplattor för att bland annat ge bättre intryck på deras kunder. Surfplattorna behöver en applikation för att ta emot och visa materialet. Vi utvecklade en prototyp för detta ändamål som sedan ska användas för vidareutveckling av systemet. Denna uppsats beskriver vår utveckling av denna applikation. Resultatet blev en webbapplikation skriven i ASP.NET MVC som är baserad på Gustaf Fröding hotells behov. Webbapplikationen har administrativa funktioner för sammansättning av media, vilket skapar presentationer. Surfplattor kopplar upp sig till webbapplikationen via en unik URL som visar tilldelad presentation. Applikationen levererades och beslutet om vidareutveckling är ännu inte bestämt.
Gustaf Fröding hotel needs a smother agile solution for updating and displaying the information on conference booking. They currently use paper signs to inform and guide customers to the conference rooms. These paper signs are going to be replaced by tablets to create a better impression for their customers. The tablets need an application for receiving and displaying material and we developed a prototype for this purpose. This prototype will be used for further development of the system. This dissertation describes our development of this application. The result of the project is a web application written in ASP.NET MVC based on Gustaf Fröding hotels requirements. The web application has administrative functions for the composition of media, creating presentations. Tablets connect to the web application via a unique URL that displays the assigned presentation. The application was delivered but the decision of further development has not yet been made.

Public areas are more and more equipped with digital screens that are used to inform or promote a particular product. This is a way to communicate with the people on that area. The idea is to get people's attention, make them read and take in information and possibly buy the product that is marketed. This type of digital display is called digital signage and can also be used as an information channel of a company where information directed to employees and visitors is displayed. CGI Östersund has a screen placed in their office that works as such an information channel. This thesis is about investigating and analyzing the current presentation and creating a new solution with a custom interface that will be more effective and engage more people. The new solution is interactive and clickable with the help of a mouse. A user study has been done using a Kinect sensor to see how many people are watching the screen, how long they look at the screen and from what distance. This data was also supplemented by a survey sent to the employees at CGI Östersund. The result of the user study shows that there was no significant difference between the previous solution and the new one. This may be due to two main reasons: the lack of time in which the experiment was performed and the location of the digital screen that is not currently optimal.

The number of connected devices is rapidly growing. MNOs (Mobile Network Operators) work hard to offer their customers the latest technologies, and due to this it has become increasingly important to understand how new technologies can be leveraged and positioned in existing markets. This master thesis, made on behalf of the Swedish company Ericsson AB, is an evaluation of a new cellular technology called LTE-Broadcast. Since LTE-Broadcast is a very new technology, it is not certain how it should be positioned towards competing technologies such as 3G, Wi-Fi or fiber connections. The general aim of this thesis was to assess whether or not there are needs in the digital signage market that could be satisfied by the benefits of the LTE-Broadcast technology. The global digital signage market was used to collect quantitative data and the Swedish market was used to collect qualitative data to gain a deeper understanding of the digital signage actors and their needs. In total there wereeleven interviews conducted with selected actors from the value constellation. The most important results were found in the Swedish market, showing that almost every actor has experienced some issues with current media delivery systems. Their main issues include low bandwidth, bad cellular reception or unstable connections, high maintenance costs, high costs of data and time consuming cable installations. The analysis and discussion suggests that several of the issues could be solved by LTE-Broadcast. The increased QoS and guaranteed media delivery should be appreciated by a majority of the actors, while the ability to live stream content are sought after by some of the actors. The Porter’s five forces analysis has shown that the main threat to market adoption is the threat of substitute products such as fiber or Wi-Fi. This threat could however be averted by marketing LTE-Broadcast on verticals where the substitutes are unavailable, such as in the transportation and public transport vertical. To conclude, LTE-Broadcast has been shown to be a good fit for certain parts of the digital signage value constellation.

Antalet uppkopplade enheter växer kraftigt. Täckningen på mobilnät med hög bandbredd utökas ochmobiloperatörer jobbar ständigt för att erbjuda sina kunder den senaste tekniken. På grund av detta har det blivit viktigare och viktigare att förstå hur nya teknologier kan positioneras på nuvarande marknader. Detta examensarbete, gjort på uppdrag av Ericsson AB, är en utvärdering av en ny mobilteknik kallad LTE-Broadcast. Eftersom LTE-Broadcast är en väldigt ny teknologi är det oklart hur tekniken ska positioneras i förhållande till konkurrerande teknologier såsom 3G, Wi-Fi och fiberuppkopplingar. Den övergripande målsättningen med denna uppsats har varit att undersöka huruvida det finns behov i digital signage-marknaden som skulle kunna tillgodoses av LTE-Broadcast-teknologin. Den globala digital signage-marknaden har använts för att samla in kvantitativ data och den svenska marknadenhar använts för att samla in kvalitativ data och för att få en djupare förståelse för digital signage-aktörerna och deras behov. Totalt genomfördes elva intervjuer med utvalda aktörer på marknaden. De viktigaste resultaten upptäcktes på den svenska marknaden, där det visade sig att nästan varje aktör har upplevt problem med nuvarande teknik. Deras huvudsakliga problem inkluderar otillräcklig bandbredd, dålig mottagning eller instabila uppkopplingar, höga kostnader för underhåll och tidskrävande kabelinstallationer. Analysen och diskussionen pekar på att flertalet av digital signage-aktörerernas upplevda problem skulle kunna lösas med LTE-Broadcast. Ökad QoS och garanterad leverans av innehåll borde uppskattas av en majoritet av aktörerna, medan möjligheten att live-sända innehåll borde uppskattas av några aktörer. Porters femkraftsmodell har visat att det största hotet mot ett införande av LTE-Broadcast är konkurrerande tekniker såsom fiber och Wi-Fi. Detta hot kan dock undvikas genom att marknadsföra LTE-Broadcast mot marknader där konkurrerande teknologier inte finns tillgängliga, såsom t.ex. transport- och kolletivtrafikindistrin. Sammanfattningsvis har LTE-Broadcast visat sig passa bra in i enskilda delar av digital signage-värdekedjan.

With a growing number of connected devices and an increased market penetration for wireless and cellular technologies, it has become more and more important to understand how new technologies can be leveraged in existing markets to further understand their overall impact on society as a whole. This master thesis aims to investigate potential business opportunities for a new communications technology within an existing market. This new technology, known as LTE-Broadcast, is an evolution of cellular 4G technologies, which allows content to be broadcasted throughout a cellular network. The thesis focuses on the digital signage market and uses it as context in which to investigate potential business opportunities. Digital signage, in short, refers to the use of digital screens as a medium for communication. This thesis therefore intends to understand how LTE-Broadcast can be leveraged as a viable business option within the digital signage market by perusing both a global and national perspective of the market. By investigating and analyzing a global perspective and a national perspective, in the form of the Swedish digital signage market, a clear picture of the value LTE-Broadcast can generate within digital signage is achieved. This, consequently, allows for the identification and conceptualizing of a viable business model for Mobile Network Operators (MNOs) while leveraging LTE-Broadcast in the digital signage market. The research, conclusively, allows for a clear understanding of the model’s scalability. Ultimately, the understanding of the technology’s viability within a given market will influence its successful adoption in society and its potential utilization by MNOs to create a sustainable competitive advantage within the digital signage market.

Till följd av de stora miljöutmaningar som världen står inför idag, där majoriteten av dem orsakats av människan, har ett hållbart konsumtionsbeteende blivit alltmer betydelsefullt. För att uppnå ett hållbart konsumtionsbeteende bör butikers gemensamma mål vara att involvera kunder till att handla mer hållbart samt främja miljövänliga och hållbara produkter. Tidigare forskning indikerar att konsumenter ofta vill konsumera mer hållbart men misslyckas emellanåt att konsumera efter sina värderingar, bland annat på grund av bristande information eller av ouppmärksamhet. Digitala skärmar kan anses vara ett fördelaktigt marknadsföringsverktyg för att främja hållbar konsumtion då det engagerar flera mänskliga sinnen samt tillkallar uppmärksamhet hos kunden. Syftet med studien är att empiriskt undersöka hur olika innehåll på en digital skärm kan påverka försäljningen av en specifik marknadsförd ”hållbar” respektive ”icke-hållbar” produkt. För att besvara syftet genomfördes ett fältexperiment på två likvärdiga avfallspåsar i en stormarknad där ena alternativet var ”hållbart” och det andra ”icke-hållbart”. Vidareplacerades en digital skärm ovanför de båda alternativen med ett affektivt innehåll under ena veckan och ett socialt validerande innehåll under den andra veckan. Studien utgick från en kvantitativ forskningsstrategi där resultaten baserades på försäljningsdata framtagen från de olika försäljningsplatserna. Studien indikerar att innehållen på den digitala skärmen inte påverkade kunders beslut vidvalet mellan den ”hållbara” och den ”icke-hållbara” avfallspåsen, då försäljningen av den ”icke-hållbara” avfallspåsen genomgående såldes mer än den ”hållbara”. I stället för att kunderna blev påverkade av hållbarhetsaspekten som förmedlades via skärmen kan det antas att andra faktorer såsom vanor och rutiner samt placering i butiken hade en störrepåverkan på kundernas beslut. Vidare framkommer vikten av butikernas inflytande vid kunders konsumtion, både med vilka varor de väljer att exponera och marknadsföra samt hur de väljer att bemöta kunden både verbalt och via skyltning.
As a result of the major environmental challenges facing the world today, where the majority of these have been caused by humans, sustainable consumption behavior has become increasingly important. To achieve sustainable consumption behavior, the common goal of stores should be to involve customers in more sustainable shopping behavior and to promote environmentally friendly and sustainable products. Previous research indicates that customers often want to consume more sustainably but sometimes fail to consume according to their values, among other things due to lack of information or inattention. Digital screens can be considered as a beneficial marketing tool to promote sustainable consumption as it engages several human senses and attracts customer attention. The purpose of the study is to empirically investigate how different content on a digital screen can affect the sales of a specific marketed sustainable and non-sustainable product. To answer the purpose, a field experiment was carried out on two equivalent waste bags in a supermarket where one alternative was sustainable and the other non-sustainable. Furthermore, a digital screen was placed above the two alternatives with an affective content for one week, and socially validating content during the second week. The study was based on a quantitative research strategy where the results were based on sales data produced from the various points of sale. The study indicates that the contents of the digital screen did not influence customers' decisions in the choice between the sustainable and the non-sustainable waste bag, as sales of the non-sustainable waste bag were consistently sold more than the sustainable one. Instead of the customers being influenced by the sustainability aspect that was conveyed via the screen, it can be assumed that other factors such as habits and routines as well as locations in the store had a greater impact on the customers' decisions. Furthermore, the importance of the stores 'influence on customers' consumption emerges, both in which goods they choose to expose and market and how they choose to respond to customers both verbally and via signage.

This study aims to evaluate the altimetric accuracy of Digital Surface Models - DSM and generation of a DSM composed using scene taken by PRISM Sensor - Panchromatic Remote Sensing Instrument for Stereo Mapping (viewing directions Backward, Forward and Nadir) which is located aboard the ALOS satellite (Advanced Land Observing Satellite). The Toutin Model is used to perform on the realization of geometric correction of images, were that took into account the influence of the number of control points and tie points for generation of DSMs. There were generated 54 models divided into four tests which look forward to determinate the minimum number of tie points to be used for the generation of DSM (test 01), the adequacy of the methodology proposed by IBGE (2009) for the region studied, whose relief has different characteristics employed by this agency (test 02), the influence of increasing the number of control points on the altimetric quality DSMs (test 03) and the effect of the combination of the three viewing directions behavior and the use of different strategies of correlation between images and spatial resolution of the models in the final products accuracy (test 04). The DSM derived from each test were evaluated by use of the Decree-Law 89.817/1984 and those which recieved better ratings were submitted to a local analysis, where it was investigated the behavior of the altitude values using the PEC for an area located in Viçosa and a empirical analysis was employed, in order to verify the behavior of pixels located regions that had shades of vegetation and cloud shadows using for that the correlation coefficient of epipolar pairs generated for each DSM besides conducting analysis of the effects of slope on the quality altimetric using as base the correlation coefficient. The DSMs that showed better results after the use of all these tests were used for the orthorectification of the Nadir scene and orthoimages, were evaluated globally using the PEC and the local way, in order to verify the influence of radiometric resolution on the vectorization of orthoimage. The DSM used for orthorectification also underwent a final examination, which took place a refinement in their altitude values by employing the Koppe s Formula modified by Kraus (2004) that takes into account the influence of slope and the scale factor when taken on the scenes of aerial images which led to a Composed DSM consisted of all pixels that presented a lower standard deviation. The results revealed that the PRISM sensor allows to obtain DSMs of consistent standards for the National Mapping Scale 1:25.000, with the need to use a minimum number of seven control points associated with twelve tie points and use of viewing directions Backward x Nadir for the generation of models. The increase in the number of control points to perform the correction using the geometric Toutin model did not bring significant improvements to the quality of altimetric DSMs evaluated, although they showed the best results were those that used 60 control points in their generation. The methodology proposed by IBGE (2009) proved to be applicable to regions with similar characteristics to those studied in this work, although there is a need for testing in areas with similar characteristics studied. Using the Koppe s Formula modified was satisfactory, allowing to associate in a single DSM the lowest indicative altimetric errors found for the altimetric component, and the results were superior to the other models evaluated. The orthoimages obtained are classified in Class A of the Decree-Law for the scale of 1:25.000, however due to the low radiometric resolution of the scenes PRISM (8 bits) the extraction process of physical elements, especially in urban areas, become difficult to interpret.
O presente trabalho tem como objetivo a avaliação da acurácia altimétrica de Modelos Digitais de Superfície (MDSs) e geração de MDSs compostos, utilizando a cena tomada pelo Sensor PRISM - Panchromatic Remote Sensing Instrument for Stereo Mapping no modo triplet (visadas Backward, Nadir e Forward) que se encontra a bordo do Satélite ALOS (Advanced Land Observing Satellite). Para realização da Correção Geométrica das imagens foi empregado o Modelo de Toutin. Foram gerados 54 MDSs divididos em quatro testes, que procuraram verificar o número mínimo de pontos de ligação a serem utilizados para geração de cada MDS, a adequação da Metodologia proposta por IBGE (2009) a uma região, cujo relevo possui características diferentes da estudada por este órgão, a influência do aumento do número de pontos de controle na qualidade altimétrica dos MDSs e a combinação das três visadas associadas ao uso de diferentes estratégias de correlação entre imagens e resolução espacial dos modelos. Os MDSs resultantes de cada teste foram avaliados através do emprego do Decreto-Lei 89.817/1984 que institui o Padrão de Exatidão Cartográfica PEC e aqueles que obtiveram melhor classificação foram submetidos a uma análise local, onde se verificou o comportamento dos valores de altitude empregando o PEC para uma área situada no município de Viçosa, bem como realizada uma análise empírica, com a finalidade de verificar o comportamento dos pixels situados em regiões que apresentavam sombras da vegetação e sombras de nuvens, utilizando para isso, o coeficiente de correlação dos pares epipolares gerados para cada MDS, além da realização de análise dos efeitos da inclinação do terreno sobre a qualidade altimétrica tomando como base o coeficiente de correlação. Os MDSs que apresentaram melhores resultados após emprego dos quatro testes foram utilizados para a ortorretificação da cena Nadir e as Ortoimagens resultantes foram avaliadas de maneira global empregando o PEC e de maneira local, onde verifIcou-se a influência da resolução radiométrica na vetorização da Ortoimagem. A última análise consistiu na realização de um refinamento nos valores de altitude dos MDSs que apresentaram melhor classificação, através do emprego da Fórmula de Koppe modificada por Kraus (2004), que leva em consideração a influência da declividade e do fator de Escala sobre as cenas quando tomadas de imagens aéreas. Esta Fórmula foi adaptada para uso em uma imagem orbital e utilizada no intuito de se obter um indicativo da localização do erro altimétrico sobre cada MDS, onde se gerou um novo modelo, denominado MDS Composto. Os resultados obtidos permitiram constatar que o sensor PRISM permite a obtenção de MDSs compatíveis as normas da Cartografia Nacional para a Escala de 1:25.000, havendo a necessidade de utilização de um número mínimo de sete pontos de controle associados a doze pontos de ligação e o uso das visadas Backward x Nadir (que apresentaram os melhores resultados) para a geração dos Modelos. O aumento do número de pontos controle para realização da correção geométrica empregando o Modelo de Toutin não trouxe melhorias significativas aos MDSs avaliados, embora os que apresentaram melhores resultados foram aqueles que utilizaram 60 pontos de controle em sua geração. A Metodologia proposta por IBGE (2009) se mostrou aplicável a regiões com características semelhantes à estudada neste trabalho, embora exista a necessidade de realização de testes em áreas com características semelhantes à estudada. O uso da Fórmula de Koppe modificada se mostrou satisfatório, permitindo associar em um único MDS os valores de altitude que apresentam o menor indicativo de erro encontrado para a componente altimétrica, sendo que os resultados obtidos através do emprego desta Equação foram superiores aos demais Modelos avaliados. As ortoimagens obtidas se enquadraram na Classe A do PEC para a escala de 1:25.000, contudo devido à baixa resolução radiométrica das cenas PRISM (8 bits) o processo de extração de elementos físicos, principalmente em áreas urbanas tornaram-se de difícil interpretação.

The use of large displays for digital signage in collective spaces is increasing for numerous purposes. For most signalling scenarios, the dynamic adjustment of the display contents is desirable. Contextual information related to the site and to the signalling profile of observers may be taken into consideration for the selection of content and for user interaction. Interactions can occur implicitly and transparently, by just mutually identifying users and systems for the selection of the content displayed, or by allowing the explicit data exchange between users and the signalling system. Mobile computing devices and wireless technologies extend the possibilities of interaction with users, creating a complex scenario for the exhibition of public and private data. The dynamic analysis of contextual information, the retrieval and generation of presentation data, and the interaction with users all require significant processing which demonstrate the complexity of encoding a digital signage system. This thesis presents a distributed system and service-based software architecture developed for creating interactive digital signage systems. The architecture allows the centralized, but scalable, creation and management of digital signage systems containing different displays and users. An implementation of the proposed architectural model and software was carried out and the results show its ability to serve the creation of dynamic, flexible and interactive digital signage systems.
O uso de monitores de vídeo como forma de sinalização e apresentação de conteúdos digitais em ambientes de uso coletivo é crescente, com inúmeras finalidades. Além disso, para a maior parte dos cenários de sinalização, o ajuste dinâmico dos conteúdos a apresentar é algo desejável. Informações contextuais, relacionadas ao local de sinalização e ao perfil dos observadores, podem ser levadas em consideração para a seleção de conteúdos e para a interação com usuários. Interações podem ocorrer de forma implícita e transparente, apenas identificando usuários e sistemas mutuamente para a seleção do conteúdo exibido, ou permitindo a troca de dados explícita entre os usuários e o sistema de sinalização. Dispositivos computacionais móveis e tecnologias de comunicação sem fio ampliam as possibilidades de interação com usuários, criando um cenário complexo para exibição de dados públicos e privados. A análise dinâmica de parâmetros de contexto, a obtenção e a geração de conteúdos e a interação com usuários, contudo, requerem processamentos que evidenciam a complexidade da codificação de sistemas de sinalização digital. Este trabalho apresenta uma arquitetura de sistema distribuído e de software baseado em serviços, desenvolvida para a criação de sistemas de sinalização digital interativa. A arquitetura permite a criação e o gerenciamento centralizado, mas escalável, de sistemas de sinalização digital contendo diferentes pontos de apresentação e conjuntos de usuários. Uma implementação do modelo arquitetural e de software proposto foi realizada e os resultados mostram sua capacidade de atender à criação de sistemas de sinalização digital dinâmicos, flexíveis e interativos.

A Sinalização Digital consiste na transmissão de conteúdo via mídia digital, sendo normalmente utilizada por meio de painéis informativos dispostos em locais públicos para despertar a atenção dos espectadores. A pesquisa descrita nesta dissertação, consistiu em criar um aparato para exibição de vídeos e gravação do ambiente, análise e modelagem da atenção dos espectadores quanto à exibição de vídeos em um cenário de sinalização digital. No estudo, foram utilizadas ferramentas de visão computacional para categorizar os espectadores por gênero e faixa etária. A partir do registro dos anúncios exibidos e da classificação dos espectadores foram automaticamente construídas Redes Bayesianas, as quais representaram corretamente o perfil dos espectadores com área sob a ROC de 0,82. Durante a realização da pesquisa,foram evidenciadas lacunas na validação de classificadores de idade utilizando imagens de faces. Para tratar tais lacunas,uma abordagem de estratificação de faixas etárias foi proposta para treinar uma rede neural que obteve desempenho superior ao estado da arte,que foi de 72% quando validado na base de faces MORPH. Para que fosse possível realizar esta pesquisa, devido à inexistência de uma base de vídeos disponível publicamente com rótulos categorizando seus conteúdos, foi criada uma base de vídeos contendo 152 vídeos rotulados manualmente em seis categorias. As análises dos vídeos dos espectadores utilizando as imagens de suas faces e a classificação de tais imagens em relação ao gênero e a idade indicou que indivíduos pertencentes a categorias diferentes dedicam diferentes graus de atenção a vídeos diferentes. Assim, o sistema desenvolvido pode ser utilizado na categorização dos espectadores, para exibição de anúncios de forma automática como forma de auxílio na alocação do tempo de exibição das empresas anunciantes, dentre outras aplicações.

The research described in this dissertation, consists in creating a method for video display, environment recording, and attention modeling in video display for digital signage scenarios. In this study, computer vision tools were used to categorize audience by gender and age group. Bayesian Networks were automatically builtusing there cords obtained from transmittedads, in which the correct audience profile representation had area under the curve (AUC) of 0.82. When performing this research, it were observed gaps in validation of age classifiers using faces. To address these deficiencies, an age stratification approach was proposed to train a neural network that achieved superior performance in comparison with the state of the art which was 72% when validated on the MORPH face dataset. To make it possible to carry out this research, due to the lack of a publicy available dataset of labeled videos, a video dataset was created containing 152 videos manually labeled in six categories. The analysis of the faces of the viewer and the classification of such images with respect to gender and age indicated that the individuals belong to different categories that dedicated varying degrees of attention todifferentvideos. Thus,thesystemdevelopedcanbeusedinthecategorizationofthespectators, for automatically transmitted advertisements as a way to aid in the allocation of time for the transmission of advertising companies, among other applications.

Forskning visar att 65 procent av konsumenternas köpbeslut av dagligvaror fattas i butikerna. Denna studie syftade till att studera konsumenters medvetenhet om tv-reklam i dagligvarubutik, hur deras köpbeteende påverkas, och i vilken grad kognitiva och perceptuella faktorer inverkar på om tv-reklam medvetet uppfattas av konsumenten eller inte. Endast fyra av 120 konsumenter upptäckte den tv-skärm som de stått intill och ingen mindes vad tv-skärmen visat, en stark indikation på att konsumentens uppmärksamhet kan vara mycket svårfångad. Huruvida visad reklamfilm var försedd med ljud och prisuppgift eller inte tycktes inte ha någon effekt på konsumenternas medvetenhet och ingen försäljningseffekt kunde påvisas men generella slutsatser kräver ytterligare forskning. Fortsatt forskning kan även undersöka konsumentens mottaglighet för tv-reklam på olika platser i butiken.

A fast-digitizer data acquisition system recently installed at the neutron time-of-flight experiment nELBE, which is located at the superconducting electron accelerator ELBE of Forschungszentrum Dresden-Rossendorf, is tested with two different detector types. Preamplifier signals from a high-purity germanium detector are digitized, stored and finally processed. For a precise determination of the energy of the detected radiation, the moving-window deconvolution algorithm is used to compensate the ballistic deficit and different shaping algorithms are applied. The energy resolution is determined in an experiment with γ-rays from a 22Na source and is compared to the energy resolution achieved with analogously processed signals. On the other hand, signals from the photomultipliers of barium fluoride and plastic scintillation detectors are digitized. These signals have risetimes of a few nanoseconds only. The moment of interaction of the radiation with the detector is determined by methods of digital signal processing. Therefore, different timing algorithms are implemented and tested with data from an experiment at nELBE. The time resolutions achieved with these algorithms are compared to each other as well as to reference values coming from analog signal processing. In addition to these experiments, some properties of the digitizing hardware are measured and a program for the analysis of stored, digitized data is developed. The analysis of the signals shows that the energy resolution achieved with the 10-bit digitizer system used here is not competitive to a 14-bit peak-sensing ADC, although the ballistic deficit can be fully corrected. However, digital methods give better result in sub-ns timing than analog signal processing.

Denna studie syftar till att förse kommuner och fackmän med en rimlig utgångspunkt vid upprättande av ljusemitterande skyltar i stadsmiljö och på så vis bidra till perceptuellt väl sammansatta stadsrum. De vägledande frågeställningar som tas upp i rapporten ser till såväl lämpliga kontrastförhållanden som digitala skyltars påverkan på rumsupplevelsen. Med grund i vetenskapsteori rörande seende, rumslig upplevelse och digitala skyltar upprättades en 20 kvadratmeter stor digital skylt på Tändstickstorget i Jönköping, vari ett fältexperiment kom att äga rum den 15 mars 2017. Under experimentet kom skylten att ställas till sex olika scenarier med avseende på skyltluminans och kontrastförhållande till dess direkta omgivning, vilka samtliga granskades av en respondentgrupp om 20 personer. Därefter följde en omfattande visuell utvärdering av den digitala skyltens perceptuella påverkan på det aktuella torgrummet, med skylten inställd på det scenario som dömts behagligast. Av resultaten framgår att ett lågt kontrastförhållande mellan den ljusemitterande skylten och dess direkta omgivning föredras framför ett högt, då en tydlig korrelation mellan höga kontraster och obehag identifierats. Vidare visar resultaten att en digital skylt leder till att stadsrummet som helhet upplevs mörkare och att dess upplevda form och storlek förändras. Konkurrens uppstår mellan lokala landmärken och skylten, då dess luminanta yta blir det dominerande objektet i synfältet. Det framgår tydligt av undersökningen att beslut vid implementering av digitala skyltar i stadsmiljö bör styrkas med en god kunskapsgrund, något som resultaten och det specifikt för studien utformade mätdataformuläret avser bidra till.
This thesis aims to provide municipalities and professionals with a reasonable starting point when planning for light emitting signs in urban environments, thus contributing to perceptually cohesive urban spaces. The questions raised in this report examine appropriate contrast ratios as well as digital signage’s impact on the spatial experience. Based on scientific theory concerning human vision, spatial experience and digital signage’s a 20-square meter digital sign was installed at Tändstickstorget in Jönköping, where a field experiment took place on the 15th of March 2017. The sign was programmed into six different scenarios with regard to its screen luminance and contrast ratio to its immediate surroundings, all of which were reviewed by 20 respondents. Furthermore, an extensive visual evaluation was carried out to investigate the perceptual impact the digital sign had on the city square, with the sign set to the scenario deemed most pleasant. The results show that a low contrast ratio between the light emitting sign and its immediate surroundings is preferred to a high ratio, seeing as a clear correlation between high contrasts and discomfort has been identified. Moreover, the results show that a digital sign makes the urban space perceptually darker overall, whilst at the same time affecting the form and size of the space. Competition arises between the local landmarks and the sign, as its luminous surface becomes the dominant object in the field of view. It is clear from the study that decisions regarding the implementation of digital signs in urban environments should be strengthened with a good knowledgebase, which the results along with the measurement data form developed specifically for the study intends to contribute with.

Few Engineering students at Uppsala University choose to pursue their studies in signal processing, due to the level of difficulty within the subject. The main underlying problem is the students' trouble with understanding the behaviour of analog and digital filters, as well as the concept of stability. In this project, a system that allows the teacher to visualize multiple concepts in signal processing was developed. The system consists of analog filters, digital filters implemented in a digital signal processor, and software for simulating unstable filters. The goal with this project is to give teachers the possibility to make students intuitively understand the subject, and improve the overall learning experience for the students.
Många ingenjörsstudenter vid Uppsala Universitet väljer att inte fortsätta sin studier inom signalbehandling, på grund av ämnets höga svårighetsgraden. Den största faktorn är studenters problem med förståelse för analoga och digitala filter, samt filter instabilitet. Det här projektet strävar efter att skapa ökad förståelse hos studenter inom ämnet genom att tillhandahålla ett verktyg för lärare att på ett intuitivt sätt visualisera signalers beteende för sina studenter. Det färdiga verktyget består av analoga filter, digitala filter implementerade i ett inbyggt system och mjukvara för att simulera instabila filter.

Embedded systems are applied in many fields and play significant roles in our daily lives. In the past, there are no any functions can be applied in networking and configuration interface within embedded system. Therefore, the application range is very limited. Since the Embedded Linux becomes very popular, the embedded systems functions will be more expected and more easily used. The goal of this study is to develop an ARMLinux embedded system development platform to provide the functions of Digital Signage Application and configuration interface and to be used for the consideration of SoC contents integration. To use this facility, which the development platform provides, the embedded device can be connected to the uCLinux functions of multi threads control and configuration setup. To verify the validation of development platform, we adopt open source method to implement a low-cost and high-performance system. User can run Digital Signage Player at anywhere and get more lower cost to use Digital Signage player.

Abstract This study attempts to investigate the factors affecting the advertising effect of Digital signage. The main ideas of this paper are from findings of Rui Yuan Li, Raymond, Kelsen, OVAB etc. Based on the above literature review, we summarized five dimensions such as contents, environment, cost considerations, update rate and average unit audience. The methodology of AHP (Analytic Hierarchy Process) developed by Thomas L. Saaty will be used as the theoretical framework and research design. Based on the important factors which were obtained from the past research, an expert forum and expert questionnaires were conducted to analyze the affecting factors of Digital Signage advertising effect. This study will use AHP method to investigate the ranking and weights factor of Digital Signage advertising effectiveness. The purposes of this study are as follows: (1) to analyze the factors of Digital Signage advertising effectiveness. (2) to classify the factors of Digital Signage advertising effectiveness. (3) to use AHP for Ranking and weights of the factors of Digital Signage advertising effectiveness. The results show that the weight of Digital Signage advertising effectiveness as follow: Average unit audience (34.42%), Contents(23.36%), Environment(18.33%), Cost considerations(16.29), and Update rate(7.6%). The first six factors of Digital Signage advertising effectiveness as follows: Crowds amount, Dwell time, Traffic flow, Rotation time, Content relevancy and Stability equipment. The finding of this study reveals that Average unit audience level is extremely important for Crowds amount, Dwell time and Rotation time. Accordingly, the average unit audience will be used instead of Crowd amount to measure the advertising effectiveness. Secondly, the Line planning is more important than Screen size. Finally, the Content relevance and Interactive content are more important than Content types. In practice, this study also found that Digital Signage advertising is moving from the previous OTS (Opportunity To See) to OTR (Opportunity To Reach) and the new media will provide customer touching experience.

The electronic display device used in the digital signage is now constantly developing and progressing. Consumers started to demand for displaying on large screen increasingly, and the required size of signage is usually much larger than the size used in the market recently. Therefore, the need of tiled screen emerges. In this study, we adopt the design of using software and hardware together to produce a system of tiled digital signage. We make a connection to client Android media player on embedded platform, and cut broadcast video to transmit it to fast interpolator on FPGA platform through media content management of cloud-computing digital signage. Each interpolator enlarges the image of the cut video and shows it on independent LCD to complete LCD tiled display. Finally, we accomplished the integration of software and hardware of digital signage. We also found that the display of VGA can reach to 16.2 Frames/sec. In this study, the method and system structure we proposed can decrease the costs of LCD tiled system and enhance the quality of displaying tiled image.

The enterprises are seeking for profit growth, but the life cycle of enterprises is decreasing, they must keep innovating to remain competitive in the industry. When a company pursuit growth, it develops a good set of business model, but as the product gets mature, and the innovative efficiency drops, the company’s growth would slow down, then it must face the gap of reduction and create new value. When a company is using a new service, facing new customers, or reaching to a new market, it must clarify the existing business model and create new operational theory, which is the business model innovation. Business model innovation has been studied and analyzed by many experts, and there are many models and structures that lead business to success, this article will study these theories and make connection to the current industry businesses.

Advertisement constantly penetrates everyone’s life through all kinds of media exposure. The general public becomes accustomed to most of the existing types of advertisement, but these existing types of advertisement did not arouse the interest of the public because it is shown by 2D electrical billboard and lacks of innovation and creativity. There is no motivation to watch the content of advertisement. The cost of the 3D digital signage equipment is high, and the pixels are easily misplaced, including failed to present delicacy of the words due to resolution downgrade. However, with the advance of display technology, there are many factors of new technology that can be applied into industry of advertisement. We combined a new application of 2D-3D hybrid outdoor advertising billboard. The 3D digital signage of the new application of 2D-3D hybrid outdoor billboard is expected firstly to draw attention of the public with product pictures presenting by 3D technology and moreover encourage the public to watch the 2D advertisement as assistant description. This combination presents an more exquisite advertisement with words In order to better the design parameters of this system, this thesis explores the new application of 2D-3D hybrid outdoor billboard from six experiments based on human behavior. The six experiments are as followed: First, the 3D effect of the new application of 2D-3D hybrid outdoor advertising billboards: To verify the new 2D-3D hybrid outdoor billboards have 3D effect is the first step; otherwise, the advantage of this new type of advertising billboards will lose its advantage. Secondly, the best 3D / 2D screen area ratio of the new 2D-3D hybrid outdoor billboards: Continuously adjust 2D screen space from the projector to find out the parameters for the best outdoor billboards 3D / 2D screen area ratio. Thirdly, integrate Transferred-reflected Mirror into new 2D-3D hybrid outdoor billboards: see if the 3D stereo effect could be enhanced by integrated Transferred-reflected Mirror into the new 2D-3D hybrid outdoor billboards as a result of its characteristic that reflects the environment Fourth, the best distance ratio of the reflector in the new 2D-3D hybrid outdoor billboards: constantly adjusting reflector location in the scrolling text to find the best 3D effect of the reflector distance ratio. Fifth, to find the best brightness ratio of the reflector in the new 2D-3D outdoor billboards: Adjust the brightness of the reflector to find the brightness ratio of the best 3D effects reflector. Sixth, increase display board into the new application of 2D-3D hybrid outdoor billboards: to place a display board in front of the new 2D-3D hybrid outdoor billboards to see if this action could the depth feeling of 3D image. The result of this experiment is that the new application of 2D-3D hybrid outdoor advertising billboard actually has 3D stereo effect which is 16% higher than original single 3D digital signage. Through the experiment focused on human behavior, it is concluded that transferred-reflected mirror and the display board could enhance 3D stereo effect by 16% ~33% and when the best parameters for the transferred-reflected mirror and the display board are added into the new 2D-3D hybrid outdoor advertising billboard, it can enhance human’s feelings of depth under the circumstance without increasing the disparity from the pictures of left eye and right eye.

The network technology is getting more and more advanced, and it has created a change in the retail business model, and people’s consumption habits have also changed. Therefore, the shopping malls have been transformed one after another. They increase the service items that the online e-commerce can’t replace to attract the consumers to go to consumption in the shopping centers. In addition to developing the business outward, the emphasis on the experience of the customers is also an important element that affects turnover. In recent years, the development of technology, the increase in network speed and the popularity of digital signage have reduced the cost of building large digital signage. To compare with the traditional flat billboards, the digital signage which has the advantages of audio-visuality, diversity, regionally, immediacy, differentiation, presence and interactivity is very suitable for use in the shopping malls. It can effectively display the characteristics of the counters and merchants and also the activity information to catch the customer's gaze focus. Customers can plan the best route for a limited time or download the latest information, discount coupons and navigation information via wireless transmission from their mobile device. The study is based on observations and comparisons of existing digital signage in shopping malls. Analyze the application of interactive digital signage in shopping malls to provide customers with a comfortable consumer environment and create a great service quality.

Digital signage network (DSN) is capable of delivering customized content to designated screens in a real-time or near real-time manner, which provides tremendous potential for building dynamic demand stimulation tools. However current DSN media buying process is mainly carried out through manually conducted negotiation between the DSN operator and the advertisers. This practice does not capitalize the unique technology advantage offered by the newly emerged advertising medium. We propose automated DSN media buying models which allow advertisers to customize their promotion schedules in a highly responsive manner. Specifically, we design a direct revelation mechanism and an iterative bidding model for DSN promotion scheduling. We show that the direct revelation mechanism computes optimal solutions. We evaluate the revenue performance of the iterative bidding model through a computational study. The implementation of the iterative bidding mechanism is also described.

Mobile phones have formed a social network within the phone subscriber population by allowing the phone subscribers to exchange information. Nowadays, smartphones have been improved with a variety of functionalities, such as a built-in cameras, motion sensors, and Wi-Fi wireless connectivity to enable the phone subscriber to take photographs of a desired object for distribution to other users through SMS or email. These functionalities make the mobile phones the perfect tool in terms of viral marketing within cellular phone subscribers. This thesis proposes a novel methodology that allows the phone subscriber to perform gestures for image acquisition from public signage displays. The public display is signage which displays a list of images in chronological order. The signage distributes the image list to nearby phones in the form of datagrams by means of multi-casts. Additionally, Wi-Fi connection between the phone and the signage must be established to enable multi-cast. When the phone has the completed image list downloaded, the phone subscriber can point the phone at the signage and perform a dragging gesture once he sees the desired image displayed by the signage. The current state of the project has concluded the development of the application to achieve the aforementioned task. However, the development of data transmission from one phone to another is still ongoing. Further development in the future would enable another gesture for data distribution to other phones in the vicinity. Web-based administration applications have also been developed to manage the image list in the signage. Through this web-based application, the administrator can generate new image list and then upload it to a FTP server. When the updated image list is stored in a remote FTP server, the signage periodically retrieves the image list from the FTP server. After the signage has received the updated image list, it then distributes the image list in the form of datagrams by means of multicasts. In summary, this thesis documents the impact of such technology in viral marketing research.

There are no identical definition and consistent translation for “Digital Signage” system in Taiwan, but in my research it is still translated into the Chinese language in terms of its generally-called title and functions. Actually, the digital signage market is gaining more credibility and visibility as an increasing number of commercial establishments are implementing digital signage for information, advertisements and entertainment with large flat displays. What is more, keeping abreast of the mess media, it is viewed as the fifth media channel. In other words, digital signage systems, not the technical breakthrough but the innovative media distribution with several technologies integrated effectively, are accounting progressively for the majority of the out of home media market in order to respond well to the challenging shifts in delivery and reception of messages. Therefore, they appear to the dynamic media solution to advertisers’ need to target the right message to a specific audience, who get fed up with jammed ads on the popular media. In 2004, the total value of displays in the worldwide retail signage market amounted to $664 million, iSuppli Corporation estimates. The market will grow to $2.35 billion in 2009, rising at a compound annual growth rate of 20 percent from 2004. Compared to the entire out of home media industry growing at a slower rate of 6 percent in U.S., it obviously shows that the digital signage market will continue to be expending with enormous potentiality. Accordingly, it is expected that the digital signage system is going to remain the most popular sign in out of home advertisement and to grow strongly to maturity during next few years. For all its benefits, digital signage is not without its disadvantages. Chief among these is cost, in addition to the lack of objective index to measurement and customized business models and so on. At this point, the major factor slowing adoption of digital signage is time-time for relative businesses to validate its use in their own environments. However, large numbers of installations are an issue not of “if” but of “when” by offering total solutions, whether in the world or in Taiwan. To date, high percentage penetrations of key markets continue to identify more concrete business drivers for rapid adoption of digital signage and to cumulate experiences to provide insights for the development of new products and service in this space. Despite these macro-economic and short-term obstacles, my research consequently paints a compelling picture that the long-term outlook for the digital signage industry is highly positive by means of leveraging relevant strategic theories, industrial news and interviews with senior managers in ADVANTECH. As a result, it is concluded that marketers need to bear in mind six keys to success that are generally simple in concept but often difficult in execution: 1. Repositioning from broadcasting media, turkey solutions must be highly targeted in terms of both commercial and public niches/applications to be the best choice of out of home media. 2. Extending from the traditional concept of the client-server relationship in mess media industry, system integrators and content providers will gain great controls and profits over other players in the value net of digital signage systems. 3. Most approaches will require an effective array of partners and components for success. 4. Critical market segments for digital signage is growing well and swiftly, but the opening window is such a short period that venders need to be fast movers to size the demand for enabling technologies and services. 5. Different segments have different needs to understand advertisers’ and brand managers’ perceptions, expectation, requirement, and plan for their digital signage system. 6. Facing the substitution from thin PC and various multimedia players, digital signage marketers must continue to support and even fund efforts to educate their adopters in order to convince them of having good prospects of gain.

After the proliferation of multi-media Internet technology, Innovation and diversity of content services are integrated with business model. They bring more development potential to this word. Digital advertisement has been widely used in physical business environment through various media. Today most commercial operators use digital signage in the liquid crystal system to push advertisement on the displays, then system providers also develop different digital signage systems that including stability, cost consideration, viewer’s visual communication feelings or other elements by based on industry category. Since the competitors and potential entrants had provided product service to customized system services, it has become the choice of product development strategy. In system development process, the design suggestions of digital signage were collection from literature review, then to be implemented in interface design. Including usability evaluation methods, evaluation of the dynamic interface design principles, and system usability scale were adopted at the stage of prototype evaluation. Using system usability scale could find out the performance from evaluators’ view. After that, there was a conclusion made by integrating the process of system interface design and the results of prototype evaluation: 1. Playlist is one of the necessary functions in digital signage system. Not only is it important to consider how to design the playlist and choose the suitable forms of media, but also it is important to seriously think about the requirement of operators. 2. According to the different forms of media, system interface must focus on each function’s logic and process design. To the whole interface, it is necessary to integrate and design consistency from each interface element. 3. System interface must focus on design of help and the feedback of error messages. So related research can improve the cognitive of correct operating activities by visual steps, guides of operating, and work flow charts. 4. Although system operating activities and user’s habits are considered in system development, then conforming to related system operating experiences. It is necessary to provide helps and documents.

Electronic digital signage is very worthy of study in recent years. According to the popularization of personal computers, the traditional billboards to digital is an inevitable trend, while there are many digital signage without the advantages of traditional billboards. Digital Video Broadcasting (DVB) protocol provides an alternative digital signage design, it does not use the Internet, while in DVB as the transmission mode, so that high-definition multimedia content can be steadily spread the display, so it can be removed to plug the control panel display side to significantly reduce system costs. Because DVB itself has broadcast features, implement synchronous multi-display digital signage easier and fit. This thesis is based on the DVB transmission technology, implementation, develop a functional and cost competitiveness of the digital signage system. In this thesis, using Ubuntu 12.04 with QT creator as a development platform for digital signage, computer software and provides many unique features, such as the integration of VLC, FFmpeg with gtk-recordmydesktop and other software features. Implementing digital signage from the perspective of integrating multimedia and ease of editing with the convenience and significantly reduce the amount of advertising spending, which is very worthwhile to continue in-depth research.

Internet of Things, Industry 4.0, access control systems, and modern intelligent office equipment have become important infrastructures for smart cities, and the PoE technology can transmit power and data to the device by Ethernet cable. In this thesis, we use the four pairs of Ethernet routes, and then through the self definition of PoE communication, re-design the PSE and the PD board, which can overcome the limitation of IEEE802.3af /at specification from 30 watt to 90 watt. The power supply on the Ethernet network is changed from two pairs to four pairs, which can greatly reduce the power consumption by 100 meters Ethernet cable. In addition, using the MOSFET to replace the Diode bridge rectifier can improve the overall efficiency, and solve the problem of thermal dissipation at the same time. Finally, re-design the fly-back circuit to synchronous rectification, and provide the power to end device. Currently, the power supply standards of various companies are not uniform. Although USB can be applied to most mobile devices or wearable systems, but it is still not enough for many industrial systems. Therefore, this research can be applied to the Digital Signage in Retail or department store, which can simplify the complexity and decrease cost of connection. Moreover, the heat problem also can be solved in 24-hour operation of system.

Dissertação de mestrado em Engenharia de Informática
O uso de painéis de digital signage ou displays (ou, em português, painéis digitais) está cada vez mais a ser implementado nos locais públicos e semipúblicos, uma vez que é uma forma actual de apresentar, de um modo dinâmico, informação, publicidade e conteúdos de entretenimento. Desta forma, as pessoas expostas a esta tecnologia passam a ter um acesso mais rápido e actualizado à informação sobre tudo o que as rodeia. Os ecrãs dos displays têm evoluído no sentido da melhoria da sua qualidade. Além disso, a descida dos preços torna esta tecnologia bastante mais acessível para ser aplicada em vários sectores, nomeadamente na indústria, no comércio, na educação, na saúde, etc., substituindo os meios tradicionais publicitários e informativos, baseados em papel. Uma rede de painéis digitais permite a actualização dos seus conteúdos de forma remota, com base num servidor central que controla toda a informação apresentada na rede, enquanto que nos meios tradicionais a actualização de conteúdos é muito mais cara, demorada e de difícil gestão. Como as pessoas olham pouco tempo para os painéis digitais, exige-se um esforço muito grande no estudo do local onde estes são instalados e na modelação dos conteúdos a serem apresentados, de forma a que o ambiente se torne o mais atractivo possível e, deste modo, se promova a atenção de quem passa pelos painéis. Também existem displays que usam tecnologias mais sofisticadas, permitindo a adaptação automática dos conteúdos apresentados em função do contexto envolvente, fazendo com que a informação seja mais direccionada ao público, sem a necessidade de controlo humano. Dado o crescente sucesso, à escala planetária, da digital signage, têm surgindo cada vez mais soluções de software aplicadas nesta vertente. Por conseguinte, o tema principal desta dissertação incidirá sobre o desenvolvimento de uma aplicação web para painéis de digital signage, sugerida pela empresa Ubisign, com o objectivo de permitir configurar visualizações com informação sobre eventos provenientes do Google Calendar. Uma vez que a promoção de eventos geralmente exige custos elevados de design e produção, é necessário minimizá-los no contexto das redes de digital signage. Para tal, existem determinadas ferramentas on-line de gestão de eventos, como o Google Calendar, com a função de permitir que o utilizador especifique eventos que vão ocorrer e efectue o seu escalonamento com base em calendários. Do ponto de vista de um developer, estas ferramentas evitam a necessidade de implementar outros softwares de gestão de eventos, permitindo também desenvolver outras aplicações que comuniquem com estas ferramentas, através de APIs apropriadas e bem documentadas. Para tirar partido disto, a aplicação a desenvolver terá de recorrer à API Google Calendar para disponibilizar, de forma personalizada, informação sobre eventos que estejam planeados para um dado sítio com uma rede de digital signage instalada e, para esse efeito, terá de ser integrada no serviço Ubisign.com.
The usage of digital signage displays in public and semi-public places is increasing, because they are a modern way of dynamically displaying information, advertisements and entertainment content. In this way, those exposed to digital signage have a quick and up to date access to information around them. Display screens have been improving in quality. Also prices have been falling, making this technology more affordable in order to be applied in various areas (particularly in industry, commerce, education, health, etc.), replacing the paper-based traditional means of advertising and information [Müller, 2009]. A digital signage network allows the remote update of its contents, based on a central server that manages all the information presented on the network, while in traditional means the contents’ updating process is much more costly, time consuming and difficult to manage. Because people glance briefly into the displays, their content and locus must be carefully studied, so that the environment becomes more attractive. Thus it is a way to promote the attention of the passersby [Huang et al., 2008]. Some displays use more sophisticated technologies, allowing a contextbased automatic adaptation of their content. So the information is targeted to the public, without the need for human control [Müller, 2007, Payne et al., 2006]. Ever more software solutions applied to digital signage have emerged due to its increasing success in a worldwide scale. Therefore the development of a digital signage web application that allows the set up of views with event information coming from Google Calendar (proposed by Ubisign company) will be the main theme of this dissertation. Since event promotion generally requires high costs of design and produc tion, they must be minimized in digital signage networks. To this end, some online tools for managing events, such as Google Calendar, allow calendarbased event scheduling and its specification. From a developer’s perspective, these tools avoid the need to implement other event management software, allowing one to develop other applications that communicate with these tools through appropriate and well documented APIs. To take advantage of this, the application that will be developed will need to use the Google Calendar API to provide information in a personalized way about events that are planned for a given place with an installed digital signage network. For this purpose, the application must be integrated in the Ubisign.com service. Area of Application: Information Interfaces and Presentation. Keywords: Digital Signage Displays; Google Calendar; Event Information.
