Texto completoDue to the growth of video traffic over the Internet in recent years, HTTP AdaptiveStreaming (HAS) solution becomes the most popular streaming technology because ithas been succesfully adopted by the different actors in Internet video ecosystem. Itallows the service providers to use traditional stateless web servers and mobile edgecaches for streaming videos. Further, it allows users to access media content frombehind Firewalls and NATs.In this thesis we focus on the design of a novel video streaming delivery solutioncalled Backward-Shifted Coding (BSC), a complementary solution to Dynamic AdaptiveStreaming over HTTP (DASH), the standard version of HAS. We first describe theBackward-Shifted Coding scheme architecture based on the multi-layer Scalable VideoCoding (SVC). We also discuss the implementation of BSC protocol in DASH environment.Then, we perform the analytical evaluation of the Backward-Sihifted Codingusing results from queueing theory. The analytical results show that BSC considerablydecreases the video playback interruption which is the worst event that users can experienceduring the video session. Therefore, we design bitrate adaptation algorithms inorder to enhance the Quality of Experience (QoE) of the users in DASH/BSC system.The results of the proposed adaptation algorithms show that the flexibility of BSC allowsus to improve both the video quality and the variations of the quality during thestreaming session.Finally, we propose new caching policies to be used with video contents encodedusing SVC. Indeed, in DASH/BSC system, cache servers are deployed to make contentsclosed to the users in order to reduce network latency and improve user-perceived experience.We use Linear Programming to obtain optimal static cache composition tocompare with the results of our proposed algorithms. We show that these algorithmsincrease the system overall hit ratio and offload the backhaul links by decreasing thefetched content from the origin web servers

Texto completoThis Master dissertation has the aim of study, and further develop, a tool that allows to gather Quality of Experience metrics, in the Web browsing context, in order to perceive, as close to reality as possible, the experience that real users would have during the navigation in webpages. The gathering of Quality of Experience and Service metrics are essential for telecom operators, in order to diagnose the quality of services and, consequently, perceive the level of satisfaction of its clients. In this context, the solution was an application that acts independently and performs tests, that allow to infer the experience that a real user would face during the access to a webpage, through a real browser. The solution is able to: extract time metrics, information related with the Web navigation, the status of the webpage and its resources. Furthermore, it allows to con gure simple or more complex interaction test scenarios with the webpage, take screen captures during the test execution and even download all the les belonging to the webpage that were loaded. The solution was tested in order to evaluate its performance and returned values (metrics) reliability, comparing with a real navigation values.
Esta dissertação de Mestrado tem por objectivo o estudo e o desenvolvimento de uma ferramenta de aferição de métricas de Qualidade de Experiência, no contexto da navegação Web, de modo a percepcionar, da forma mais real possível, a experiência dos utilizadores comuns na navegação em paginas Web arbitrarias. A obtenção de métricas que permitam determinar a Qualidade de Experiência e de Serviço são uma ferramenta essencial para as operadores de telecomunicações, de forma a diagnosticar o nível de qualidade dos serviços prestados e, consequentemente, perceber o grau de satisfação dos clientes. Neste contexto, a solução desenvolvida foi uma ferramenta que actua de forma independente e efectua testes que permitem aferir a experiência a que um utilizador normal estaria sujeito face a navegação numa pagina Web, num browser real. Assim, a aplicação desenvolvida e capaz de: extrair intervalos temporais para inferir a qualidade da experiência, informações acerca da navegação e do estado da pagina Web, bem como dos seus componentes. Para alem disso, permite configurar cenários de interacção simples ou complexos com a pagina, tirar capturas de ecra em vários momentos durante o correr do programa e ainda, permite descarregar todos os ficheiros que compõem a pagina Web, que foram carregados. Esta solução foi sujeita a testes de averiguação do desempenho e da contabilidade dos valores devolvidos (métricas) pela mesma, quando comparados com uma navegação real.

Texto completoAnvändningen av mobila tjänster som utnyttjar video streaming växer i en snabb takt. I och med att antalet webbtjänster som utnyttjar video streaming ökar, finns det även ett växande intresse för att förstå Quality of Experience (QoE) för användningen av dessa tjänster, samt olika faktorer som inverkar på tjänstens QoE. QoE har en direkt inverkan på kundbevarande, vilket innebär att dålig QoE leder till förlorade intäkter för videotjänster. En videotjänsts kundupplevelse kan objektivt mätas med variabler som t.ex. antalet buffringspauser under tiden som videon spelas, samt tiden det tar för en video att börja spela. Att samla dessa data för analys på en större skala utgör en stor utmaning. I denna avhandling diskuterar vi arbetet som gjorts inom utvecklingen av ett system som samlar in och analyserar dessa variabler. Majoriteten av arbetet omfattar utvecklandet av en mobilapplikation som automatiskt spelar upp en lista av videon vid inställbara intervall, och under uppspelningen bandar in intressanta händelser så som statistik över systemet och nätverksanvändning, samt videospelarens händelser. Applikationen har blivit publicerad och kan användas från olika platser för att samla in en stor uppsättning data för detaljerad analys och modellering av QoE inom mobil Internet-video streaming.

Texto completoFourth-generation mobile networks, based on the Long Term Evolution (LTE) standard, are all- IP networks. Thus, mobile telephony providers are facing new types of quality degradations related to the voice packet transport over IP network such as delay, jitter and packet loss. These factors can heavily degrade voice communications quality. The real-time constraint of such services makes them highly sensitive to delay and loss. Network providers have implemented several network optimizations for voice transport to enhance perceived quality. However, the proprietary quality management algorithms implemented in terminals are left unspecified in the standards. In this context, we are interested in media adaptation mechanisms integrated in terminals to enhance the overall Quality of Experience (QoE). In particular, we experimentally evaluate Voice over LTE (VoLTE) QoE metrics such as delay and Mean Opinion Score (MOS) sing a standardized test method. We propose some enhancements to the actual test method and discuss how this method can be extended to evaluate de-jitter buffer performance. We also experimentally evaluate WebRTC voice quality in different radio conditions using a realLTE test network. We evaluate the impact of jitter buffer and bit rate variations on the measured quality. To enhance voice codec robustness against packet loss, we propose a simple application layer redundancy. We implemented it for the Enhanced Voice Service (EVS) codec and evaluate it. Finally, we propose a signaling protocol that allows sending redundancy requests during a call to dynamically activate or deactivate the redundancy mechanism

Texto completoToday user experience is becoming a reliable indicator for service providers and telecommunication operators to convey overall end to end system functioning. Moreover, to compete for a prominent market share, different network operators and service providers should retain and increase the customers’ subscription. To fulfil these requirements they require an efficient Quality of Experience (QoE) monitoring and estimation. However, QoE is a subjective metric and its evaluation is expensive and time consuming since it requires human participation. Therefore, there is a need for an objective tool that can measure the QoE objectively with reasonable accuracy in real-Time. As a first contribution, we analyzed the impact of network conditions on Video on Demand (VoD) services. We also proposed an objective QoE estimation tool that uses fuzzy expert system to estimate QoE from network layer QoS parameters. As a second contribution, we analyzed the impact of MAC layer QoS parameters on VoD services over IEEE 802.11n wireless networks. We also proposed an objective QoE estimation tool that uses random neural network to estimate QoE from the MAC layer perspective. As our third contribution, we analyzed the effect of different adaption scenarios on QoE of adaptive bit rate streaming. We also developed a web based subjective test platform that can be easily integrated in a crowdsourcing platform for performing subjective tests. As our fourth contribution, we analyzed the impact of different web QoS parameters on web service QoE. We also proposed a novel machine learning algorithm i.e. fuzzy rough hybrid expert system for estimating web service QoE objectively

Texto completoDenna rapport jämför en “Native Android”-applikation med två olika klasser av plattformsoberoende applikationer, en “Interpreted”-applikation utvecklad i React Native och en “Progressive Web”-Applikation (PWA). Det största bidraget från denna rapport är en jämförelsetabell, där applikationsfunktioner placeras på y-axeln och de utvärderade ramverken på x-axeln. Denna tabell, i konjunktion med en kostnadsanalys, förser läsaren med en tydlig guide vid val av ramverk. De utvärderade applikationerna skapades för att utvärdera ramverkens tillgänglighet till de uppräknade funktionerna. En användarstudie utfördes för att utreda huruvida det existerade någon märkbar skillnad mellan de utvärderade applikationerna. De kvalitativa data som erhölls från en “think-aloud” i användarstudien indikerar en liten preferens för PWA:n, trots att den har tillgång till färre funktioner. Den kvantitativa analysen från ett “User Experience Questionnaire” (UEQ) misslyckades med att visa någon systematisk skillnad i UX mellan de utvärderade applikationerna. Slutsatsen är därför att plattformsoberoende applikationer både kan emulera, och till och med överträffa, en naturlig upplevelse i vissa avseenden, med en ytterligare fördel av att både utvecklings- och underhållskostnader väsentligt minskar. Slutligen rekommenderar vi användandet av ett plattformsoberoende applikationsramverk förutsatt att det har tillgång till alla funktioner som krävs för den avsedda applikationen.

Texto completoThe thesis is centered on the relationship of Quality of Service (QoS) and Quality of Experience (QoE) for mobile Internet services. While QoS covers the technical view on the telecommunications network characterized by performance-related parameter values (e.g. throughput and latency), QoE refers to the assessment of the user experience (e.g. satisfaction and acceptability) in the use of the services. In the thesis QoS and QoE are revealed as highly complex and related concepts in theoretical contemplation. Integrating both concepts requires a multidisciplinary or interdisciplinary approach between engineering and human sciences to consider both - technological aspects of the network as well the human user. The designed multilayered model appropriately integrates the technical network view as well as the user's perspective by considering all relevant factors of influence and all internal relationships between QoS and QoE. The conducted extensive psychophysical laboratory experiment with real users, devices and services quantifies the relationship between specific QoS values and specific QoE values. A testbed developed for network emulation allows combining typical mobile network situations with typical usage situations in a controlled and focused manner. The three elaborated principles to test for relevance, suitability and efficiency take into account the special features of the test setup and test design. Test results gained from more than 200 volunteers confirm the predicted QoS-QoE-characteristics of the six tested mobile services to be either elastic or non-elastic. It is possible to conclude from the desired degree of user satisfaction on the necessary values of the QoS network parameters, which results in a QoS-QoE-corridor between lower and upper threshold values. Findings prove that QoS-independent factors, e.g. the type of presentation of the stimuli in the app on the user’s device, can be as relevant for QoE as the evaluated QoS network parameters themselves

Texto completoInternet har dominerat modern kommunikation och informationsutbyte och den växer enormt varje dag. Inledningsvis är det för att stänga? ER olika tillämpningar som World Wide Web (WWW), elektronisk post (e-post) och filöverföring (ftp). WWW har blivit mycket populärt och idag utgör webbtrafik 70-80% i den globala Internet-trafiken.

Texto completoMobiloperatörer möter ett scenario som kännetecknas av en ökande trend inom dataförbrukning, tecken på en avmattning i abonnenttillväxten, en en minskning av de traditionella intäkter på grund av framgången med OTT leverantörer. Dessutom, mobila användare har gott om alternativ för att ändra tjänsteleverantören. I det här fallet måste mobiloperatörer förbli konkurrenskraftiga baseras både på pris och deras abonnenter tillfredsställelse. Kvalitet Erfarenhets (QoE) införlivande i mobilnät kan vara ett av alternativen för att möta vissa mobilbranschen utmaningar som omfattar tekniska, kommersiella och marknadsnivå. QoE möjliggör en bredare och mer övergripande förståelse av användarnas erfarenheter med utförandet av applikationer, tjänster och nätverk, samtidigt som kompletterar traditionella techno-centric begrepp som Quality of Service(QoS). Händelse om användningen av QoE data har föreslagits som ettsätt att lösa problem som optimering av nätverksresurser och kundomsättning upplevs av mobiloperatörer, finns det fortfarande en lucka på hur man utnyttjar QoE och dess potentiella fördelar i ramen för mobilnät. Således är den övergripande inriktningen av denna avhandling på att analysera hur mobiloperatörer kan integrera QoE feedback för att förbättra sin serviceerbjudande.Men på grund av arten av de utmaningar som den mobila industrin står inför, denna analys kan inte begränsas till en teknisk nivå diskussion. även hitta en teknisk lösning skulle kunna vara det första steget för att övervinna utmaningarna på marknaden, är det viktigt att ett tekniskt beslut kommer tillsammans med en välgrundad analys av de regulatoriska förutsättningarna för att genomförandet och affärs konsekvenserna av den föreslagna lösningen.Så kan en skådespelare intresserad av genomförandet av det föreslagna i dennaavhandling mekanism har fler verktyg för ett välgrundat beslut fattandet. På teknisk nivå, fokuserar denna uppsats på identifiering av teknisk mekanismför att införliva QoE i mobilnätet. Sedan vår analys kretsar kring identifieringen av regelverket om nätneutralitet och dess potentiella inverkan på genomförandet av den föreslagna mekanismen för införliva QoE i mobilnät. Slutligen, och letar efter en helhetssyn på QoE frågan, erbjuder vi en analys av konsekvenserna av att införliva QoE för hela mobilnät ekosystemet och intressenterna längs hela värdenätverket.

Texto completoFör många människor är det svårt att ta stora beslut, att bygga hus är ett av dessa. Det är kanske den största investeringen och projekt som man tar sig an. I ett husbygge är det många saker som ska stämma överrens, man ska hitta en tomt, välja en husmodell och till sist alla de där andra valen som till exempel köks- och badrumsdetaljer. Det är i detta beslutskede som det kan vara skönt att kunna testa olika husmodeller och material innan det slutliga beslutet tas. Det är denna process som är i fokus i detta examensarbete, eller rättare sagt ett verktyg för att underlätta besluten. Det handlar nämligenom en AR-applikation för hus. AR står för augmented reality(förstärkt verklighet) och med hjälp av denna kan användaren se sitt hus i verklig storlek på tomten innan någonting är bestämt eller ens påbörjat. Neava AB har utvecklat en applikation där det i dagsläget går att visa en AR-modell av ett hus i verklig storlek. Deras huvudsakliga kunder är husföretag som bygger modulära hus. Då teamet på Neava AB arbetat med att utveckla kundanpassade konfiguratorer för virtuell verklighet har några utmaningar börjat visa sig.Det tar lång tid att komma överens om vilken färgnyans som är korrekt och kommunikationen i detta skede av produktionen tar iblandväldigt lång tid varvid Neava måste invänta kundens bedöming påderas modeller. Detta problem är också kopplat till kundernas grafiska profil då kunderna alla har en specifik framtoning och vill att både gränssnitt och bilder ska återspegla denna så starkt som möjligt. Målsättningen med arbetet är att utforska hur ett verktyg för husföretagen att skapa sina egna gränssnitt skulle kunna se ut. Gränssnittet designas med fokus på användbarhet och användarupplevelse och utvärderas kontinuerligt jäntemot dessa kriterier. Projektet tillämpar en användarcentrerad designprocess där det centrala är att involvera användarna i designprocessen på olika sätt. Detta arbete tillämpar intervjuer, enkäter, utvärderingar och användartester genomgående för att kontrollera hur väl resultaten stämmer överrens med de identifierade behoven. Designen tas fram med utgånspunkt i de identifierade utmaningar och problem som funnits med hjälp av dessa metoder.Resultatet är ett koncept som illusterar hur detta verktyg skulle kunna se ut och fungera. Både hur en konfigurator för AR men också för hur en administrativ tjänst för en huskonfigurator skulle kunna se ut.Genom att designa gränssnittet för huskonfiguratorn i AR och medföljande administrativa tjänst så kunde ett förslag för detta verktyg presenteras. Om Neava skulle utveckla detta verktyg så skulle det både minska tiden som de lägger på kommunikation, men också ha tagit fram en innovativ och nytänkande produkt som kan bidra till att minska miljöpåverkan av nybyggnation genom säkrare beslut och minskad ombyggnation.

User eXperience (UX) refers to a holistic perspective and an enrichment of traditional quality models with non-utilitarian concepts, such as fun, joy, pleasure, hedonic value or ludic value. In order to evaluate UX in software applications, several technologies (tools, methods, techniques) have been proposed that range from using questionnaires to employing biometrics to gather quantitative and qualitative data on users’ experience. However, there is a need for research in the development of specific UX evaluation technologies that are easy and comfortable to use from the point of view of users, while supporting software engineers in the correction of the aspects that cause poor experiences. Additionally, new UX approaches should be proposed for evaluating mobile applications, as there is still a shortage of methods for this type of applications, which is rising in demand. This doctoral dissertation proposes an alternative approach for evaluating mobile applications called Redesigning for EXperience (REX), which intends to be less intrusive for users when extracting UX data, while generating reports containing design suggestions for improving the UX. We assessed the acceptance of the initial versions of the REX approach from the point of view of users and software engineers in two studies. When compared to 3E, a qualitative UX evaluation method, the results showed that REX was perceived as more fun, useful and more interactive. Additionally, software engineers considered REX useful and easy to understand, while suggesting improving its report to facilitate its understanding and increase its use. After working on the improvements opportunities from the empirical studies, we developed a tool support for the REX approach called the REX report generator. Also, we carried out an observational study to verify to which extent the REX approach could be applied in a real software development project. Thus, REX was employed by users to evaluate a mobile educational application and a discussion meeting was held with the software development team to discuss the improvement suggestions provided by REX to support the redesign process. The findings from the observational study indicated the satisfaction of users to report their experience with the REX approach, while the members of the development team agreed with the usefulness of the REX report and its improvement suggestions. By providing design suggestions, we aim to support software engineers in improving the UX of the developed mobile applications, thus increasing their quality and acceptance in the market.

Texto completoIn recent years, smartphone and tablet global performances have been increased significantly (CPU, screen resolution, webcams, etc.). This can be particularly observed with video quality of mobile media services, such as video streaming applications, or interactive applications (e.g., video games). However, these evolutions barely go with the integration of high quality sound restitution systems. Beside these evolutions though, new technologies related to spatialized sound on headphones have been developed, namely the binaural restitution model, using HRTF (Head Related Transfer Functions) filters.In this thesis, we assess the potential contribution of the binaural technology to enhance the quality of experience of an audiovisual mobile application. A part of our work has been dedicated to define what is an “audiovisual mobile application”, what kind of application could be fruitfully experienced with a binaural sound, and among those applications which one could lead to a comparative experiment with and without binaural.In a first place, the coupling of a binaural sound with a mobile-rendered visual tackles a question related to perception: how to spatially arrange a virtual scene whose sound can be spread all around the user, while its visual is limited to a very small space? We propose an experiment in these conditions to study how far a sound and a visual can be moved apart without breaking their perceptual fusion. The results reveal a strong tolerance of subjects to spatial discrepancies between the two modalities. Notably, the absence or presence of individualization for the HRTF filters, and a large separation in elevation between sound and visual don’t seem to affect the perception. Besides, subjects consider the virtual scene as if they were projected inside, at the camera’s position, no matter what distance to the phone they sit. All these results suggest that an association between a binaural sound and a visual on a smartphone could be used by the general public.In the second part, we address the main question of the thesis, i.e., the contribution of binaural, and we conduct an experiment in a realistic context of use. Thirty subjects play an Infinite Runner video game in their daily lives. The game was developed for the occasion in two versions, a monophonic one and a binaural one. The experiment lasts five weeks, at a rate of two sessions per day, which relates to a protocol known as the “Experience Sampling Method”. We collect at each session notes of immersion, memorization and performance, and compare the notes between the monophonic sessions and the binaural ones. Results indicate a significantly better immersion in the binaural sessions. No effect of sound rendering was found for memorization and performance. Beyond the contribution of the binaural, we discuss about the protocol, the validity of the collected data, and oppose theoretical considerations to practical feasibility
