Full textAtualmente, metade da população mundial (55%) habita em centros urbanos, em 2050 estima-se que aumente para dois terços (68%). Estes espaços ocupam apenas 3% da superfície do planeta, mas consomem 75% dos recursos naturais. Em 2016 entrou em vigor a resolução da Organização das Nações Unidas (onu) intitulada “Transforming our world: the 2030 Agenda for Sustainable Development”, como base para um plano de ação para as pessoas e o planeta prosperarem. A mais recente Conferência das Nações Unidas sobre Mudanças Climáticas (cop 21) explorou soluções para enfrentar as consequências do aquecimento global e traçou objetivos globais de redução de gases de efeito estufa. O turismo, uma atividade em crescimento, é parte deste problema global. Gera riqueza e poluição tendo impacto em fenómenos que ameaçam o futuro do planeta: as alterações climáticas, o consumo excessivo, o desperdício de plástico, a perda de biodiversidade, a sobrecarga das cidades, o uso de combustíveis fósseis, o consumo energético. Daí a importância cada vez maior de um turismo sustentável. O presente projeto de investigação pretende, através do design, contribuir para a criação e promoção de um novo negócio, nesta área com forte potencial de crescimento – o turismo. Materializa-se através da participação numa ideia de negócio, apoiando o seu desenvolvimento desde o início, assumindo a dimensão estratégica que o design pode ter, não só na construção da comunicação mas também no desenvolvimento e concretização da própria ideia e do seu financiamento. Esta investigação surgiu da identificação de uma oportunidade de negócio, numa área que tem apresentado um interesse crescente por parte do público. Estudou-se o mercado e o contexto onde este negócio se pode desenvolver e ainda o interesse das visitas aos espaços verdes pois eles corporizam a estratégia ambiental das cidades modernas e contam grande parte da sua história. Sem árvores as cidades seriam muito diferentes. Partindo de uma metodologia de base qualitativa, efetuou-se uma investigação de carácter teórico, através da revisão da literatura dos campos investigativos: Turismo e Design de Comunicação. Assim, desenvolveu-se um enquadramento teórico capaz de impulsionar e direcionar a componente projetual. Numa segunda fase, procedeu-se à análise de casos de estudo, compreendendo o modo como negócios internacionais, que exploram o mesmo nicho, se apresentam e divulgam a sua oferta. De seguida, foram analisados fatores relacionados com a implementação do projeto: análise swot, caracterização do público-alvo, identificação de potenciais concorrentes. Esta investigação, resulta na materialização de um projeto singular que pretende atuar num nicho de mercado, explorando e valorizando jardins e espaços verdes urbanos. Propondo dar a conhecer a história e a vida das cidades, através dos seus jardins, quer tenham centenas de anos ou menos de uma década. Despertando o interesse para o ‘verde’ – Green Eye.
ABSTRACT: Today, half of the world’s population (55%) live in urban centers, it is estimated to increase to two-thirds (68%) by 2050. Although they consume 75% of natural resources, these areas occupy only 3% of the earth’s surface. In 2016, United Nations Organization’s resolution called “Transforming our world: the 2030 Agenda for Sustainable Development” came into force as a foundation for a plan of action so that the planet and man could prosper. United Nations’ most recent conference about climate changes (cop 21) explored solutions to deal with global warming consequences and set worldwide goals in order to reduce greenhouse gases. Tourism is part of this problem . A growing activity which generates wealth and pollution. Tourism has positive aspects, however, it also has an impact on phenomena that threaten the future of the planet: climate change, excessive consumption, plastic waste, loss of biodiversity, the overburden of cities, use of fossil fuels, energy consumption, discharges. That is why having sustainable tourism is increasingly important. Resorting to design, this research project intends to contribute to the creation and promotion of a new business, in an area with strong growth potential – tourism . It is materialized through participation in a business idea, supporting its development from the beginning. Assuming the strategic dimension that design can have, not only in the construction of communication but also in the development and implementation of the idea itself and its financing. This research emerged from the identification of a business opportunity, in an area that has shown a growing interest by the public. The market and the context, where this business can be developed, were studied. The interest of the visits to the green spaces was also studied because they embody the environmental strategy of modern cities and they tell much of their history (and of their own stories). From a qualitative methodology, a theoretical investigation was carried out, through the literature review of the research fields: Tourism and Communication Design. Thus, a theoretical framework capable of boosting and directing the project component has been developed. In a second phase, case studies were analyzed, including the way in which international businesses, which explore the same niche, present themselves and disseminate their offer. Next, we analyzed factors related to project implementation: swot analysis, characterization of target audience and identification of potential competitors. As a result of this research, we have accomplish a singular project that intends to operate in a market niche, exploring and valuing gardens and green spaces in the city. Proposing to introduce the history and life of cities, through their gardens, whether they have hundreds of years or less than a decade. Awakening interest for the ‘green’ — Green Eye.

Full textThis thesis has been done in collaboration with the Swedish eye tracking company Tobii AB, at the department Tobii Tech. The purpose has been to investigate what humanized technology means and how Tobii’s product EyeX can enhance a more natural and humanized interaction with the computer. This work has been conducted throughout an explorative approach; using secondary sources from relevant literature and qualitative studies; divided in a theoretical and practical part. Firstly, a theoretical part was conducted to gain general knowledge about the eye tracking and its different areas of implementation. Currently, eye tracking can be found in various fields of research and communication tools for people with neurological disabilities. Contrary to those application areas of eye tracking, EyeX is aimed for the consumer and gaming market and therefore the work is limited to able-bodied users. This was continued by research concerning: human interactions and humanization in human-computer interaction. The theoretical part of this project created a foundation for how relationships are created and how emotional aspects of human characteristics could possibly be related to computer interaction. It also described how a meaningful and lasting relationship could be created with computers and their various features by the means of habits. Furthermore, the work continued with the practical part: three workshops, performed to further understand the relevance of the results from the related work and qualitative data collection through interviews and observations with EyeX users. By the end of the user study it could be assumed that emotional aspects of human characteristics was essential for the development of interfaces and therefore should be implemented in human-computer interactions. Finally, a supplementary workshop was conducted to clarify how emotional and abstract factors could easier be related to practical eye tracking and computer features. Also, two evaluation methods were created for evaluating humanization and emotional aspects in features/products.

Full textTobii AB arbetar med en teknik kallad eye tracking, som syftar till att läsa av ögonrörelser. TobiiDynavox, en del i Tobii AB, utvecklar för närvarande en ny produkt, kallad Ergo, som nyttjar den tekniken. Syftet med produkten är att minska fysisk smärta i samband med datoranvändninggenom att låta användaren styra datorn med ögonen istället för med händerna. Produkten ärriktad mot en ny marknad för Tobii Dynavox, en marknad med andra kunder ochanvändargrupper än deras nuvarande. Med anledning av detta behöver Tobii Dynavox en störreförståelse för Ergos blivande kunder. De frågor som undersökningen ämnar att besvara ärföljande: Hur ser marknaden för ergonomiska hjälpmedel ut? Hur ser kundresan med Ergo ut? Vilka är de potentiella kunderna och vilka behov har de? Hur bör Ergo vara designad och bli presenterad för att användaren lättare ska ta till sig produkten?För att undersöka detta genomfördes en kontextuell undersökning av Ergo. Undersökningbestod av en literaturstudie, användarstudie, en studie av Tobiis företagsidentitet och marknadenav ergonomiska hjälpmedel. Undersökningen resulterade i insikter som sammanfattades i en listamed riktlinjer. Dessa riktlinjer är väsentliga i utvecklingen av Ergo för att få en produkt som äranvändarvänlig, lönsam för Tobii, mer trovärdig på marknaden och redo för marknadslansering.Insikterna resulterade även i en sammanställning av problemområden med Ergo, från vilket ett valdes ut för fortsatt utveckling. Det problem som valdes var användarnas varierande förväntningar av produkten och deras svårigheter att ta till sig produkten. Utvecklingen av Ergo innefattade ett förslag för att lösa det valda problemet. Lösningen är en nyproduktdesign som genom en linjär inlärningsprocess underlättar för användaren att ta till sigprodukten och använda den i sitt dagliga arbete. Designen ska därtill vara mer ledande, intuitiv, lättsam och förmedla ett snällt men också spännande intryck. Slutsatsen från utvärderingen visade att den nya designen är fördelaktig för Ergo, då den underlättar för användaren att ta till sig eyetracking i dagligt arbete.

Full textThe goal of study 1 was to use a remote eye tracker to understand how eye movements change with 7 geometrically varied remote controls to determine design element saliency. 20 participants were used to measure the following eye metrics: number of fixations prior to first fixation of any AOI, time to first fixation of an AOI, number of fixations on an AOI, dwell time of the first fixation on an AOI, total dwell time of an AOI, and the percentage of time spent on an AOI. The results of the study showed that all participants spent between 75–85% of their time fixated on the button layout which was not defined as an AOI. No statistical differences were found in the values measured for all eye tracking metrics across similarly defined AOIs. In study 2, the objective was to determine attitudes towards appearance and usability of the 7 remote control designs using the participants from study 1. Participants were asked to rate their attitudes and preferences, using a Likert-based questionnaire, about the qualities of appearance and usability for the attributes of proportion, shape, and configuration. They were asked open-ended questions about their likes and dislikes regarding the qualities of appearance and usability. Lastly, participants were given a pairwise comparison survey where they chose their preferred remote design, based on appearance, for 10 paired sets of contrasting remote designs. The hourglass subjacent and hourglass round designs were rated highest for appearance and usability from the Likert questionnaire. The hourglass round design was ranked highest for the pairwise comparison survey. For study 3, the goal was to determine attitudes towards appearance and usability of the 7 remote designs with online participants. 300 participants were asked to rate their attitudes and preferences using the same Likert-based questionnaire from study 2. They were asked the same open-ended questions and administered the same pairwise comparison survey as in study 2. The results of the Likert questionnaire showed that the hourglass subjacent and hourglass round designs were rated highest for appearance and usability. From the pairwise comparison survey, the hourglass round design was ranked the highest.

Full textThis paper examines the impact of a multicultural approach on the usability of web and software interface designs. Through the use of an eye-tracking system, the study compares the ability of American users to navigate traditional American and Japanese websites. The ASL R6 eye-tracking system recorded user search latency and the visual scan path in locating specific items on the American and Japanese pages. Experimental results found statistically significant latency values when searching for left- or right-oriented navigation menus. Among the participants, visual observations of scan paths indicated a strong preference for initial movements toward the left. These results demonstrate the importance of manipulating web layouts and navigation menus for American and Japanese users. This paper further discusses the potential strengths resulting from modifications of interface designs to correspond with such cultural search tendencies, and suggestions for further research

Full textO Mesurer avec précision les mouvements oculaires constitue un élément essentiel dans ledomaine de la neuroscience. Par exemple, capter les mouvemets de l'oeil contribue à la compréhension de la relation entre les activités neuronales et le comportement oculaire. De meme, les irrégularités observées dans les mouvements des yeux aident à diagnostiquer et à surveiller le progrès de plusieurs troubles mentaux comme la démence. En plus, le tracement de la trajectoire oculaire peut être utilisé pour construire des interfaces homme-machine pour les personnes sévèrement handicapées.Bien que plusieurs techniques de tracement oculaire existent déjà, la bobine de recherche magnétique est fortement utilisée par les chercheurs. Elle offre une haute exactitude et une très bonne précision de mesure. La technique traditionnelle exige l'utilisation de grandes bobines de champs, nécessitant ainsi que la tête du sujet soit fixée en tout temps. En revanche, on propose l'utilisation d'un système de bobines miniaturisées construit avec la technologie MEMS. Les bobines ont été conçues à l'aide des logiciels CoventorWare et MagNet. Les micro-bobines ont été fabriquées dans le laboratoire de micro-fabrication Nanotools de l'Université McGill. On présente les résultats obtenus en utilisant des micro-bobines construites avec la solution solide de l'oxyde de l'étain et l'oxyde de l'indium (ITO). Le système de micro-bobine est capable d'identifier les déplacements dans les trois dimensions X, Y, et Z. La résolution du système dépend de la configuration utilisée. On a trouvé que la résolution peut être entre 20 et 40 μm. Le système proposé est très promettant mais plusieurs tests exhaustifs deraient encore être appliquées dans des environnements qui simulent de vrais mouvements oculaires.

Full textVågfrontssensorer för mätningar på ögon är ofta mycket stora, dyra och svåra att transportera. En kompakt vågfrontssensor skulle vara kostnadseffektiv och flexibel eftersom den skulle kunna användas i flera olika system. Målet med detta examensarbete var att producera en mer kompakt och transportabel vågfrontssensor. En kortare teleskopvariant föreslogs och analyserades både teoretiskt och med datorsimuleringar. En experimentell uppsättning gjordes också för att jämföra den kortare teleskopdesignen med ett sedvanligt vågfrontssensorteleskop. En kompakt vågfrontssensor byggdes med standardkomponenter samt med några modifierade standardkomponenter. Tester med den kompakta vågfrontssensorn gjordes både på ögonmodeller och mänskliga ögon. Den kompakta vågfrontssensorn gav korrekta mätvärden på brytningsfelen på ögonmodellerna. Det gick bra att genomföra mätningar på mänskliga ögon, både i centrala och perifera synfältet, och högre ordningens aberrationer bekräftades. För att placera mänskliga ögon på korrekt avstånd från vågfrontssensorn krävdes en extra pupillkamera, som inte var inkluderad i den kompakta vågfrontssensorn. Framtida förbättringar för den kompakta vågfrontssensorn diskuteras.

Full textHuman-Machine Interaction (HMI) progressively becomes a part of coming future. Being an example of HMI, embedded eye tracking systems allow user to interact with objects placed in a known environment by using natural eye movements. The EyeDee™ portable eye tracking solution (developed by SuriCog) is an example of an HMI-based product, which includes Weetsy™ portable wire/wireless system (including Weetsy™ frame and Weetsy™ board), π-Box™ remote smart sensor and PC-based processing unit running SuriDev eye/head tracking and gaze estimation software, delivering its result in real time to a client’s application through SuriSDK (Software Development Kit). Due to wearable form factor developed eye-tracking system must conform to certain constraints, where the most important are low power consumption, low heat generation low electromagnetic radiation, low MIPS (Million Instructions per Second), as well as support wireless eye data transmission and be space efficient in general. Eye image acquisition, finding of the eye pupil ROI (Region Of Interest), compression of ROI and its wireless transmission in compressed form over a medium are very beginning steps of the entire eye tracking algorithm targeted on finding coordinates of human eye pupil. Therefore, it is necessary to reach the highest performance possible at each step in the entire chain. In contrast with state-of-the-art general-purpose image compression systems, it is possible to construct an entire new eye tracking application-specific image processing and compression methods, approaches and algorithms, design and implementation of which are the goal of this thesis

Research in eyeball tracking technique has been developed for decades, and has been commercialized. Besides being continuously used in scientific experiments, such as discussing the reaction of human vision toward to different colors or shapes, or analysis one’s psychology state. Some of its applications include: alternative input devices in human-machine interface or recording of the vision of eyes. However, most of the eye-tracking devices have the same defects: complicated calibration procedures and the accuracy are easily affected by head motion. Therefore, it hasn’t been widely used up to now. In this thesis, author have designed and developed a pupil tracking system which can track with high speed and acquire the location and motion of pupil. This system has twice calculate speed then the previous generation, and much more accurate. Two kinds of artificial eye have been developed driven by servo motor and shape memory alloy. The one driven by servo motor can be control precisely, and the other one with shape memory alloy designed according to human extra-ouclar muscle can operate under low voltage and current quietly. In thesis, we construct a system for evaluating the pupil tracking system with optical system objective.

In this thesis, we discuss several methods of eye status detection for close eye alert systems. The proposed close eye alert system based on tracking eye states was implemented. If the system detects the close eye state, it will show a warning message to alert. The proposed system contains two parts: the eye tracking and the eye state detection. Firstly, we pre-process original facial images for future easier processing due to some noises in images. We use several methods to do the pre-process, which are described as follows: 1. Convert the color space to the YCbCr format, 2. Use the mean filter to smooth the images, 3. The Sobel filter is used to get the edges of images, 4.Use “Self Quotient Image” algorithm to remove influences of different light conditions, and then we use different sizes of templates to detect the possible candidate area of eyes. Next, we propose four methods to detect the eye states, which are described as follows: 1. Use the skin color base on the threshold of the Cr color, 2. Use the skin color base on the normalized RGB pixels, 3. Use the search window to find out the minimum gray-level value, 4. Use the cross filter to find out the minimum gray-level value. Thus, we can get the close eye states by comparing the color variations of the first image with that of the present image. In our experiments, we use a personal computer with 2.66GHz Quad-core CPUs for simulations. There are up to 15 video clips in the video database for four different individuals, which includes: the clips for frontal view without glasses, the clips with frontal view and wearing thin rim glasses, the clips for frontal view and black frame glasses, and the clips with upward view without glasses. The experimental results show that our methods can detect the eye states in various situations, such as wearing glasses. Under the premise that eyes are open at the first frame, compared with the other methods, the proposed method by using the search window has better detection accuracy for the eye state detection on non-glasses situations, and the proposed method by using the cross filter has better detection accuracy for the eye state detection on glasses situations.

This research designs the new structure of ultrasonic piezoelectric ceramic actuator to develop a robotic eye. Three main components of the robotic eye are an eyeball holding video CCD, four piezoelectric ceramics driving the robotic eyeball to rotate on two axes and a polygonal seat including four magnets to preload the piezoelectric ceramic. The structural concept of robotic eye is developed to drive and sustain the eyeball with the piezoelectric actuators and to create a contact-less force loading on the actuator with the magnet, besides, to overcome the mechanical constraint of one axis corresponding to one degree of freedom, and to shrink the proportion of the realization. The structural design is based on the force equilibrium to calculate the preload on a actuator in a cross configuration due to the direct magnetic force and the force resulting from the eccentric moment of the weight of robotic eyeball in the robotic eyeball rotating. The analyzed result shows that the four piezoelectric cubes and the four magnets are set the positions at sixty degrees and thirty degrees respectively, and 13.4 N of the magnetic forces at 4 mm of the air gap should make the preload of each piezoelectric cube preserve 8~9 N. Finally, the project sets up the prototype and the structural design technologies of the robotic eye.

Fisheye lens are the ultra wide-angle lens with the view angle larger than 180 degrees. By applying non-similar imaging principle, fisheye lens could introduce negative distortion to have ultra wide view angle imaging onto a limited image plane. To design proper fisheye lens with 0.3M pixel sensor for the vehicle camera, the current study utilizes reverse telephoto lens as the foundation, combining with optical design software to deal with the aberration comes with the negative distortion. After structural analysis and aberration convergence simulation, the proposed lens were composed by a four-piece compound material lens, including one piece of glass and triplet aspheric plastic lens. The total length of the proposed lens is 11.9mm, which is significantly reduced from the current five-piece lens with 16.5mm in length. In addition, the lesser relative distortion could be achieved by adopting the ultra-short focus design concept. The 0.8mm effective focal length makes a relative distortion of only -50% at 150 degree view angle, while the current lens with effective focal length of 1.34mm would cause a relative distortion of -70%. When the proposed fisheye lens are functioned with 1/4" CMOS image sensor, the 192 degree of horizontal field view angle could be achieved to ensure the coverage of panorama images. The Modulation Transfer Function at the maximum field reaches 0.347 when the cutoff frequency of system is 90lp/mm, which ensures the image quality at the edges of the panorama image.

Objective:Age-related macular degeneration (AMD) and retinitis pigmentosa (RP) are two of the leading causes of blindness due to the degeneration of retinal photoreceptors. Artificial eye is one of the ways which may restore sight for the people who are blind caused these diseases. Studies showed that proper visual signals may be restored by effectively stimulating bipolar or ganglion cells through implanted electrodes in retina. Method:There are two major approaches of retinal stimulation in the visual prosthesis: sub-retinal and epi-retinal configurations. Each of them has its advantages and bottlenecks in performance. That leads us to bring out a new idea which may overcome the defects that have been existed in these two types of prosthesis and improve the overall performance: the sandwich-type approach. According to the structural algorithm, the sandwich-type should provide higher image resolution and lower power consumption than the two previous configurations. This research is focused on the parameters setting associated with the stimuli of current amplitude and duration for what we need in the sandwich-type approach. Thus to achieve this purpose the type of the retinal chip should equip with photo-sensitive device on it. This main structure of the retinal chip can be divided into several parts which contain photodiode, signal processing circuits and electrodes. The mechanism of this testing chip is that using photodiode as light sensor which transfers light intensity to current amplitude so that it can reflect the gray level of an image. Incorporated with the followed control circuit in the chip, which the stimulus parameters are preset, the light intensity in the form of current amplitude is delivered to the designed particular electrode of the electrode-array. Then the bipolar or ganglion cells in retina can be properly stimulated for the purpose of vision restoration. Result:Two generations of retinal chips had been designed with single and double power supply individually in this study. Linearity test of current output showed with pretty good results for the two chips. The maximum output current for the first chip is 496�嫀 with LSB of 16�嫀, and 88�嫀 with LSB of 2.8�嫀 for the second one. Conclusion:In this study the designated chip was using the process of TSMC 0.35�慆 Mixed-Signal 2P4M CMOS to implement the functions which the parameters of the output biphasic currents containing amplitude, pulse width, duration, period, frequency of stimulation in a period and selection of the electrode can be programmable. In the future, if the photodiode can be replaced by a form of high density array, the system design of this kind of chip might become more complex, but it should be more fulfilled with the physiological function in the reality of biology.

Advertising designer how to use layout design to communicate with consumer became the important issue. For this reason this study investigated the eye movement to research effects of layout design of advertisement on Eye Movements. Include 2 experiments. Exp1 investigated the effects of advertisement layout on eye movements and comprehension. A layout has four quadrants. There were four contents in an advertisement: figure, title, text, and message. There were six kinds of combination for presenting title, text and message in different quadrants when the picture was presented in a given quadrant. Advertising character display had two levels : vertical type, horizontal type. A total of thirty two graduated college students participated in the experiment. Results showed that the effects of presentation order (in different quadrants) for title, text and message significantly affected subject’s average fixation duration, mean pupil size and accurate rate, average saccade amplitude, fixation account, saccade account and advertising picture also significantly affected subject’s average fixation duration and mean pupil size. And Text display significantly affected subject’s average fixation duration, average saccade amplitude, accurate rate, blink account, saccade account. Exp2 investigated the effects of picture of advertisement, character size, and line spacing on eye movements. the figures size had three levels:56 cm2, 84 cm2, 112cm2. The character size had three levels:12pt, 14pt, 16pt. The line spacing had three levels:18pt, 21pt, 24pt. Three independent variables are within-subject factors. Analyses showed character size significantly affected subject’s fixation count, average fixation duration, saccade count, and average saccade amplitude, mean pupil size. Line spacing significantly affected subject’s average fixation duration and average saccade amplitude. Picture size significantly affected subject’s mean pupil size. Moreover, two interactive two-way effects were found: size of picture advertising × line spacing and size of picture advertising × character size. The present findings could be used as a practical reference in the design of advertisement.

Eyes, known as the window of the soul, are the important medium for getting information from the world. Life becomes extremely inconvenient if one loses his/her eyesight. Fortunately, researchers found that some eye diseases could be cured in the foreseeable future, particularly for the blindness which was caused by the damaged photoreceptors. Hence, by implanting the microelectrodes into the retina and effectively stimulating the bipolar or ganglion cells of the eyes, the sight could be restored. Up to now, there are two main ways of the visual prosthesis: sub-retinal, and epi-retinal approaches. Each of them, however, has its merits and demerits, thus it is difficult to tell which one is better. In order to improve the overall performance, we have brought up a new idea—the sandwich-type approach, which is surpassing for its high resolution and low power consumption. We hereby name the implantable visual prosthesis “retina chip,” and the whole system “artificial eye.” An artificial eye contains imaging sensor, wireless transmitter, retinal chip, and microelectrodes. The retinal chip, as the theme of this thesis, is made up of two parts. Stimulus waveform controller is the first part, which is implemented by CPLD(Complex Programmable Logic Devices), whose code is composed of amplitude controller, timing parameter, biphasic logic, and scanning controller. Biphasic current stimulator, the second part, is implemented by ASIC(Application-Specific Integrated Circuit), whose circuit is composed of digital to analog converter, cascoded current mirror, demultiplexer, and biphasic controller. The considerations of this design are safety, effectiveness, economy, and practicability. The experimental results have met the desired specifications. With 1 KΩ retinal load, the retina chip can generate the programmed stimulus waveform, operating at the frequency up to 5 MHz with good linearity. The differential nonlinearity is less than 0.6 LSB and the integral nonlinearity is less than 2.1 LSB. The maximum output of the biphasic current is 620 uA with 20 uA step. It can also sequentially stimulate 16 channels to make up frames. Compared to the other related reports, we find that the sandwich-type approach has better resolution and lower power consumption, thus the overall performance can be improved.

The objective of this thesis is to the integrate of CCD cameras and a robotic arms as a visual servoing system ,using for the grab for a object. The visual servoing system is mainly based on the position-based control and the image-based control. The architecture of this system is based on the concept of position-based control. In order to accomplish the framework of the system, it is divided into four parts: a vision system, the control of the robotic arm, the search for objects, and the grab systems for objects . The vision system is used to detect the edge of objects and find their locations through the method of Robert edge detection after collecting the information of colors. The control system of the robotic arm aims at calculating the angles of each axis after replacing the control panel with PC. Path planning and PD controller are introduced to obtain a better movement. The search of objects is adopted to solve the problem of the range of vision. The grab for objects is used to solve the problem of inconsistency on timing between the movement of robotic arms and robot vision process.

Self-care is the behavior in which people administer medication and care for themselves in order to maintain their health. Self-care behavior has become increasingly common. The use of over-the-counter medications is derived from the concept of self-care. Because such medications may be accessible to and taken by family members of various age groups, medication packaging is a crucial factor influencing drug use intentions. The purpose of this study is to focus on evaluating current eye drops packaging design and to improve design in order to meet Visual Universal Design (VUD) principles. This study was conducted in four stages. In the first stage, the packaging design of eye drops currently sold on the market was analyzed. In addition, an eye-drop purchaser thinking and behavior survey was conducted to determine their medication needs and habits, and collect the potential concerns they have with eye-drop packaging. In the second stage, according to the collected concerns and 10 visual universal design criteria, specific evaluation indicators were established for examining eye-drop packaging. In the third stage, three design improvement schemes were implemented according to the deficiencies and design specifications of eye-drop packaging summarized in the second stage. In the fourth stage, the three schemes were evaluated and verified according to the visual universal design criteria. The following concludes packaging redesign project: (1) Having concrete improvement plans by following VUD principles; (2) Improve color and pictures on current packaging; (3) By having professional and user friendly eye-drop packaging design, it is not only benefit elderly, but also younger population.

People see the scenery over the world through their eyes, however, many eye diseases would congenitally or gradually affect the vision. Today RP and AMD are two of the most common diseases for retina. Artificial eye is a way to restore some sight for the blind people in whom the photoreceptors have already degenerated. Wireless transmitter is the most important part which can decide the stability in the whole system. Kinds of ways to transmit image signals from external unit in artificial eye are the wire type and the wireless type. Traditional transmission systems connected by wires are easier to design and have higher stability, but they have danger of infection. Contrary, the wireless way will not be infected but cause some problems in systematic complexity, complexity and correctness of channel coding, limitation of frequency band and systematic power, and bioheat effect from long-term receiving electromagnetic wave. In this study we used a class-E power amplifier and coil to transmit energy and data. Then we designed received circuits and fabricated the phantom of an eye based on parameters of the retinal chip. The temperature change was measured in the phantom and evaluated for the conditions of energy attenuation and temperature variation in different distances. And finally, we got a new design consideration for future studies.

In this high tech generation, virtual spaces for commercial and personal usage are now gradually affecting our daily lives through the connection with internet platform, like shopping, cloud, video conference, online games, and so on. Nowadays, there are more and more research and products that trying to build the bridge between real life and virtual space. Therefore, the idea of virtual reality and augmented reality is the outcome of connecting real world and virtual concepts. So far, whether immersing in the virtual world or moving the virtual image to the real word, head-mounted display has being continuously innovated. The next generation of head-mounted display should be light, equipped with wide viewing angle, high resolution, instant 3D image, and more comfortable user experience. In fact, these are the issues head mounted displays now encounter. Therefore, in this thesis, we proposed a new type of near eye display which apply light filed technology to achieve the features of light and simple structure and comfortable for wearing. We used Sony 0.7” OLED as the display in our research and designed the parameters for the system as well as discussed about how the different parameters would affect the imaging quality. We first proposed a thick lens ray tracing algorithm to correct the ray-tracing error of elemental image in traditional pinhole ray-tracing algorithm so as to enhance imaging quality and available to be applied in real situation. In the meantime, a freeform micro-lens array was designed to solve the blurry image issue at large field of view. We then did the analysis on imaging quality and field of view, etc. The results show that compared with the conventional system using spherical micro-lens array, the effective field of view in our system is 4.5 times larger under the premise that the highest theoretical resolution is not reduced. We successfully designed a lighter head mounted display compared with the conventional one and improved the blurry image issue in large field of view in conventional light field display. We also did the tolerance analysis to evaluate the probability of production. In the future, we wish to apply light field head mounted display to more areas such as education, medical training, entertainment, commercial and etc.

Optical design and experimentation with optical simulation software has become an important step in the industrial production of optical components.It can reduce manpower calculation time, error rate,know the merits of the system before and reduce the waste generated by the error. With the software growing stronger, precision and accuracy also increased significantly. VR(Virtual Reality) and Ar(Augmented- Reality) is the most popular things in nowadays.Both of them are supported by near-eye imaging techniques. In this paper,I use the optical software witch called Tracepro to design near-eye matrix display.I use lattice of light source point in this experiment, fold the optical path by reflector. Between the waveguide and the light source,use lens to adjustment. The waveguide set to 3mm.Let light is total reflected in waveguide.And use microstructure to break total reflection. In the experiment, the imaging defects and the size of the field of view (FOV) to make adjustments. To keep the quality of imaging as a prerequisite, to increase the near-eye imaging size as the main purpose of the research purposes. In the physical experiments, the plastic material (photosensitive resin) produced by 3D printing, but also greatly reduce the cost of the factors.
