PAWMOJI: Emotionally Expressive Avatar for the Quantified Pet Users / PAWMOJI: En emotionellt uttrycksfull avatar för husdjursägare som vill kvantifiera sina husdjurs beteendenMarasligil, Mehmet Faik January 2018 (has links)
The primary aim of this study is to investigate the impact of an avatar to dog’s daily pet care for the quantified pet users. Furthermore, it explores the design challenges of creating a dog-like avatar for Human-Pet-Computer Interaction. Pawmoji, an emotionally expressive avatar, was designed as a supporting element on the interface to help users interpret the data and increase motivation. Pawmoji changes emotional states according to pet’s daily activities. The data from the device is conveyed to the user via changes in the emotional state of the avatar. This concept was evaluated by pet activity tracker users. In the evaluation, users interpreted the presented emotions of the dog-like avatar in a similar way to human emotions and generally identified the needs of their dogs with high accuracy. The study has also identified design challenges, such as representation and message delivery, and revealed the potential impact of the avatar in daily pet care activities: unpleasant emotions displayed by the avatar were found to be less motivating by the participants. The study shows that an emotionally expressive avatar has the potential to motivate the dog owners and increase awareness of the dog’s state and feelings during the pet-caretaking process. / Det primära syftet med den här studien är att undersöka en avatars påverkan på hundägares husdjursvård för den kvantifierade användaren. Vidare, en emotionell uttrycksfull hundliknande avatar skapades för att fungera som ett designkoncept. Pawmoji ändrar emotionella tillstånd i förhållande till djurets uppmätta aktiviteter. Data från enheten transporteras till användaren genom förändringar i avatarens emotionella tillstånd. Konceptet utvärderades genom en aktivitetsspårare för husdjur. I utvärderingen tolkade deltagarna känslorna som presenterades av den hundliknande avataren, på samma sätt som en människas känslor kan observeras och kunde generellt sett identifiera hundens behov med hög precision. Studien har också identifierat designutmaningar som framställning och mottagning av meddelande och upptäckte den potentiella påverkan avataren har i dagliga aktiviteter för husdjursvård: Obehagliga känslor som presenterades av avataren ansågs vara mindre motiverande för deltagarna. Studien visar att en emotionell uttrycksfull avatar har potentialen att motivera hundägarna och öka medvetenhet om hundens tillstånd och känslor under processen av djurskötning.

Validation d’une vidéo d’animation pour l’évaluation visuelle de l’hémianopsie homonymeFerreri, Jeff 08 1900 (has links)
Mémoire de maîtrise présenté en vue de l'obtention de la maîtrise en psychologie (M. Sc) / Contexte : L’hémianopsie homonyme (HH) a un impact significatif sur les activités quotidiennes, et les méthodes actuelles d’évaluation des personnes ayant une amputation du champ visuel ne permettent pas de combiner l’évaluation de la vision centrale et périphérique. Objectifs : Cette étude visait à valider un film d’animation innovant comme nouvel outil d’évaluation pour mesurer l’étendue du champ visuel aveugle, à établir une norme auprès d’une population contrôle en bonne santé visuelle et à déterminer le niveau de faisabilité du test. Méthodologie : La vidéo d’animation présentait une série de personnages à détecter. Elle était présentée sur 160° répartis sur 3 moniteurs d’ordinateur. Un eye-tracker était utilisé pour vérifier la stabilisation de la tête et le contrôle de la fixation. Quarante participants en bonne santé, âgés de 18 à 75 ans, ont été recrutés. Résultats : La plupart des animations ont été perçues par des participants contrôle sains, ce qui a permis d’établir une norme pour le test. Concernant l’appréciation du test, 60 % des participants l’ont beaucoup apprécié, 29 % l’ont aimé et 11 % ont eu une opinion neutre. Conclusion : Cet outil écologique évalue simultanément la vision centrale et la vision périphérique à l’aide d’un film d’animation. Avec des normes établies à partir d’une population générale ayant une vision saine et un accueil positif des participants, cet outil pourrait être utilisé pour évaluer et dépister les personnes suspectées d’avoir une HH, en particulier chez les enfants. / Background: Homonymous hemianopia (HH) has a significant impact on daily activities, and current methods of assessing people with visual field amputation don’t combine assessment of central and peripheral vision. Objectives: The aim of this study was to validate an innovative animated film as a new assessment tool for measuring the extent of the blind visual field, to establish a standard in a visually healthy control population, and to determine the test’s feasibility. Methodology: The animated video presented a series of characters that needed to be detected. It was presented in 160 degrees on 3 computer monitors. An eye tracker was used to check head stabilization and fixation control. Forty healthy participants aged between 18 and 75 were recruited. Results: Most of the animations were perceived by healthy control participants, helping to establish a standard for the test. In terms of appreciation of the test, 60% of participants liked it a lot, 29% liked it and 11% had a neutral opinion. Conclusion: This ecological tool simultaneously assesses central and peripheral vision using an animated film. With standards based on a general population with healthy vision and a positive reception from participants, this tool could be used to assess and screen people suspected of having HH, particularly in children.

EMPIRICAL COMPARISON OF THE STATISTICAL METHODS OF ANALYZING INTERVENTION EFFECTS AND CORRELATION ANALYSIS BETWEEN CLINICAL OUTCOMES AND SURROGATE COMPOSITE SCORES IN RANDOMIZED CONTROLLED TRIALS USING COMPETE III TRIAL DATAXu, Jian-Yi 10 1900 (has links)
<p><strong>Background:</strong> A better application of evidence-based available therapies and optimal patient care are suggested to have a positive association with patient outcomes for cardiovascular disease (CVD) patients. Electronic integration of care tested in the Computerization of Medical Practices for the Enhancement of Therapeutic Effectiveness (COMPETE) Π study showed that a shared electronic decision-support system to support the primary care of diabetes improved the process of care and some clinical markers of the quality of diabetes care. On the basis of COMPETE Π trial, COMPETE Ш study showed that older adults at increased risk of cardiovascular events, if connected with their family physicians and other providers via an electronic network sharing an intensive, individualized cardiovascular tracking, advice and support program, enhanced their process of care – using a process composite score to lower their cardiovascular risk more than those in conventional care. However, results of the effect of intervention on composite process and clinical outcomes were not similar – there was no significant effect on clinical outcomes.</p> <p><strong>Objectives:</strong> Our objectives were to investigate the robustness of the results based the commonly used statistical models using COMPETE III dataset and explore the validity of the surrogate process composite score using a correlation analysis between the clinical outcomes and process composite score.</p> <p><strong>Methods:</strong> Generalized estimating equations (GEE) were used as a primary statistical model in this study. Three patient-level statistical methods (simple linear regression, fixed-effects regression, and mixed-effects regression) and two center-level statistical approaches (center-level fixed-effects model and center-level random-effects model) were compared to reference GEE model in terms of the robustness of the results – magnitude, direction and statistical significance of the estimated effects on the change of process composite score / on-target clinical composite score. GEE was also used to investigate thecorrelation between the clinical outcomes and surrogate process composite scores.</p> <p><strong>Results:</strong> All six statistical models used in this study produced robust estimates of intervention effect. No significant association between cardiovascular events and on-target clinical composite score and individual component of on-target clinical composite score were found between the intervention group and control group. However, blood pressure, LDL cholesterol, and psychosocial index are significant predictors of cardiovascular events. Process composite score can both predict the cardiovascular events and clinical improvement, but the results were not statistically significant- possibly due to the small number of events. However, the process composite score was significantly associated with the on-target clinical composite score.</p> <p><strong>Conclusions:</strong> We concluded that all five analytic models yielded similar robust estimation of intervention effect comparing to the reference GEE model. The relatively smaller estimate effects in the center-level fixed-effects model suggest that the within-center variation should be considered in the analysis of multicenter RCTs. Process composite score may serve as a good predictor for CVD outcomes.</p> / Master of Science (MSc)

Design of a GPS Tracker Housing for Cattle / Design av ett GPS tracker-hus för nötkreaturFredriksen, Isabelle January 2024 (has links)
This Bachelor’s thesis, carried out by Isabelle Fredriksen at Blekinge Institute of Technology in collaboration with Embedded Art, aims to developa robust and user-friendly GPS tracker housing for cattle. The projectfocuses on improving livestock management through real-time monitoringand health surveillance, aiming to enhance animal welfare and operationalefficiency on farms. The project aims to design an innovative GPS housing that ensures secureattachment in a collar around a cow’s neck. It also seeks to optimize material selection for durability and minimal signal loss, as well as to develop anopening mechanism that protects internal components from environmentalimpacts. The project followed a structured product development processconsisting of a preliminary study, requirement specification, concept generation, concept evaluation, concept development, prototype development,and final evaluation. Through interviews and market surveys, importantrequirements for the product were identified, including ergonomic design tominimize stress and discomfort for the animals, as well as durable materialsthat can withstand various weather conditions. Three different design concepts were developed and evaluated. Several design iterations were assessed through a combination of practical tests oncattle and technical experiments, including tests for water resistance andsignal strength. The final design resulted in a modular housing, optimizedfor prolonged use without frequent maintenance. It includes a tightly sealing lid and robust fastening to ensure water resistance and protection ofinternal components. For future work, additional material testing should be performed to ensurethe final material choice is optimal for the intended environment. There isalso potential to integrate solar cells to extend battery life and reduce theneed for frequent battery replacements.

A Hardware-In-The-Loop Star Tracker Test BedHaraguchi, Ashley 01 June 2024 (has links) (PDF)
As the use of small satellites for advanced space missions continues to grow, the importance of low mass and cost three-axis attitude stabilization systems increases as well, with these systems requiring high accuracy attitude knowledge. Star trackers provide the most accurate attitude knowledge of any type of attitude sensor, but the high cost, size, and weight of commercial star trackers can be prohibitive to small satellite missions. Many simple star trackers have been developed using commercial off-the-shelf camera sensors and processing hardware, but the challenge remains in testing and characterizing these devices. A common solution is night sky tests, in which the star tracker is held up to the night sky to image the star field and perform attitude determination. Commercial star trackers, on the other hand, are regularly tested with manufacturer provided star field images that attach directly to the sensor. These methods, however, severely limit the sky conditions that can be used in testing. Night sky tests depend on weather and can only image regions of the sky the user has access to, while lab-based testing uses the few provided still images. This thesis presents a hardware-in-the-loop star tracker test bed developed for comprehensive ground-based testing of both in-house and commercial star trackers. The system consists of a small screen to display a star field, a simple in-house camera star tracker, and a microprocessor. This test bed allows any star field image to be simulated. The system is set up for use on a stationary tabletop, but its small size lends itself for use with a spacecraft dynamics platform, which can facilitate testing of control algorithms using real star tracker output.
