Trust is one of the attitudes that can affect the intentions and the behavior of a human using a system. Misusing a system can have safety- as well as economic consequences, this is why it is important that a user develops calibrated trust towards a system. In this report, the research question is: how much trust cross country skiers have towards a physical intelligent tutoring system (PITS)? Six biological males (age 24 to 50) roller skied on a mechanical treadmill and received feedback from the PITS on a TV-screen. Experience of using the PITS was evaluated with an instrument in a semi-structured interview. The instrument measured the participants overall perceived trust (OPT) for the system, and the participants were asked to further their thoughts about the statements. The data was transcribed, coded, and categorized in a thematic analysis. The result showed that a majority of the participants had low OPT for the PITS, and the thematic analysis showed that the minority with higher levels of OPT focused on the choice of an elite skier as the reference skier. One of the problems with the instrument was that it was developed for evaluation in long term usage, and not first time usage as in this study. The result of this report can be used for further development of the PITS and a reminder on why trust needs to be considered when creating user experiences.

However, access to information through these devices is a new challenge of interaction for users who have some kind of disability. Currently, most mobile applications have accessibility barriers that make it difficult or impossible the usage for many individuals with special needs. To ensure access to the content to all users regardless of their health status, this paper proposes a model for evaluating user interfaces accessibility focused on mobile devices. The proposed model takes into account the users experience without neglecting the specificities of mobile context and accessibility scenario. As a result, there is a group of perceptions observed from the tests performed to evaluate the three mobile applications developed for deaf. As a contribution, there is a group of recommendations for the evaluation of the user experience and the challenges and new perspectives to evaluate the mobile accessibility, given that few methods consider these two contexts in a coupled way. / O uso de dispositivos móveis traz grandes benefícios de conectividade para seus usuários. Contudo, o acesso à informação através desses dispositivos representa um novo desafio de interação para os usuários que possuem algum tipo de deficiência. Atualmente, a maioria das aplicações móveis possui barreiras de acessibilidade que dificultam ou impossibilitam sua utilização por diversos indivíduos com necessidades especiais. Visando garantir o acesso ao conteúdo a todos os usuários, independentemente de limitações físicas e mentais, este trabalho propõe um modelo de avaliação de interfaces de usuário voltado à acessibilidade em dispositivos móveis. O modelo proposto leva em consideração a experiência de usuários sem deixar de lado as especificidades do contexto móvel e do cenário de acessibilidade. Como resultados, tem-se um conjunto de percepções observadas a partir de testes realizados ao avaliar três aplicações móveis desenvolvidas para surdos. Como contribuição, tem-se um conjunto de recomendações para avaliação da experiência de usuários, bem os desafios e novas perspectivas ao avaliar a acessibilidade móvel, dado que poucos métodos consideram de forma acoplada esses dois contextos.

abstract: This dissertation explores the role of smart home service provisions (SHSP) as motivational agents supporting goal attainment and human flourishing. Evoking human flourishing as a lens for interaction encapsulates issues of wellbeing, adaptation and problem solving within the context of social interaction. To investigate this line of research a new, motivation-sensitive approach to design was implemented. This approach combined psychometric analysis from motivational psychology's Personal Project Analysis (PPA) and Place Attachment theory's Sense of Place (SoP) analysis to produce project-centered motivational models for environmental congruence. Regression analysis of surveys collected from 150 (n = 150) young adults about their homes revealed PPA motivational dimensions had significant main affects on all three SoP factors. Model one indicated PPA dimensions Fearful and Value Congruency predicted the SoP factor Place Attachment (p = 0.012). Model two indicated the PPA factor Positive Affect and PPA dimensions Value Congruency, Self Identity and Autonomy predicted Place Identity (p = .0003). Model three indicated PPA dimensions Difficulty and Likelihood of Success predicted the SoP factor Place Dependency. The relationships between motivational PPA dimensions and SoP demonstrated in these models informed creation of a set of motivational design heuristics. These heuristics guided 20 participants (n = 20) through co-design of paper prototypes of SHSPs supporting goal attainment and human flourishing. Normative analysis of these paper prototypes fashioned a design framework consisting of the use cases "make with me", "keep me on task" and "improve myself"; the four design principles "time and timing", "guidance and accountability", "project ambiguity" and "positivity mechanisms"; and the seven interaction models "structuring time", "prompt user", "gather resources", "consume content", "create content", "restrict and/or restore access to content" and "share content". This design framework described and evaluated three technology probes installed in the homes of three participants (n = 3) for field-testing over the course of one week. A priori and post priori samples of psychometric measures were inconclusive in determining if SHSP motivated goal attainment or increased environmental congruency between young adults and their homes. / Dissertation/Thesis / Ph.D. Design 2013

Time keeps on changing our perception of what is possible in our personal life and around us. Over time, jobs such as elevator operator was essential to make the elevator keep its speed, stop parallel to the floor and keep passengers safe in case of emergency. Nowadays elevator passengers just have to enter their destination and wait to be transported there. An operator would be superfluous for this, today, simple procedure. This paper aims to create a set of interaction strategies to provide an efficient and pleasurable journey for the passenger traveling with an autonomous bus, as well as evaluate concepts where these strategies have been applied. The strategies and concepts will be developed from an extensive user- and literature research where the situation of today will be analysed and looked upon with the eyes of tomorrow, to find challenges and needs. Findings shows that passengers have to trust the vehicle and service. At the same time vehicle and service providers have to provide a reliable and consistent service. Four design directions were created to establish this trust between the user and vehicle and service. To enable control and give passengers an efficient journey, passengers have to be provided with adequate and reliable information. The information regarding the bus’s behaviour should be communicated in a transparent way so the bus’s intentions and actions are understandable from a passenger point of view. Also, passengers have to be enabled to stay safe when using the bus, during commuting and emergency, through giving them cues in how an emergency should be handled.

Using the internet for watching videos or online shopping keeps growing, along with video advertisement to increase online sales. To know if the video actually increases the online sales, the owner of a video ad wants to do follow ups on how the video is doing, and get statistics. A different solution from the original video ads is Smart Video. It is an interactive video player with a clickable slideshow of products. This video can get even more types of statistics than a normal video, and today that statistic is not accessible for the Smart Video clients, without the help of someone from the Smart Video team that can create a report for them. The purpose of this thesis was to relieve the workload of the Smart Video team and to create a dashboard that shows all information that the clients find relevant about their videos. This paper is about the process of developing a design for a marketing dashboard, that follows the guidelines of information dashboard design by Stephen Few. The process included interviews, multiple designs, prototypes, and evaluations, before ending up with a prototype of a desktop solution that follows the aesthetics of Smart Video and can be realizable with the current technology.

Förstärkt verklighet eller Augmented Reality (AR) är idag en av de viktigaste riktningarna inom informationsteknologiområdet (IT). AR-tekniken har redan använts inom områden såsom underhållning, konstruktion, medicinsk behandling, utbildning och är tillgänglig i flera olika enheter som till exempel mobiltelefoner, surfplattor, etcetera. Under de senaste åren har allt snabbare framsteg gjorts inom mobilapplikationer som erbjuder AR-upplevelser, men det finns fortfarande ett behov av en djupare förståelse för hur en bättre användarupplevelse eller User Experience (UX) kan designas i dessa Augmented Reality Mobile Applications (ARMA). Detta examensarbete fokuserar på de aspekter av interaktionen som måste beaktas när ett grafiskt användargränssnitt baserat på ARMA utformas i syfte att göra applikationerna kontextkänsliga. Det betyder att hjälpa användaren få relevant information som passar situationen eller den kontext denne befinner sig in när hen använder sin mobiltelefon och därmed erbjuda hen bättre användarupplevelser. Studien omfattar en heuristisk utvärdering och ett användbarhetstest av mobilapplikationen Layar som bland annat känner igen olika Points of Interest (POI) och som ger direkt digital kontextuell information om dem. Baserat på resultatet av den heuristiska utvärderingen och användbarhetstestet i kombination med tidigare forskning inom området, har åtta stycken designriktlinjer tagits fram. Jag hoppas att dessa riktlinjer kan fungera som ett stöd vid utformningen av gränssnittet på kontextkänsliga ARMA och i förlängningen förbättra användarupplevelsen.

Com a expansão dos serviços digitais por meio de tecnologias móveis na última década observa-se a importância crescente da atitude de design para compreender o contexto de uso e as emergentes necessidades funcionais e emocionais dos usuários nas quais se baseia a percepção de uma boa experiência do usuário (UX). Levando em conta que a estratégia de negócio e a estrutura organizacional são determinantes para o resultado da experiência percebida pelo usuário e o consequente sucesso do serviço, esta pesquisa teve como objetivo principal investigar as práticas de design nas dimensões operacional, tática e estratégica em diferentes empresas prestadoras de serviços digitais tendo em vista a identificação de padrões relacionados com a adoção da gestão de design e da estratégia de design, e qual o impacto desta adoção nas medidas de desempenho. Para isto, foi adotada como estratégia de pesquisa o levantamento teórico preliminar seguido da realização de estudos de casos múltiplos. Neste estudo de caso, foram investigadas empresas com designers e UX designers trabalhando no desenvolvimento de serviços digitais. As evidências compiladas a partir da teoria, combinadas com os padrões obtidos com os casos, resultaram em um modelo de referência sobre a geração de valor através do design, e em quatro proposições teóricas principais que mostram que as práticas de design executadas pelas áreas de experiência do usuário possuem um potencial de integração interdisciplinar e geração de novas ideias propício para melhorar a sinergia e o resultado de uma equipe ágil de projetos, gerando insumo para decisões estratégicas e potencialmente valorizando a determinação de métricas de uso e engajamento. / With the expansion of digital services through mobile technologies viewed on the last decade, it can be observed the growing importance of the design attitude to understand the context of use and the emerging functional and emotional needs of the users on which the perception of a good user experience (UX) is based on. Taking into account that the business strategy and the organizational structure are determinant to the result of the experience perceived by the user and the consequent success of the service, this research had as main objective to investigate the practices of design in the operational, tactical and strategic dimensions on different digital service companies in order to identify the standards related to the adoption of design management and design strategy, and the impact of this adoption on performance measures. Following this purpose, the preliminary theoretical survey followed by multiple case studies was adopted as a research strategy. In this case study, we investigated companies with designers and UX designers working on the development of digital services. Evidence compiled from the theory combined with the patterns obtained with the cases resulted in a reference model on value generation through design, and in four main theoretical propositions that shows that design practices performed by the user experience departments have the potential for interdisciplinary integration and generation of new ideas conducive to improving the synergy and the result of an agile project team, generating input for strategic decisions and potentially valuing the determination of metrics to follow use and engagement.

With the advent of HTML5 as the new standard, web pages became an alternative to native Android and iPhone applications, what made it possible to reduce time and cost of app development and maintenance processes.This thesis is aimed for finding, analyzing and documenting experience and criteria that have weight in a selection of the technology for development of search apps. To achieve this, were developed and compared three alternative client apps (Web-based HTML5, Android and iOS).The results of the thesis provides recommendations for selection the appropriate alternative for the successful development strategy, overview of the problems which may occur during development process, pros and cons of a plain Web-based solution, a Web-hybrid solution, and native Android/iOS solutions that are evaluated for a search intensive apps.

This paper reports a study on the usability of e-commerce accessed through smartphones. There is much research in the usability of mobile interfaces and many sets of design patterns have been created but a few studies are available for specific domains, and in this report we focus on mobile e-commerce. In this study a framework is developed for how to design mobile e-commerce interfaces with a high degree of usability. Furthermore, the study also contributes a method to how other specific domain can develop a framework with general standards to work from when creating a web interface. By examining two sets of design principles and 14 design patterns, we evaluate which ones are critical in the design of a mobile e-commerce interface for achieving a high degree of usability. We have done this by applying the survey in two e-commerce sites with different design approaches to examine how they relate to the selected design patterns and design principles. The survey is conducted in three phases through an online survey, a content analysis and an observational study to investigate the interface usability based on theoretical- and practical perspectives. The study shows that in order to create a good usability of e-commerce sites accessed through smartphones, the user want to recognize themselves in how the content is presented and communicated, as well as the interface should obtain certain key functions.
