The gaming industry is changing, and new games and gaming experiences are being developed. From board games to video games, to the latest AR and VR games. Right now, developers are trying to develop experiences that combine the real and the virtual into one wholesome and believable mix. This gives new opportunities to implement technology in classical artifacts. In the context of board games there are several tangible pieces, and the dice is the chosen main character for this study. Placed in the middle, between board games and digital games, AR games comes now. Previous research of board games and digital technology gives interesting information on the activity and provides a foundation for new design. The dice is world famous, so this study aims to find out how this piece can evolve with the help of technology. By working with concept driven design, in relation with an AR game studio, the AR Dice and the AR Game DiceFold was invented. A qualitative method was used in which experts of the industry got together to discuss the new experiences of AR games and the functionality of the AR Dice which might become a new part of the gaming world in the near future. The findings of this study lead to three promising discoveries. A new gaming component, new AR game and further answers regarding research in the scopes of AR games. / Spelindustrin förändras och nya former av spel och upplevelser utvecklas. Från brädspel till datorspel till de nyaste AR och VR spelen. Just nu arbetar utvecklare med att skapa nya upplevelser där det virtuella kombineras med verkligheten till en fulländad och trovärdig mix. Detta skapar utrymme för nya möjligheter at implementera teknologi i klassiska artefakter. Inom kontexten av brädspel finner vi många fysiska spelobjekt och tärningen är vald som huvud-karaktären för den här studien. Placerad mellan brädspel och digitala spel kommer nu AR spel. Tidigare forskning inom brädspel och teknologi gav intressant information inom kontexten och agerar som riktlinjer och som grund för ny design. Tärningen är världskänd så siktar den härstudien mot att ta reda på hur det här objektet kan utvecklas med hjälp av teknologi. Genom att arbeta med konceptdriven design och i nära relation med en AR spelstudio, designades den nya AR tärningen och det nya AR spelet DiceFold. En kvalitativ metod användes där experter inom industrin diskuterade de nya möjliga upplevelser inom AR spel och funktionaliteten hos AR tärningen, som kanske kan bli en ny del inom spelvärlden i en snar framtid. Denna studie resulterar i tre olika saker, den nya spel komponenten AR tärningen, det nya AR spelet DiceFold och mer information inom forskning av AR spel.

This thesis deals with the improving of website business performance through the optimization with a focus on user experience. Its concern is not how to accumulate more traffic to the website but rather how to motivate website users, persuade and help them achieve desired goals. The aim is to introduce the concept of User Experience (UX) and Conversion Optimization (CRO). Further on, to suggest a general process of the website optimization focused on user experience and to apply this procedure in a case study. The contribution of this thesis is to link the UX/CRO concepts that provide users with a positive brand experience and allow organizations a sustainable competitive advantage, differentiation and higher marketing ROI.

The aim of this diploma thesis is to create a practical solution for individual athletes in the form of a digital mirror, which can become an alternative to observing yourself in an ordinary mirror. The work contains and emphasizes the benefits of a digital mirror. Much of the work is devoted to the transfer of video between various devices for the ability to combine multiple videos on a single screen. The core of the solution is a mobile application for the Android platform, which works in various modes, the choice of which depends on how the application is used. The application was continuously tested with a group of users, resulting in iterative improvements to the application's features and the addition of new features. Furthermore, a web variant of the application was implemented, which increases the possibility of using the digital mirror across different platforms. The results of testing show that this whole solution can be used in the practical training of sports exercises and the application has the potential to connect with various sports.

[pt] A comercialização de roupas on-line impõe alguns desafios para quem as compra e para quem as vende, pois tratam-se de produtos com os quais as pessoas ainda sentem a necessidade de ter um contato físico. Alguns de seus atributos são dificilmente comunicados digitalmente como a textura e o caimento do tecido. Soma-se a isto a falta de padronização de tamanhos praticada pela indústria de vestuário e o resultado é um cenário que sucita diversas dúvidas no consumidor/usuário. Objetivou-se com esta dissertação elaborar diretrizes que possam contribuir com o design de sítios de comércio eletrônico de vestuário feminino mais eficientes, eficazes e satisfatórios, proporcionando uma experiência do usuário (user experience em inglês, originando a sigla UX) positiva. Alguns métodos e técnicas foram usados em duas fases: a pesquisa exploratória e a descritiva. A fase da pesquisa exploratória foi constituida por uma entrevista exploratória, um questionário on-line e uma entrevista com especialistas de moda. Foi possível constatar que o maior problema enfrentado pelos consumidores/usuários ao comprar peças de roupas on-line está relacionado às medidas e à vestibilidade das peças. Além de ser um problema de usabilidade, por induzir os usuários ao erro, verificou-se que seu impacto maior era sobre a experiência do usuário uma vez que pode criar uma expectativa negativa em relação a interação com o sistema. Na fase da pesquisa descritiva os usuários foram divididos em dois grupos e solicitados a realizar um teste de usabilidade em um sítio de comércio eletrônico selecionado para avaliar sua interação ao comprar peças de roupas. Um grupo utilizou um desktop/laptop e o outro um smartphone. Ao finalizar as tarefas os usuários eram solicitados a responder a um debriefing e ao questionário AttrakDiff2. Por fim os dados obtidos foram analisados e os resultados dos testes realizados nos dois dispositivos (desktop/laptop e o outro um smartphone) comparados a fim de avaliar se houve diferenças na UX. Observouse que existe uma falta de conhecimento técnico por parte de usuário em relação aos atributos das peças de roupas, eles não sabem identificar os tipos de tecido e sentem-se extremamente inseguros quanto às informações de medidas fornecidas pelas empresas. Existe uma falha na comunicação destes atributos na medida que não são apresentadas de uma forma que facilite o seu entendimento pelos usuários seguindo os seus modelos mentais. Não confirmou-se uma diferença significativa na UX ao comparar a interação com os dois tipos de dispositivos. Ao final desta dissertação, são listadas diretrizes para aprimorar a UX ao interagir com sítios eletrônicos que comercializam peças de vestuário. / [en] Selling clothes online poses some challenges for those who buy them and for those who sell them, they are products with which people still feel the need to have a physical contact. Some of its attributes are not easily communicated digitally as the fit and the feel of a fabric. Besides, the lack of standardization of sizes practiced by the clothing industry results in a scenario that raises several doubts to the consumer/user. The objective of this dissertation is to elaborate guidelines that may contribute to the design of more efficient, effective and satisfactory female e-commerce websites, thus providing a positive user experience (UX). Some methods and techniques were used and sorted into two stages: an exploratory and a descriptive research approach. The exploratory research consisted of an exploratory interview, an online questionnaire and an interview with fashion specialists. It was possible to verify that the biggest problem faced by the consumers/users when buying clothes online is related to sizing and the wearability of the pieces. In addition to being a usability problem, by inducing users to errors, it was noted that its greatest impact was on the user experience as it can creat a negative expectation regarding the interaction with the system. To carry out the descriptive research, the users were divided into two groups and asked to do a usability test on a selected e-commerce website in order to evaluate their interaction when buying clothes. One group used a desktop/laptop and the other a smartphone. At the end of the test, the users were asked to respond to a debriefing and the AttrakDiff2 questionnaire. Finally, the data was analyzed and the tasks carried out on the two devices (desktop / laptop and the other a smartphone) were compared in order to evaluate if there were differences in the UX. It has been found that there is a lack of technical knowledge on the part of the user regarding the attributes of clothing, the users do not know how to identify fabric types and they feel extremely insecure about the size information provided by the retail companies. The website fails to communicate these attributes in a way that facilitates the understanding by users and that follows their mental models. There was no significant difference in UX when comparing the interaction on the two types of devices. At the end of this dissertation, there is a list of guidelines elaborated with the objective to improve the UX on female fashion websites.
