This thesis explores the intersection of Artificial Intelligence (AI) and User Experience (UX)design, aiming to leverage AI capabilities to enhance the overall user experience designprocess. The research included user interviews, data collection, and the usage of AI toolsto enhance efficiency. The collaboration with a company provided insightful informationand directed the research toward investigating AI capabilities in UX design. The studyclarifies the advantages of AI design tools, their impact on the UX design procedure, and thepossibility of further developments. It ends by introducing the AIUX app concept, whichprovides a streamlined and collaborative approach to UX design. The results highlightthe significance of a balanced approach, where AI enhances rather than replaces humancreativity and invention. As AI technology develops quickly and is increasingly included indesign tools, this thesis offers a starting point for further study.

[pt] Este estudo propõe fazer uma análise sobre o impacto da experiência de Realidade Aumentada (RA) aplicada no varejo online utilizando dispositivo móvel. Após a revisão de literatura feita sobre este tema, foi elaborado um modelo e foram formuladas hipóteses que permitissem investigar a relação entre a Experiência de Realidade Aumentada e a Intenção de Compra, sendo esta relação mediada por avaliações do consumidor, tais como, Certeza na Escolha, Satisfação do Usuário e a Emoção Positiva. Para testar o modelo, foi feito uma pesquisa com 201 consumidores. Os dados coletados foram analisados pelo método de modelagem de equações estruturais (SEM) e confirmaram a maioria das hipóteses formuladas, apresentando relações significativas dos construtos mediadores que ficam entre a Experiência de Realidade Aumentada e a Intenção de Compra. Os resultados indicam a importância da avaliação feita pelo consumidor sobre a Certeza na Escolha ao utilizar uma Experiência de Realidade Aumentada antes da Intenção de Compra. É oportuno mencionar que o construto Emoção Positiva também é um mediador significativo entre a Experiência de Realidade Aumentada e a Intenção de Compra, porém menos forte que a Certeza na Escolha. Estes resultados sugerem que os consumidores, após uma Experiência de Realidade Aumentada, são levados a avaliar os aspectos cognitivos e afetivos antes da decisão pela compra. / [en] The purpose of this study is to analyze the impact of Augmented Reality (AR) experiences applied to online retails using a mobile device. After reviewing the literature on this topic, a model was elaborated, and hypotheses were formulated to investigate the relationship between the AR experience and the purchase intention. This relationship is mediated by consumer evaluations, such as certainty in the choice, user satisfaction, and positive emotions. To test the model, a survey was conducted with 201 consumers. The collected data were analyzed using the structural equation modeling method and confirmed most of the formulated hypotheses, presenting significant relationships between the mediating constructs with the AR experience and with the purchase intention. The results indicate the importance of the evaluation made by the consumer on the certainty of the choice when using an AR experience before the purchase intention. It is worth mentioning that the positive emotion construct is also a significant mediator between the AR experience and the purchase intention, but less strong than the certainty in the choice. These results suggest that consumers, after an AR Experience, are led to assess cognitive and affective aspects before purchase intention.

<p dir="ltr">Managing a forest presents many challenges for tree farmers, especially when relying on traditional manual methods. Previous research highlights the wide range of tasks involved in forest management, from planting and nurturing trees to harvesting and selling timber. These conventional approaches often result in inefficiencies and unexpected difficulties at various stages. However, advances in technology, specifically through the use of LiDAR-based reconstruction and differential geometry, have made it feasible to accurately measure tree sizes and identify species with a single capture.</p><p dir="ltr">To help tree farmers overcome these challenges, this thesis proposes the development of a cross-platform solution named WoodWiz. WoodWiz comprises two synergistic components: a mobile application for real-time, on-site tree measurements, and a web-based platform for comprehensive forest management. The measurement feature in mobile app streamlines the data collection process, reducing time and labor, while MyForest offers a detailed view of the forest's status, facilitating efficient management and planning. Additionally, WoodWiz includes a Library feature, providing a repository of forestry resources and best practices, and a community platform to foster collaboration and knowledge sharing among forestry professionals. This integrated system simplifies the wide range of tasks involved in forest management—from planting and nurturing to harvesting and selling timber—thereby reducing inefficiencies and addressing the unexpected difficulties typically associated with traditional methods.</p><p dir="ltr">The development of WoodWiz involved extensive research, design, and evaluation, culminating in a robust tool that not only streamlines forest management tasks but also provides tree farmers with actionable insights for decision-making. By automating critical measurements and facilitating data access, WoodWiz improves the accuracy of forest inventory and health assessments, leading to more informed and strategic management practices. The potential impacts of this solution on the forestry industry include increased productivity, improved sustainability of forest resources, and enhanced profitability for tree farmers. This thesis details the iterative process of WoodWiz's development, highlights its key features, and evaluates its effectiveness in transforming forest management practices.</p>

The purpouse of this study is to find out how and if a Content Managment System (CMS) can benefit from applied User Experience Design (UX). A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it.

Ce projet de recherche vise à explorer le rôle du design dans l’acte d’achat et l’évaluation des produits. L’hypothèse de recherche repose sur le fait que le design est un obstacle à la rationalité dans le choix d’un bien, car ce dernier est rattaché à des singularités qui lui sont propres, le rendant difficilement comparable aux autres biens d’un même marché. Les produits deviennent difficiles à évaluer et à classer parmi les autres biens similaires dans le marché. En soi, la finalité et les vertus du design permettent aux consommateurs d’avoir une plus grande liberté de choix, mais ce rôle dynamique et économique que peut prendre le design peut aussi confondre les consommateurs devenant brouillés par l’abondance de choix. En ce sens, le design serait la clé de la voûte d’une économie des singularités telle que proposée par Lucien Karpik dans L’économie des singularités. Avec une méthodologie ethnologique, cinq projets d’évaluation de produits au sein de deux organismes produisant des dispositifs d’aide à la consommation ont été observés sur une période de deux ans. À la conclusion de cette étude, il a été démontré que certaines améliorations pouvaient être apportées aux processus d’évaluation, plus particulièrement en ce qui concerne les facteurs qui ne sont pas pris en compte dans les dispositifs d’aide à la consommation actuels, comme l’évaluation de produits centrée sur l’usager à l’aide de scénarios d’usages, plutôt que l’évaluation de produits centrée sur l’objet, ainsi que la considération de l’expérience de l’usager dans l’évaluation des biens. / This research project aims at exploring the role of design within the act of purchasing and rating products. This premise is based on the fact that design is an obstacle to an individual’s rationality when choosing goods because they are multidimensional and of uncertain quality, as proposed by Lucien Karpik. This creates a difficulty faced by consumers when trying to find comparable products on the market. The research hypothesis of this project suggests that design is an obstacle to reason by offering multidimensional products to consumers. It then becomes harder for them to evaluate singular products available on the market, and to make wise consumption choices. One of the aims of design is to offer users freedom of choice, but this dynamic and economic role of design can also lead to confusion, where consumers become blinded by the abundance of choices. In this sense, design would be the keystone of a singularity-based economy. Five product rating projects were observed on a two-year period within two agencies involved in producing consumption aid devices by using an ethnological approach. The conclusion of this study has shown that some improvements could be made to the product rating processes, particularly for the facts that have not been accounted for in the actual consumption aid devices, such as user-centered product ratings based on user scenarios instead of object-centered product ratings, as well as considering user experience in product evaluation.
