During the past decades, a substantial amount of research efforts have been made regarding making the web and digital content more accessible. However, research states that the current accessibility state globally is yet not sufficient, resulting in excluding a large group of people due to disabilities. The purpose of this study is to evaluate the current accessibility state of the prototype version of Ubisoft Connect’s chat application and how to make accessibility a natural part of a team's existing agile processes. This is performed by gathering knowledge about a team's current working processes by conducting two qualitative interviews, along with a nine-week observation, allowing us to partake in their processes when implementing changes. To evaluate the chat's current accessibility state, two of the most used usability evaluation techniques are used: heuristic evaluation and user testing. The heuristic evaluation is based on the internationally recognized standard: Web Content Accessibility Guidelines 2.1. The findings from the heuristic evaluation are implemented by the Ubisoft Connect team in the chat prototype and are later tested by 4 testers with disabilities. The result of this case study shows that heuristic evaluation and user testing should be used to complement each other since one method alone cannot create a valid accessibility state. Furthermore, it shows that agile management is the preferred method when making these changes.

The emergence of generative AI and platforms like ChatGPT has revolutionized the industry, triggering a widespread shift towards integrating AI models into various software applications. The Swedish Defence Research Agency is exploring the development of AI assistants for military planning. This thesis investigates the graphical user interface aspects of generative AI assistants. Following initial focus groups, a prototype was developed and assessed through user testing. The findings highlight several crucial elements to consider when designing a user interface for an AI assistant in military planning: user-friendliness, the ability to summarize documents and mission orders, an interactive map accessible to the AI assistant, and an interface to gather data and responses from the AI assistant. Implementing features crucial to the specification is essential when addressing complex tasks involving sensitive and precise data. The broader context of using generative AI represents a rapidly advancing research area that warrants close examination.

The integration of mobile and sensor technologies, and the design and implementation of different web-enabled visualizations to support inquiry learning in different educational scenarios encompass the main research efforts carried out in this thesis. These challenges are addressed from the perspectives of mobile and web engineering, visualization and technology-enhanced learning (TEL). Thus, the main research question investigated in this thesis relates to the identification of the main features that can guide the design and implementation of web and mobile applications to support inquiry learning in different contexts. This thesis consists of a collection of four publications that describe the research efforts conducted during a period of three years in relation to the Learning Ecology through Science with Global Outcomes (LETS GO) research project. The research questions investigated and the implemented technological solutions reported in these publications are closely related to the main goals and challenges of this thesis. The design and implementation of the proposed software system was guided, deployed and refined having the following aspects in mind: (1) System Requirements and Architectural Design, (2) System Implementation and Deployment, and (3) System Assessment and Web Usability Testing. During the three years of development efforts, three software prototypes were implemented utilizing service-oriented approaches. These efforts have been tested with more than 200 users in connection to several trials that took place during this period. The user trials allowed testing the software application throughout three development iterations on authentic settings, while new requirements continuously emerged in these activities. This process made it possible to verify that user requirements were adequately addressed while satisfying their needs. The outcomes of these activities led to the design and implementation of a system architecture that relies on service-oriented approaches and open standards. The main outcomes of this thesis are presented in the form of Architectural Concepts, as they can be used to guide the design and implementation of web and mobile applications to support inquiry learning. The idea behind architectural concepts is to provide a set of tools for supporting the overall life cycle of a software development process, such as requirements, design, implementation, deployment and testing while coping with rapid changes of technological implementations. Some of the architectural concepts identified in this thesis correspond well with the kind of support that inquiry-learning activities require. They provide solid foundations in terms of possibilities to tackle the requirements for supporting inquiry learning in a flexible manner.

Experiência de usuário e experiência de jogador são dois conceitos que apresentam similaridades. Ambos envolvem a interação de um usuário com um produto, havendo sobreposição de métodos e áreas do conhecimento que permitem verificar experiência. Porém há diferenças quanto ao foco dado a experiência resultante da interação. Este trabalho apresenta os conceitos de experiência de usuário, usabilidade, experiência de jogador e jogabilidade apresentados pela literatura. Em seguida é discutido a relação que estas definições possuem entre si, identificando os elementos que os separam, apresentando uma possível divisão entre os conceitos de experiência de usuário e experiência de jogador e suas ferramentas. Ao fim este trabalho apresenta dois experimentos que mostram uma forma de verificar experiência de jogador em dois jogos distintos, procurando a inclusão desses métodos dentro do ciclo de desenvolvimento de jogos. Este trabalho também apresenta uma compreensão sobre experiência de jogador na interação com jogos e a inclusão de sua avaliação dentro do ciclo de desenvolvimento utilizando testes com usuários. / User experience and player experience are two concepts that have similarities. Both involve the interaction between user and product, with overlapping methods and areas of knowledge to evaluate experience. But there are differences as to the focus given to the experience resulted from the interaction. This paper first introduces the concepts of user experience, usability, player experience and playability presented in the literature. Subsequently, it discusses the relationship that these definitions have to each other, identifying the elements that separate them, presenting a possible division between user experience concepts and player experience and tools. Lastly this work presents two experiments seeking to apply the methods to verify player experience in two different games, looking for the inclusion of these methods within the game development cycle. This work presents an understanding on player experience and the inclusion of its evaluation within the development cycle with user-based tests.
