Item Avaliação Expedita de Livros Falados Digitais(The Eurographics Association, 2021) Pereira, Joana; Carriço, Luís; Carriço, Luís and Correia, Nuno and Antunes, Pedro and Jorge, JoaquimEste artigo versa a aplicação de arquitecturas cognitivas para a avaliação expedita de Livros Falados Digitais. O trabalho, ainda em curso, passa pela identificação das características dessas arquitecturas e dos seus problemas na especificação das variantes de utilizadores e tarefas. Nessa base, pretende-se estendê-las no intuito de permitir uma fácil modelação de utilizadores com diferentes tipos de deficiências e de tarefas normalmente realizadas na utilização desses livros. Pretende-se ainda, através de uma validação comparativa com testes de usabilidade com utilizadores reais, compreender os equilíbrios das capacidades de percepção desse tipo de utilizadores e definir estereótipos de modelos que possam ser usados em avaliações simuladas posteriores.Item Supporting Psychological Therapy with PDAs(The Eurographics Association, 2021) Sá, Marco; Carriço, Luís; Carriço, Luís and Correia, Nuno and Antunes, Pedro and Jorge, Joaquimln this article we present an investigation where the main objective is the implementation of toais that support the diagnosis and therapy process in psychological areas. The interaction issues inherent to this type of process are discussed, and solutions for those issues are introduced, as well as for the management and gathering of data conceming the sarne process, taking advantage of the emerging mobile technologies. New forms of analyzing the results of the diagnosis process, annotation during consultations and creation of the genres used in therapy are also revealed. This article focuses also on the technology necessary for a system such as this and on an overview of what has been dane so far in this field of work.Item Usability Evaluation of Digital Talking Books(The Eurographics Association, 2021) Duarte, Carlos; Carriço, Luís; Carriço, Luís and Correia, Nuno and Antunes, Pedro and Jorge, Joaquimln this paper we present the results of a set of usability evaluation studies on Digital Talking Books. Digital Talking Books aim to provide better access to literary content for the blind and visually impaired. Departing from their digital base, we developed enriched books, targeting broader audiences and usage situations. The books can be enriched with different media content, like images and sounds, supporting multimodal interaction and multimedia presentation. Enlarging the number of interaction possibilities, while making the books more attractive, also increases the possibility of usability problems. This is why it is so important to perform usability evaluation of the generated interfaces. A special focus of the evaluation was given to the synchronization related issues. Synchronization flaws detected by the users were the cause of discomfort and loss of concentration. Alternative synchronization visual marking was employed to circumvent these problems. Tests also provided insight on what modalities are favoured by the users for specific interaction tasks, and confirmed the importance of the availability of multimodal interaction.
