Resumo(s)
As emoções têm um papel central nas nossas vidas. Influenciam a forma como pensamos e agimos, a nossa saúde e a nossa sensação de felicidade e bem-estar. Estudos recentes demonstram que as emoções desempenham um papel essencial nos processos cognitivos, na criatividade, bem como na saúde física, influenciando o nosso sistema imunitário e a nossa relação com o mundo. Em particular, os avanços científicos e tecnológicos ao nível da neurociência e da informática estão a permitir aumentar o conhecimento e a consciência sobre os processos emocionais, e regular o seu funcionamento. A computação afetiva é um tema de importância fundamental, que tem por objetivo a melhoria da experiência dos utilizadores com os sistemas, recorrendo a estados emocionais. Este trabalho apresenta estudos e desenvolvimentos de mecanismos de avaliação de emoções em resposta a estímulos audiovisuais, usando biossensores, inseridos numa aplicação, com vista a aumentar a consciência emocional e a potenciar a sua regulação em termos de bem-estar. Assim, foi realizado um estudo preliminar sobre o estado da arte e depois um questionário para compreender os usos de media pelas pessoas e o que era mais desejado na aplicação a desenvolver. A aplicação permite a visualização em tempo real dos estados emocionais e do bem-estar, a escolha e navegação em conteúdos multimédia com base em emoções e a análise unificada de valores emocionais. No final, a aplicação foi avaliada com utilizadores, para saber sobre a sua percepção relativamente à utilidade, satisfação e facilidade de uso, eficácia das visualizações e concordância com as emoções detetadas, assim como recolher as suas sugestões e comentários. Os resultados mostraram-se muito positivos: a apreciação geral da aplicação foi que era simples de usar, com um aspecto agradável e com visualizações do estado emocional interessantes, intuitivas e que mapeavam bem as emoções sentidas.
Emotions have an important role in our lives. They influence the way we think and act, our health and our sense of happiness and wellbeing. Recent studies show that emotions are present in cognitive processes, creativity, as well as in physical health, influencing our immune system and our relation with the world. In particular, scientific and technological advances related to neuroscience and informatics are enabling additional knowledge and consciousness about the emotional processes, and regulate their functioning. Affective computing is a subject of main importance, which aims to improve the user’s experience with the systems, using emotional states. This work presents the study and development of emotion evaluation mechanisms in response to audiovisual stimuli, using biosensors, inserted in an application, in order to increase the emotional awareness and aim for its regulation in terms of wellbeing. Therefore, a preliminary study was performed about the state of the art and afterwards a questionnaire was applied to understand the use of media by people and what was more desired to include in the application to develop. The application allow the real-time visualization of the emotional states and wellbeing, the selection and navigation through multimedia contents based on emotions and the unified analysis of emotional values. In the end, the application was evaluated with users, to learn about perceived usefulness, satisfaction and ease of use, the efficacy of visualizations and agreement with detected emotions, as well as to hear about their suggestions and comments. The results turned out be very positive: the global appreciation of the application was that it was easy to use, with a pleasant look and feel and visualizations based on emotional states which were interesting, intuitive and with a good mapping of felt emotions.
