Emoweb-k: extensão de um plugin para adaptar interfaces de usuário na web considerando emoções

Abstract

Emotions are an important aspect of the user experience when using a system. In the literature, there are works that propose systems that change as user interfaces (UI) considering emotions, taking into account what is felt before or during use. However, no works were found that change the UI, taking into account the emotional state that the user would like to feel. Furthermore, as emotions are easily changed by internal and external events, it is necessary to offer UI that considers and reacts to emotions in interaction time, demanding a flexible software solution. Also, the measurement of emotional state can consider, in addition to the user’s self-expression (subjective feeling), also motor expressions, such as facial movements, and physiological signals, such as heart rate. Obtaining data requires the adaptation of different sensors in different contexts of use, which demands that the computer system have high maintainability. Thus, this undergraduation conclusion work aimed to extend the specific UIFlex plugin to create a flexible infrastructure, with good maintainability, capable of offering UI adaptations in interaction time based on the emotional states that a user feels and desires. to feel. In addition, the software solution was adapted to the IBM MAPE-K blueprint. Versions with and without MAPE-K were compared according to software evaluation metrics. The results suggest that the adequacy to the blueprint brought benefits to the maintainability of the proposed solution.
