A Framework for User Interface Adaptation to Emotions and their Temporal Aspects

Designing and adapting user interfaces (UIs) based on context and individuals' dynamic characteristics is essential to improve user experience and performance. Emotions are a significant aspect of users' characteristics since they lead to certain behaviors. Consequently, adopting emotions in UI adaptation is a crucial task for developers. However, it is difficult considering the various characteristics of emotions, particularly their variability and temporal aspects. This paper presents a framework for UI adaptation covering specific dimensions of emotions and their temporal aspects. More specifically, the mechanism permits UI adaptation to i)different types of emotions categorizations (basic emotions, facial action units, and arousal/valence) and ii) timing (duration) based on different emotions consolidation. Examples from a serious game prototype illustrate the proposed adaptation mechanisms.
