Context-Awareness Meta-model for User Interface Runtime Adaptation

Effective adaptation of User Interfaces (UI) is still a main requirement to improve system usability and enhance the user experience. The heterogeneity in contexts of use augmented the complexity of such a task. Several requirements should be accommodated in order to meets users’ expectations. Design time adaptations are no more sufficient to guarantee context awareness. A user satisfaction’s shortcoming is still revealed backed by the lack of support of user’s preferences and interventions at run-time, which decreases user-centeredness and usability. In order to improve the UI contextualization and user-centeredness, deeper research on how to adapt efficiently and effectively the UI at runtime should be directed. This paper proposes a Context-Awareness Model (CAM) that consists of modeling UI, context and adaptation by addressing user’s involvement at runtime. The CAM model is aimed to support user interface designers to develop and conceptualize system that accommodate context-awareness, and user-centeredness requirements.
