Situation modelling for ambient intelligence: Towards scenario-based methodology and formal presentation of context

A systematic domain study is presented. The analysis was motivated by the aim of domain abstraction and realization of context-aware systems. In an activity-centred approach and based on assumptions from own experiences in the field, the essential parameters about activities and interactions within multimedia presentation scenarios was collected, including Locations, Interactions, Media, Devices, Activities, Environments and Audiance states ( e.g. light and noise setting, user movement, number of persons, level of attention, interruptions). Based on the results of the user study, a context model is proposed.
