Towards Requirements Analysis and Assessment of Pervasive Systems

Context-Aware Pervasive Systems (CAPS) are dynamic and heterogeneous software applications that focus on the collaborative use of computing devices available in the physical environment of users. In this paper, the authors present a CAPS specification model that is used to specify context features and their dynamic interactions in the physical environment of users. CAPS specification model presents the notation of 'Context chunk' to specify system-to-be features and associated rules for dynamic configuration under changing environments.
