Abstract
Pervasive Computing (PerComp) research remains to this date technology-centric, requiring more focus on utilizing human and societal intelligence. To bridge this gap we motivate the need for a conceptual framework that provides a vision for enabling end-users to participate actively in the design of PerComp applications. The framework in particular provides guidance for the development of tools that allow end-users to configure their own smart environments. It emphasizes the benefits of using Smart Objects (SOs) as components of PerComp applications under a system engineering perspective and the benefits of using affordances as dynamic connectable capabilities under a user experience perspective. A generic application model is developed within the framework that manifests the concepts governing the structure and operation of applications composed by connecting SOs together and adhering to a rule-based behavior. A multi-layered software mediator is defined to provide a platform for the runtime support of such PerComp applications. Theoretical foundations for the key concepts adopted regarding the interaction design and system engineering perspectives are discussed and the results of a user evaluation study focusing on the perceived usability of the high-level conceptual models and the developed tools are reported.
