Abstract

Activity recognition (AR) research promises to enable a multitude of human-centric applications in smart environments. Nevertheless, application developers will require assurance mechanisms before they can confidently use and apply AR in real-world pervasive systems. In this work we propose an extension of an existing AR approach in which richer recognition semantics that address confidence and assurance are provided. Our approach differentiates between an activity and its effect and subsequently relies on verifying an activity by recognizing its effect. We present our approach along with a comparative experimental evaluation.
