PrePrint: Three R's of Cyber-Physical Spaces

Three R's of Cyber-Physical Spaces

Recognition, reasoning and retrieval are three fundamental operations in a cyber-physical space that is capable of identifying and tracking the movements of people and answering questions about their whereabouts. We show that a state transition system effectively abstracts the three R's: events abstract recognition, transition function abstracts the reasoning, and states abstract the information necessary for performing retrieval. We provide quantitative metrics for the performance of a cyber-physical space by refining the standard information-theoretic measures of precision and recall. This article also presents performance improvements from integrating spatio-temporal reasoning with biometric-based recognition.
