Perceptual functions for context-awareness of an office worker

Symbiotic Computing is a kind of research project and concept to bridge the gap between Real Space (RS) and Digital Space (DS). The purpose is mainly to develop flexible information service or application as well as to establish the next generation information platform. In order to establish the framework, it is necessary to build 'Mutual Cognition' between human and system. Mutual Cognition broadly consists of two functions; 'RS Cognition' and 'DS Cognition'. This paper focuses on RS Cognition, which is perceptual function of software system for some events or human's activities. In this study, we develop two perceptual functions, which are sitting posture recognition and human's location recognition for an office worker, as a kind of RS perception task. As the results of experiments, we found that our developed functions are quite competent to recognize worker's activities.
