Sitting Posture Recognition and Location Estimation for Human-Aware Environment

Abstract

Realization of human-computer symbiosis is an important idea in the context of ubiquitous computing. Symbiotic Computing is a concept that bridges the gap between situations in Real Space (RS) and data in Digital Space (DS). The main purpose is to develop an intelligent software application as well as establish the next generation information platform to develop the symbiotic system. In this paper, the authors argue that it is necessary to build ’Mutual Cognition’ between human and system. Mutual cognition consists of two functions: ’RS Cognition’ and ’DS Cognition’. This paper examines RS Cognition, which consists of many software functions for perceiving various situations like events or humans’ activities in RS. The authors develop two perceptual functions, sitting posture recognition and human’s location estimation for a person, as RS perception tasks. In the resulting experiments, developed functions are quite competent to recognize a human’s activities.

Development of perceptual functions as primitive awareness for VDT work environment

“…As previous work towards symbiotic computing, some perceptual functions have been proposed. For example, sitting posture recognizer and human's location point detector for an VDT worker in the context of telework application [23] [24]. In the previous work, they utilizes optical fiber pressure sensor mattress and acceleration sensor for sitting posture recognition and two USB cameras for location point detection.…”
