Visualizing physiological condition of two persons during cooperative motion

The purpose of this study is to develop a visualizing system which represents human motion and physiological conditions such as muscle activities, autonomic nervous balances of multi persons simultaneously. Our system generates avatar animation representing muscle activity and heart rate variability of multi persons by color of muscles and heart. Three kinds of assistance motion were visualized to evaluate our system. In these experiments, muscle activity and heart rate variability of assisted and service persons were represented. Physiological conditions of multi persons are presented intuitively using this system. This visualizing system is useful for analysis of workload in cooperative motion.
