電気的筋肉刺激が重量知覚に及ぼす影響の分析

抄録

There are many situations where we are doing simple tasks such as lifting or carrying something in daily life. Several studies have been conducted on supporting method for physical work. These methods have problems about cost and effectiveness. In this paper, we propose weight perception control methods using electrical muscle stimulation (EMS). We investigated the change of weight perception when electrical signals are delivered to the muscles to be contracted in lifting objects. Subjective experiment results showed that subjects perceived objects lighter when electrical signals are delivered to their the biceps brachia muscle or the forearm muscles. It was suggested that our methods are effective for supporting physical work.
