Hardware components and experimental equipment for the prototype system. (A) 3D motion capture-based light-touch system for experiments 1 and 2. IR marker attached to the subject’s trunk and fingertip with virtual force computation based on subject motion. The computer also generates stimulation signals for fingertip feedback. (B) Wearable light-touch device used for experiment 3. The subject’s motions are monitored using the fingertip acceleration sensor. Virtual forces are determined on a microcomputer based on acceleration, and fingerpad feedback is provided in line with motion. A webcam is used to record subject movement.
