bioSync: Synchronous Kinesthetic Experience among People

This paper presents synchronous kinesthetic interaction among people. The users are able to perceive muscle activity bi-directionally, such as muscle contraction or rigidity of joints, through somatosensory channels in a realistic manner. We have developed a wearable haptic I/O device, named bioSync, that equips a developed electrode system for enabling the same electrodes to perform biosignal measurement and stimulation. We conducted a pilot study to evaluate the optimal forms of a feeding spoon for people with neuromuscular disorders by reproducing muscle tremors in healthy people. Potential scenarios for achieving interactive rehabilitations and sports training are also described. It is essential for both the trainers and the learners to perceive not only the physical bodily motions but also the muscle activity.
