This paper presents a novel wearable kinesthetic I/O device that achieves blending kinesthetic interaction among people. The users are able to perceive muscle activity bi-directionally, such as muscle contraction or rigidity of joints, by connecting users' body. The kinesthetic information is exchanged between users through somatosensory channels by biosignal measurement and stimulation. We have developed a wearable haptic I/O device, called bioSync, that equips a developed electrode system for enabling the same electrodes to perform biosignal measurement and stimulation at 100Hz. Potential scenarios using kinesthetic synchronization include interactive rehabilitation and sports training. It is essential for both the trainers and the learners to perceive not only the physical bodily motions but also the muscle activity. The methodology, performance evaluations, user studies and potential scenarios are described in this paper.
