Abstract
In this paper, we propose a method of human-to-human skin contact area measurement. Human-to-human skin contact is a primitive communication way to express intimacy, encouragement, etc. Additionally, skin contact is used for therapy of autism, mood disorder, etc. Its quantitative measurement and visualization would contribute for related researches in scientific, medical and physiological fields. Our proposed system utilizes bio-acoustic signals which propagate through bodies. When one wears a vibration device and another wears a vibration sensor device, the sensor captures bio-acoustic waves whose magnitude depends on how large area they touch. We describe design and fabrication of the devices. Then we report about our fundamental experiment and its positive results.
