Review of Skinput Technology: Input Through Skin

Skinput technology takes input through the body surface and acts as an interface. So input can be given by tapping a finger on the skin surface. This new input technique is based on bio-acoustic sensing which detects the acoustic signals on the surface of the body as an impact of a finger and this signal propagates through the body. This technology provides input through tapping finger which is naturally portable and contains minimally interfering. The technology is coupled with the bioacoustic detector, sensor, and pico-projectors. An interactive interface can be visible directly on the body surface as a graphical image.
