Skinput Turns Your Arm Into a Touchscreen (W/ Video)

Working in conjunction with Microsoft, a researcher at Carnegie Mellon University’s Human-Computer Interaction Institute has developing an innovative new interface that turns users bodies into a control surface. Called “Skinput”, the system consists of an armband-mounted video projector and a series of bio-acoustic sensors. Due to variations in skin, muscle and bone density, the sounds captured by these sensors can be used to determine where on the users arm a given tap was made.
