This is unbelievably sick:
Finding the keypad on your cellphone or music player a bit cramped? Maybe your forearm could be more accommodating. It could become part
of a skin-based interface that effectively turns your body into a touchscreen.
Called Skinput, the system is a marriage of two technologies: the ability to detect the ultralow-frequency sound produced by tapping the skin with a finger, and the microchip-sized “pico” projectors now found in some cellphones.
The system beams a keyboard or menu onto the user’s forearm and hand from a projector housed in an armband. An acoustic detector, also in the armband, then calculates which part of the display you want to activate.
