New Technology Allows You to Dial Numbers On Your Arm

 PhD Student Chris Harrison has created a new system that allows touchscreen interaction on hairy and uneven surfaces – like skin."Omnitouch" is a wearable system that "enables graphical, interactive, multitouch input on arbitrary, everyday surfaces." Images can be projected on walls, tables, and, yes, hands.

But don't take our word for it. Check out the video below for a look at this impressive system in action:
