hypnosec writes: Google has filed for a patent for Methods and Systems for a virtual input device, the idea which was presented back in 2009 at TED by MIT’s Pranav Mistry, a computer scientist. SixthSense, Pranav’s invention, is basically a device that is combination of three major things: camera, projector and a mirror. The device can be instructed to click photos through hand gestures as well project a phone keypad on any surface including hands to dial a number and make a call. The virtual keypad is shown in the photograph above. Pranav also holds a patent of such a device (US 2010/0199232) and can be seen presenting the device here. This is the idea that Google seems to have nicked from A to Z. In the patent application, Google has explained in the patent application that through the virtual input device a pattern can be projected on a hand and users can select items from the virtual pattern through the opposite hand.
