Google Glass patent hints at laser projected keypad on your hand

Laser-projected keyboards have been around forever. But laser keyboards projected onto the palm of your hand from Google’s Project Glass? That’s new.
In most cases, blinks, nods and voice control will be sufficient for taking photos and sharing them to Google+ and such. However, Google might have a solution for more advanced forms of input.
A new Google patent filed on June 26, 2012, but only recently made public suggests the $1,500 glasses may use a camera and projector to project a virtual keyboard on your hand.
