While we are very excited about Google’s Project Glass, the best method of controlling it is still open to debate. Google is very serious with expanding its Project Glass capabilities. What we have here is a good example of that. They are now applying to patent a virtual touchpad projected onto limbs and other everyday surfaces, specifically in relation to the project.



The system will use a small laser projector mounted on the arm of the glasses to beam out keyboard and other buttons, the built-in camera and the processor will try to interpret finger movements in the region of those buttons.

Sounds neat. All they need is a way to recognize the finger movements without requiring the user to actually look towards the projected image.
