The much awaited augmented reality glasses, Project Glass, by Google, which is set to be launched for public in 2014, is seeing another major addition to its already impressive spec kitty, with Google filing for a patent for a laser projected keyboard which can be tapped at by fingers . The patent entitled "Methods and Systems for a Virtual Input Device" includes the fact that unlike as shown in the pic above, this virtual keyboard could be used on any surface, with a camera and projector doing all the work.
Also worth noting is the fact that the patent also includes the projection of various kinds of keyboards, including a QWERTY and a numeric one. Though it is not for sure to be included in the final AR spec, knowing Google's tendency to experiment a lot. But a lot can be hoped from this, and the final Project Glass as a whole!
