A latest patent filing published this week revealed that Google's Project Glass AR specs could be integrated with a laser-projected virtual keyboard, which would allow users to input information by tapping their arm or hand.

Google explained how a virtual keyboard could be used to control the Augmented Reality glasses, expected to go public in 2014. Within the patent, entitled "Methods and Systems for a Virtual Input Device," Google said that the camera and a projector could be used in tandem to facilitate data input on any surface, not just the user's hand.

In the example given, the tiny projector would sit on the arm of the glasses, while the device's camera would be used to interpret the finger strokes and relay that information back to the CPU.

According to the filing, initially made in June last year, "In one example, the virtual input device includes a projector and a camera. The projector projects a pattern onto a surface.”

"The camera captures images that can be interpreted by a processor to determine actions. The projector may be mounted on an arm of a pair of eyeglasses and the camera may be mounted on an opposite arm of the eyeglasses.”

"A pattern for a virtual input device can be projected onto a 'display hand' of a user, and the camera may be able to detect when the user uses an opposite hand to select items of the virtual input device."

The filing also shows how various types of virtual keyboard could be projected onto the surface. In certain circumstances, a full QWERTY keyboard would be employed, while a numeric keypad appears in others.
