Google applies for laser projection system patent.
A new patent application from Google describes “Methods and Systems for a Virtual Input Device”. When combined with Google Glass, the system allows a virtual control panel to be projected onto a users hand or arm, with a camera monitoring movement on the surface which it interprets as inputs.
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. In another example, the camera may detect when the display hand is moving and interpret display hand movements as inputs to the virtual input device, and/or realign the projection onto the moving display hand.
Google has been known to be working on several different ways of controlling their augmented reality glasses, including having a small control panel on one side, or sensors on the arm of the glasses able to sense and interpret hand movements without actually touching the device.
