Abstract
The present application discloses systems and methods for a virtual input device. 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.
