  • Patent number: 9800846
    Abstract: Hand gestures may be performed to control a visual projector. When a human hand is placed into a projection field of the visual projector, the visual projector responds to hand gestures performed by the human hand. The human hand, for example, may gesture to rotate a projected image or to correct the projected image. The visual projector may thus manipulate and/or correct the projected image in response to the gesture performed by the human hand.
