Abstract
A hand-held controller for a virtual-reality system includes an antenna, a grip, a cage coupled to the grip, and a plurality of LEDs on an outer surface of the cage. Wireless signals are received from a remote camera via the antenna. The plurality of LEDs is duty-cycled, which includes turning on the plurality of LEDs at times determined using the wireless signals. The times when the plurality of LEDs is turned on correspond to times when the remote camera captures images of the hand-held controller.
Claims20
A method, comprising:
- at a hand-held controller for a virtual-reality system, the hand-held controller comprising an antenna, a grip, a cage coupled to the grip, and a plurality of light-emitting diodes (LEDs) on an outer surface of the cage:
- receiving wireless signals from a remote camera via the antenna;
- and
- duty-cycling the plurality of LEDs, the duty-cycling comprising turning on the plurality of LEDs at times determined using the wireless signals;
- wherein the times when the plurality of LEDs is turned on correspond to times when the remote camera captures images of the hand-held controller.
A hand-held controller for a virtual-reality system, the hand-held controller comprising:
- a grip;
- a cage coupled to the grip;
- a plurality of light-emitting diodes (LEDs) on an outer surface of the cage;
- an antenna to receive wireless signals;
- and
- an LED driver to duty-cycle the plurality of LEDs in accordance with wireless signals received from a remote camera via the antenna.
A hand-held controller for a virtual-reality system, the hand-held controller comprising:
- a grip;
- a plurality of light-emitting diodes (LEDs) positioned to be visible to a remote camera;
- and
- means for duty-cycling the plurality of LEDs in synchronization with image capturing performed by the remote camera.
