Abstract
Waveguide-based beacon configurations for tracking, for example, virtual reality (VR) controllers, are disclosed. In some implementations, a device may include a light emitting diode, a waveguide, and an optical element. The waveguide may be formed within a frame of the device for a virtual reality headset. The optical element may be configured to couple a light from the light emitting diode into the waveguide. The waveguide may be configured to emit at least a portion of the light out of the waveguide as multiple beacons for tracking an orientation and a displacement of the device.
Claims20
A device including:
- a light emitting diode;
- a waveguide formed within a frame of the device for a virtual reality headset;
- and
- an optical element configured to couple a light from the light emitting diode into the waveguide, wherein the waveguide is configured to emit at least a portion of the light out of the waveguide as multiple beacons for tracking an orientation and a displacement of the device.
A controller for a user interface in a virtual reality headset, comprising:
- a handling feature to provide a grip for a user of the virtual reality headset;
- a frame to support multiple beacons for tracking the controller by the virtual reality headset;
- and
- a device that includes the beacons within the frame, wherein the device includes a light emitting diode, a waveguide, and an optical element configured to couple a light from the light emitting diode into the waveguide, and wherein the waveguide is configured to emit at least a portion of the light out of the waveguide as the beacons for tracking an orientation and a displacement of the controller.
