Abstract:
A head-mounted device (HMD) is configured to perform head tracking, even in low light environments. The HMD includes a stereo camera pair that includes a first camera and a second camera having overlapping fields of view. Both cameras are mounted on the HMD and are configured to detect both visible light and infrared (IR) light. The HMD also includes a flood IR light illuminator that is configured to emit a flood of IR light that spans an illumination area that overlaps with the cameras' fields of view. The intensity of the IR light is sometimes modified to accommodate low light environmental conditions. The cameras obtain images of reflected IR light. These images are then used to track movements of the HMD, even in low light environments.

Claim (Index 9):
The method of  claim 8 , wherein a second flood IR light illuminator is mounted on the HMD, and wherein the second flood IR light illuminator emits a different flood of IR light.
