Abstract:
Systems and methods for tracking the position of a head-mounted display (HMD). The HMD may include a support structure that carries a forward facing camera and a plurality of optical flow sensor integrated circuits (ICs). The forward camera captures image sensor data in a forward camera field of view (FOV) at a first frame rate, and each of the plurality of sensor ICs captures image sensor data in a respective plurality of sensor IC FOVs at a second frame rate. The sensor IC FOVs may collectively cover at least a substantial portion of the forward camera FOV. A processor may receive the image sensor data from the camera and the plurality of sensor ICs. The processor may process the received image sensor data and/or other sensor data (e.g., IMU data) to track a position of the head-mounted display based on the processing of the received sensor data.
