摘要： The disclosure relates generally to techniques for determining pupil location of a display device's user via imaging sensors on the display device, and using that information to verify and/or correct positioning of the display device or its internal components. The display device may be a head-mounted display ("HMD") device with display panels separated from a wearer's eyes via intervening lenses, with the sensors including optical flow sensor integrated circuits mounted on or near at least one of the display panels to capture images of the wearer's eye locations through the lenses, and with the correction to the positioning including modifications to the alignment or other positioning of the HMD device on the wearer user's head and/or its internal components within the HMD device (e.g., based on automated control of motors on the HMD device) to reflect a target alignment of the wearer's eyes relative to displayed information.

摘要： 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.

摘要： Systems and methods for providing optical systems which utilize double Fresnel lenses on curved surfaces for use with display systems, such as silicon-based micro display systems (e.g., OLED micro displays) used with head mounted display (HMD) systems. The optical systems disclosed herein may implement multiplexing or blending to provide a smooth profile transition and reduce aberrations between zones or fields (e.g., small FOV angles, large FOV angles) of a Fresnel surface which is defined by multiple Fresnel patterns or functions. An optical system for a micro display is provided which utilizes double Fresnel lenses on curved surfaces to shorten the focal length while maintaining a good shape factor for moldability and aberration control.
