COMBINED LIGHT INTENSITY BASED CMOS AND EVENT DETECTION SENSOR FOR HIGH SPEED PREDICTIVE TRACKING AND LATENCY COMPENSATION IN VIRTUAL AND AUGMENTED REALITY HMD SYSTEMS

To facilitate control of an AR HMD, a camera unit in a camera sensor system generates RGB/IR images and the system also extrapolates images for times in the future based on light intensity change signals from an event detection sensor (EDS) for HMD pose tracking, hand tracking, and eye tracking. The times in the future are provided by an HMD application which defines the future times, and the RGB/IR images and extrapolated images are sent back to the application. In this way, the camera sensor system enables improved performance tracking (equivalent to using very high-speed camera) at lower bandwidth and power consumption.
