  • AR/VR controller with event camera
    Patent number: 10845601
    Abstract: In one implementation, a method involves obtaining light intensity data from a stream of pixel events output by an event camera of a head-mounted device (“HMD”). Each pixel event is generated in response to a pixel sensor of the event camera detecting a change in light intensity that exceeds a comparator threshold. A set of optical sources disposed on a secondary device that are visible to the event camera are identified by recognizing defined illumination parameters associated with the optical sources using the light intensity data. Location data is generated for the optical sources in an HMD reference frame using the light intensity data. A correspondence between the secondary device and the HMD is determined by mapping the location data in the HMD reference frame to respective known locations of the optical sources relative to the secondary device reference frame.
