Publication number: 20230398433Abstract: A DVS has an array of light-sensitive elements in a known configuration and outputs signals corresponding to events at corresponding light-sensitive elements in the array in response to changes in light output from two or more light sources in a known configuration with respect to each other and with respect to a controller body. The signals indicate times of the events and array locations of the corresponding light-sensitive elements. Filters selectively transmit light from the light sources to light-sensitive elements in the array and selectively block other light from reaching those elements and vice versa. A processor determines a position and orientation of the controller from times of the events, array locations of corresponding light-sensitive elements, and the known light source configuration and determines a position and orientation of one or more objects from signals generated by two or more light-sensitive elements resulting from other light.Type: ApplicationFiled: June 10, 2022Publication date: December 14, 2023Inventors: Xiaoyong Ye, Yuichiro Nakamura

Publication number: 20230400915Abstract: A tracking system uses one or more light sources to direct light toward one or more of a user's eyes. A dynamic vision sensor (DVS) operably coupled to a processor is configured to view the user's eyes. The DVS has an array of light-sensitive elements in a known configuration. The DVS outputs signals corresponding to events at corresponding light-sensitive elements in the array in response to changes in light from the light sources reflecting from a portion of the user's eyes. The output signals include information corresponding to locations of the corresponding light-sensitive elements in the array. The processor determines an association between each event and a corresponding particular light source and fits an orientation of the user's eyes using the determined association, the relative location of the light sources with respect to the user's eyes and the locations of the corresponding light-sensitive elements in the array.Type: ApplicationFiled: June 10, 2022Publication date: December 14, 2023Inventors: Xiaoyong Ye, Yuichiro Nakamura
