Abstract
A tracking system uses a dynamic vision sensor (DVS) operably coupled to the processor. The DVS has an array of light-sensitive elements in a known configuration. The DVS outputs signals corresponding to two or more events at two or more corresponding light-sensitive elements in the array in response to changes in light output from two or more light sources mounted in a known configuration with respect to each other and with respect to a controller. The output signals indicate times of the events and locations of the corresponding light-sensitive elements. The processor determines an association between each event and two or more corresponding light sources and fits a position and orientation of the controller using the determined association, the known configuration of the light sources and the locations of the corresponding light-sensitive elements in the array.
