Abstract
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.
