    Abstract: A robot eye and two different eye tracking systems may be used in tandem to determine the accuracy of eye tracking software that is used as part of one of the eye tracking systems. If inaccurate, the eye tracking software may then be adjusted in response. In various example embodiments, a camera may be used in one of the eye tracking systems to then track movement of the robot eye using the eye tracking software itself. Also in various example embodiments, the other eye tracking system may include components such magnetic sensors, optical sensors like CMOS sensors, and/or lasers for tracking the same movement of the robot eye.

    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.

    Abstract: 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.
