    Abstract: Techniques are described for determining a user's unique depth perception in viewing virtual objects in virtual reality (VR) to make the VR experience more accurate and immersive for the user. The user can align a virtual image the user sees with a real-world image behind the virtual image to provide input indicating the user's depth perception. Depth perception parameters can then be determined from that for subsequently rendering VR objects to that user.

    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.

    Abstract: A tracking system and method, comprising a processor; and a controller operably coupled to the processor. Two or more light sources are mounted in a known configuration with respect to each other and with respect to the controller body and the two or more light sources are configured to flash a predetermined time sequence. A dynamic vision sensor is configured to output signals corresponding to two or more events at two or more corresponding light-sensitive elements in an array in response to changes in light output from the two or more light sources and corresponding to times of the two or more events and locations of the events in the light-sensitive elements in the array. The processor determines a position and orientation of the controller from the times and location of the two or more events, and the known information.

    Abstract: A tracking system includes a processor, a controller, two or more light sources and a dynamic vision sensor (DVS). The light sources are of known configuration with respect to each other the controller and turn on and off in a predetermined sequence. The DVS includes an array of light-sensitive elements of 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. The signals indicate times of the events and locations of the corresponding light-sensitive elements. The processor determines an association between each event and one or more of the light sources and, from that association, determines an occlusion of one or more of the light sources. The processor estimates a location of an object using the determined occlusion, the known light source configuration, and the locations of the corresponding light-sensitive elements in the array.

    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.
