Abstract: Techniques are disclosed for performing localization of a handheld device with respect to a wearable device. At least one sensor mounted to the handheld device, such as an inertial measurement unit (IMU), may obtain handheld data indicative of movement of the handheld device with respect to the world. An imaging device mounted to either the handheld device or the wearable device may capture a fiducial image containing a number of fiducials affixed to the other device. The number of fiducials contained in the image are determined. Based on the number of fiducials, at least one of a position and an orientation of the handheld device with respect to the wearable device are updated based on the image and the handheld data in accordance with a first operating state, a second operating state, or a third operating state.

Abstract: A method of tracking an eye gaze include obtaining a pre-calibrated speckle map of the eye of the user, determining a starting position of the eye using the pre-calibrated speckle map, and tracking movement of the eye relative to the starting position by: directing a light beam at the eye, detecting a plurality of speckle patterns formed at a detector by a portion of the light beam reflected by the eye, and tracking movement of the eye relative to the starting position by tracking the plurality of speckle patterns from frame to frame.

Abstract: A head mounted display system can include a camera, at least one waveguide, at least one coupling optical element that is configured such that light is coupled into said waveguide and guided therein, and at least one out-coupling element. The at least one out-coupling element can be configured to couple light that is guided within said waveguide out of said waveguide and direct said light to said camera. The at least one coupling element may comprise a diffractive optical element having optical power. Additionally or alternatively, the at least one coupling optical element may have a coupling area for coupling light into said waveguide having an average thickness in a range from 0.1 to 3 millimeters across and/or may have a slit shaped coupling area.

Abstract: Augmented reality glasses can include a first laser, a second laser, and a scanning mirror. The augmented reality glasses can also include a first polarization selective reflector and a second polarization selective reflector. The first polarization selective reflector is arranged to receive light from the first laser and reflect light received from the first laser at a first angle to the scanning mirror, and the second polarization selective reflector is arranged to receive light from the second laser and reflect light received from the second laser at a second angle to the scanning mirror. The augmented reality glasses can also have an eyepiece having an input coupling port arranged to receive light reflected by the scanning mirror.

Abstract: Augmented reality headgear includes transparent displays that allow a user to simultaneously view the real world and virtual content positioned in the real world and further includes at least one source of coherent light and at least one sensor array for sensing, at a series of times, speckle patterns produced when the coherent light impinges environment surfaces. Circuitry is provided for sensing shifts in the speckle pattern and determining motion which caused the shift of the speckle pattern and adjusting the display of virtual objects displayed by the augmented reality headgear to compensate for the motion.

Abstract: An image display system can include a plurality of light sources configured to emit uncollimated light, and an eyepiece waveguide having an input port configured to receive beams of light at differing angles. The image display system also includes a scanning mirror having a surface with positive optical power configured to receive light emitted by the plurality of light sources. The surface with positive optical power is configured to collimate light emitted by the plurality of light sources to form a plurality of collimated light beams and direct the plurality of collimated light beams to the input port.

Abstract: A head mounted display system can include a camera, at least one waveguide, at least one coupling optical element that is configured such that light is coupled into said waveguide and guided therein, and at least one out-coupling element. The at least one out-coupling element can be configured to couple light that is guided within said waveguide out of said waveguide and direct said light to said camera. The camera can be disposed in an optical path with respect to said at least one out-coupling optical element to receive at least a portion of the light that is coupled into said waveguide via the coupling element and guided therein and that is coupled out from said waveguide by said out-coupling coupling element such that images may be captured by said camera.
