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 a 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: A method of tracking movement of an eye of a user includes directing a light beam at the eye. The eye may reflect a portion of the light beam. The method further includes detecting a plurality of speckle patterns formed at a detector by the portion of the light beam reflected by the eye. The plurality of speckle patterns may be detected at a predetermined frame rate. The method further includes tracking movement of the eye by tracking the plurality of speckle patterns from frame to frame.

Abstract: An image display system includes an optical subsystem configured to emit a first light beam and a second light beam, wherein the first light beam illuminates a first portion of a composite field of view and the second beam illuminates a second portion of the composite field of view. A scanning mirror is positioned to intercept and reflect the first light beam and the second light beam. The system also has a waveguide with at least one input coupling optical element for receiving the first light beam and the second light beam into the waveguide. The waveguide also has an output coupling optical element for projecting a plurality of output light beams derived from the first light beam and the second light beam from the waveguide to illuminate the composite field of view.

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: 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.
