Abstract: A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the HMD. For example, the HMD-to-eye alignment vary for different users and may change over time (e.g., as a given user moves around or as the HMD slips or otherwise becomes displaced). The wearable device may determine a relative position or alignment between the HMD and the user's eyes. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, may provide feedback on the quality of the fit to the user, and may take actions to reduce or minimize effects of any misalignment.

Abstract: Systems and methods are disclosed for low motion-to-photon latency for augmented and virtual reality systems. Some systems generate rendered frames that are presented to a user by outputting light from a head-mounted display unit. The rendered frames are perceived by the user as virtual content. The head-mounted display unit includes an orientation sensor, a display configured to output light to the user, and processors. The processors receive a rendered frame of virtual content, obtain orientation information from the orientation sensor, and warp or modify the rendered frame of virtual content based on changes to the orientation of the user's head. The warped rendered frame is subsequently outputted from the display using modulated light. The processors and the orientation sensor may be part of a spatial light modulator for modulating the light used to present the warped rendered frame. In addition, the spatial light modulator may be a LED array having low persistence and a high duty cycle.

Abstract: Embodiments of the present disclosure relate to continuous and/or binocular time warping methods to account for head movement of the user without having to re-render a displayed image. Continuous time warping allows for transformation of an image from a first perspective to a second perspective of the viewer without having to re-render the image from the second perspective. Binocular time warp refers to the late-frame time warp used in connection with a display device including a left display unit for the left eye and a right display unit for the right eye where the late-frame time warp is performed separately for the left display unit and the right display unit. Warped images are sent to the left and the right display units where photons are generated and emitted toward respective eyes of the viewer, thereby displaying an image on the left and the right display units at the same time.

Abstract: A dynamically actuable diffractive optical element (DOE) includes a substrate and a diffraction grating disposed on a first region of a surface of the substrate. The DOE further includes a quantity of a fluid disposed on a second region of the surface of the substrate, a fluid displacer disposed adjacent the second region of the surface of the substrate, and a drive signal source configured to send an electric signal to the fluid displacer. The fluid displacer is configured to, upon receiving the electric signal in a first state, causing a portion of the quantity of the fluid to be displaced from the second region of the surface into grooves of the diffraction grating, and upon receiving the electric signal in a second state, causing the portion of the quantity of the fluid to retract from the grooves of the diffraction grating to the second region of the surface.

Abstract: A display subsystem for a virtual image generation system comprises a planar waveguide apparatus, an optical fiber, at least one light source configured for emitting light from a distal end of the optical fiber, and a mechanical drive assembly to which the optical fiber is mounted as a fixed-free flexible cantilever. The drive assembly is configured for displacing a distal end of the optical fiber about a fulcrum in accordance with a scan pattern, such that the emitted light diverges from a longitudinal axis coincident with the fulcrum. The display subsystem further comprises an optical modulation apparatus configured for converging the light from the optical fiber towards the longitudinal axis, and an optical waveguide input apparatus configured for directing the light from the optical modulation apparatus down the planar waveguide apparatus, such that the planar waveguide apparatus displays one or more image frames to an end user.

Abstract: An augmented reality (AR) device is described with a display system configured to adjust an apparent distance between a user of the AR device and virtual content presented by the AR device. The AR device includes a first tunable lens that change shape in order to affect the position of the virtual content. Distortion of real-world content on account of the changes made to the first tunable lens is prevented by a second tunable lens that changes shape to stay substantially complementary to the optical configuration of the first tunable lens. In this way, the virtual content can be positioned at almost any distance relative to the user without degrading the view of the outside world or adding extensive bulk to the AR device. The augmented reality device can also include tunable lenses for expanding a field of view of the augmented reality device.

Abstract: Techniques are described for operating an optical system. In some embodiments, light associated with a world object is received at the optical system. Virtual image light is projected onto an eyepiece of the optical system. A portion of a system field of view of the optical system to be at least partially dimmed is determined based on information detected by the optical system. A plurality of spatially-resolved dimming values for the portion of the system field of view may be determined based on the detected information. The detected information may include light information, gaze information, and/or image information. A dimmer of the optical system may be adjusted to reduce an intensity of light associated with the world object in the portion of the system field of view according to the plurality of dimming values.
