    摘要： 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.

    摘要： A display subsystem for a virtual image generation system. The display subsystem comprises a planar waveguide apparatus, and an optical fiber having a distal tip affixed relative to the planar waveguide apparatus, and an aperture proximal to the distal tip. The display subsystem further comprises at least one light source coupled the optical fiber and configured for emitting light from the aperture of the optical fiber, and a mechanical drive assembly to which the optical fiber is mounted to the drive assembly. The mechanical drive assembly is configured for displacing the aperture of the optical fiber in accordance with a scan pattern. The display subsystem further comprises an optical waveguide input apparatus configured for directing the light from the aperture of the optical fiber down the planar waveguide apparatus, such that the planar waveguide apparatus displays one or more image frames to the end user.

    摘要： A virtual image generation system (100) for use by an end user, comprising left and right eyepieces (110L, 110R); left and right projection subassemblies (108L, 108R) configured for projecting light into the left and right eyepieces (110L, 110R), such that left and right monocular images are displayed as a binocular image to the end user; a light sensing assembly (122) configured for detecting at least one parameter indicative of a mismatch between the displayed left and right monocular images as the binocular image; a frame structure (102) configured for being worn by the end user and for respectively positioning the left and right eyepieces (110L, 110R) in front of the eyes of the end user; and a control subsystem (114, 116, 118, 120) configured for correcting a mismatch between the left and right monocular images based on the at least one detected parameter detected by the light sensing assembly (122).

    摘要： A virtual image generation system for use by an end user comprises a projection subsystem configured for generating a collimated light beam, and a display configured for emitting light rays in response to the collimated light beam to display a pixel of an image frame to the end user. The pixel has a location encoded with angles of the emitted light rays. The virtual image generation system further comprises a sensing assembly configured for sensing at least one parameter indicative of at least one of the emitted light ray angles, and a control subsystem configured for generating image data defining a location of the pixel, and controlling an angle of the light beam relative to the display based on the defined location of the pixel and the sensed parameter(s).
