摘要: A system and method are disclosed for detecting angular displacement of a display element relative to a reference position on a head mounted display device for presenting a mixed reality or virtual reality experience. Once the displacement is detected, it may be corrected for to maintain the proper binocular disparity of virtual images displayed to the left and right display elements of the head mounted display device. In one example, the detection system uses an optical assembly including collimated LEDs and a camera which together are insensitive to linear displacement. Such a system provides a true measure of angular displacement of one or both display elements on the head mounted display device.

摘要: Embodiments are disclosed for adjusting alignment of a near-eye optic of a see-through head-mounted display system. In one embodiment, a method of detecting eye location for a head-mounted display system includes directing positioning light to an eye of a user and detecting the positioning light reflected from the eye of the user. The method further includes determining a distance between the eye and a near-eye optic of the head-mounted display system based on attributes of the detected positioning light, and providing feedback for adjusting the distance between the eye and the near-eye optic.

摘要: Methods for tracking the head position of an end user of a head-mounted display device (HMD) relative to the HMD are described. In some embodiments, the HMD may determine an initial head tracking vector associated with an initial head position of the end user relative to the HMD, determine one or more head tracking vectors corresponding with one or more subsequent head positions of the end user relative to the HMD, track head movements of the end user over time based on the initial head tracking vector and the one or more head tracking vectors, and adjust positions of virtual objects displayed to the end user based on the head movements. In some embodiments, the resolution and/or number of virtual objects generated and displayed to the end user may be modified based on a degree of head movement of the end user relative to the HMD.

摘要: Technology disclosed herein automatically focus a camera based on eye tracking. Techniques include tracking an eye gaze of eyes to determine a location at which the user is focusing. Then, a camera lens may be focused on that location. In one aspect, a first vector that corresponds to a first direction in which a first eye of a user is gazing at a point in time is determined. A second vector that corresponds to a second direction in which a second eye of the user is gazing at the point in time is determined. A location of an intersection of the first vector and the second vector is determined. A distance between the location of intersection and a location of a lens of the camera is determined. The lens is focused based on the distance. The lens could be focused based on a single eye vector and a depth image.

摘要: A system and related methods for adaptive event recognition are provided. In one example, a selected sensor of a head-mounted display device is operated at a first polling rate corresponding to a higher potential latency. Initial user-related information is received. Where the initial user-related information matches a pre-event, the selected sensor is operated at a second polling rate faster than the first polling rate and corresponding to a lower potential latency. Subsequent user-related information is received. Where the subsequent user-related information matches a selected target event, feedback associated with the selected target event is provided to the user via the head-mounted display device.

摘要: A camera module is disclosed including an image sensor having an associated optical filter configured to receive a first set of one or more wavelengths of light, and a housing around the image sensor. The housing has an associated optical filter configured to allow a second set of one or more wavelengths of light to pass through the housing and to block the first set of one or more wavelengths of light from passing through the housing. In examples, the second set of one or more wavelengths of light may be light in the visible range of wavelengths, and the housing may be transparent.

摘要: An optical stack includes a first variable element and a second variable element. The first variable element is configured to vary light transmission through the first variable element as a function of a first control signal. The second variable element is in series with the first variable element and is configured to vary light transmission through the second variable element as a function of a second control signal. A controller dynamically supplies the first control signal to the first variable element and supplies the second control signal to the second variable element.

摘要: Methods for generating and displaying images associated with one or more virtual objects within an augmented reality environment at a frame rate that is greater than a rendering frame rate are described. The rendering frame rate may correspond with the minimum time to render images associated with a pose of a head-mounted display device (HMD). In some embodiments, the HMD may determine a predicted pose associated with a future position and orientation of the HMD, generate a pre-rendered image based on the predicted pose, determine an updated pose associated with the HMD subsequent to generating the pre-rendered image, generate an updated image based on the updated pose and the pre-rendered image, and display the updated image on the HMD. The updated image may be generated via a homographic transformation and/or a pixel offset adjustment of the pre-rendered image.
