摘要： An apparatus for dynamically determining a displacement of a target sensor in an electronic system is disclosed. The apparatus can comprise a non-line-of-sight sensor rigidly mounted on or proximate to the target sensor and configured to measure a parameter that varies with the displacement of the target sensor. The apparatus further can comprise at least one processor coupled to the non-line-of-sight sensor and configured to compute the displacement of the target sensor based on the parameter, and to compute an adjustment value based on the computed displacement.

摘要： An example see-through head-mounted display system includes a freeform prism and a display device configured to emit display light through the freeform prism to an eye of a user. The see-through head-mounted display system may also include an imaging device configured to receive gaze-detection light reflected from the eye and directed through the freeform prism.

摘要： Embodiments are described herein for determining a stabilization plane to reduce errors that occur when a homographic transformation is applied to a scene including 3D geometry and/or multiple non-coplanar planes. Such embodiments can be used, e.g., when displaying an image on a head mounted display (HMD) device, but are not limited thereto. In an embodiment, a rendered image is generated, a gaze location of a user is determined, and a stabilization plane, associated with a homographic transformation, is determined based on the determined gaze location. This can involve determining, based on the user's gaze location, variables of the homographic transformation that define the stabilization plane. The homographic transformation is applied to the rendered image to thereby generate an updated image, and at least a portion of the updated image is then displayed.

摘要： Various embodiments relating to using motion based view matrix tuning to calibrate a head-mounted display device are disclosed. In one embodiment, the holograms are rendered with different view matrices, each view matrix corresponding to a different inter-pupillary distance. Upon selection by the user of the most stable hologram, the head-mounted display device can be calibrated to the inter-pupillary distance corresponding to the selected most stable hologram.

摘要： A technique is described herein for determining a pose of at least one mobile controller. The technique involves using a transmitter to initially emit a magnetic field and/or electromagnetic radiation at an elevated-power level, with respect to a normal-use power level. A receiver detects the magnetic field and/or electromagnetic radiation, to provide received signals. A tracking component determines the pose of the controller based on the received signals. Thereafter, the technique transmits the magnetic field and/or electromagnetic radiation at the normal-use power level. In one implementation, a head-mounted display (HMD) uses the above-summarized technique to find the controller when the user initially dons the HMD. This is useful because the controller may be invisible to the user who dons the HMD because it is out-of-range with respect to the normal-use operating space of the HMD.

摘要： Various embodiments relating to selection of a user interface object displayed on a graphical user interface based on eye gaze are disclosed. In one embodiment, a selection input may be received. A plurality of eye gaze samples at different times within a time window may be evaluated. The time window may be selected based on a time at which the selection input is detected. A user interface object may be selected based on the plurality of eye gaze samples.

摘要： A head-mounted display device is disclosed, which includes an at least partially see-through display, a processor configured to detect a physical feature, generate an alignment hologram based on the physical feature, determine a view of the alignment hologram based on a default view matrix for a first eye of a user of the head-mounted display device, display the view of the alignment hologram to the first eye of the user on the at least partially see-through display, output an instruction to the user to enter an adjustment input to visually align the alignment hologram with the physical feature, determine a calibrated view matrix based on the default view matrix and the adjustment input, and adjust a view matrix setting of the head-mounted display device based on the calibrated view matrix.

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： A mixed-reality system causes a magnetic transmission device to transmit a magnetic field signal. The mixed-reality system also causes a magnetic-field sensing device to determine a measurement of the magnetic field signal. The mixed-reality system then identifies, using one or more input devices, that a magnetically-interfering object is located within a same environment as both the magnetic transmission device and the magnetic-field sensing device. The mixed-reality system also determines one or more characteristics of magnetic field interference that the magnetically-interfering object is imparting on the magnetic transmission device or the magnetic-field sensing device. The mixed-reality system then computes an adjustment to a pose-estimation model based upon the one or more characteristics of magnetic field interference. The pose-estimation model is used to calculate a pose of at least one of the magnetic transmission device or the magnetic-field sensing device.
