    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: An augmented reality device including a plurality of sensors configured to output pose information indicating a pose of the augmented reality device. The augmented reality device further includes a band-agnostic filter and a band-specific filter. The band-specific filter includes an error correction algorithm configured to receive pose information as filtered by the band-agnostic filter and reduce a tracking error of the pose information in a selected frequency band. The augmented reality device further includes a display engine configured to position a virtual object on a see-through display as a function of the pose information as filtered by the band-agnostic filter and the band-specific filter.

    摘要: Embodiments that relate to communicating to a user of a head-mounted display device an estimated quality level of a world-lock display mode are disclosed. For example, in one disclosed embodiment a sensor data is received from one or more sensors of the device. Using the sensor data, an estimated pose of the device is determined. Using the estimated pose, one or more virtual objects are displayed via the device in either the world-lock display mode or in a body-lock display mode. One or more of input uncertainty values of the sensor data and pose uncertainty values of the estimated pose are determined. The input uncertainty values and/or pose uncertainty values are mapped to the estimated quality level of the world-lock display mode. Feedback of the estimated quality level is communicated to a user via device.
