    摘要: Systems and methods are described for improving gaze estimation based on glints. An example method may be executable to receive glint-location data indicating a location for each of one or more glints that are reflected from an eye. The glint-location data may be captured by an imaging device that is attached to a head-mountable display (HMD). The method may be further executable to determine a plurality of normalized pupil locations comprising at least a first and a second normalized pupil location. Each normalized pupil location may be determined based on the glint-location data for a different combinatoric subset of the one or more glints. The method may be further executable to determine a regression model to fit the plurality of normalized pupil locations to an expected gaze location, and perform a gaze-tracking process based on the regression model.

    摘要: A wearable computing device or a head-mounted display (HMD) may be configured to track the gaze axis of an eye of the wearer. In particular, the device may be configured to observe movement of a wearer's pupil and, based on the movement, determine inputs to a user interface. For example, using eye gaze detection, the HMD may change a tracking rate of a displayed virtual image based on where the user is looking. Gazing at the center of the HMD field of view may, for instance, allow for fine movements of the virtual display. Gazing near an edge of the HMD field of view may provide coarser movements.

    摘要: Methods and systems involving a navigable area in a head-mounted display (HMD) are disclosed herein. An exemplary system may be configured to: (a) cause a head-mounted display (HMD) to provide: (i) a viewing window that is fully visible in a field of view of the HMD, (ii) a navigable area that is not fully visible in a field of view of the HMD such that the viewing window displays a first portion of the navigable area, and (iii) a media object that is associated with a viewing-window state; (b) receive first head-movement data that is indicative of head movement from a first position of the HMD to a second position of the HMD; and (c) based on (i) the first head-movement data and (ii) the viewing-window state, cause the viewing window to display a second portion of the navigable area which includes the media object.

    摘要: A head-mounted display (HMD) may include an eye-tracking system, an HMD-tracking system and a display configured to display virtual images. The virtual images may present an augmented reality to a wearer of the HMD and the virtual images may adjust dynamically based on HMD-tracking data. However, position and orientation sensor errors may introduce drift into the displayed virtual images. By incorporating eye-tracking data, the drift of virtual images may be reduced. In one embodiment, the eye-tracking data could be used to determine a gaze axis and a target object in the displayed virtual images. The HMD may then move the target object towards a central axis. The HMD may also record data based on the gaze axis, central axis and target object to determine a user interface preference. The user interface preference could be used to adjust similar interactions with the HMD.
