Abstract: 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.

Abstract: 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.

Abstract: Methods and systems for unlocking a screen using eye tracking information are described. A computing system may include a display screen. The computing system may be in a locked mode of operation after a period of inactivity by a user. Locked mode of operation may include a locked screen and reduced functionality of the computing system. The user may attempt to unlock the screen. The computing system may generate a display of a moving object on the display screen of the computing system. An eye tracking system may be coupled to the computing system. The eye tracking system may track eye movement of the user. The computing system may determine that a path associated with the eye movement of the user substantially matches a path associated with the moving object on the display and switch to be in an unlocked mode of operation including unlocking the screen.

Abstract: This disclosure relates to proximity sensing for wink detection. An illustrative method includes receiving data from a receiver portion of a proximity sensor. The receiver portion is disposed at a side section of a head-mountable device (HMD). When a wearer wears the HMD, the receiver portion is arranged to receive light reflected from an eye area of the wearer, the proximity sensor detects a movement of the eye area, and the data represents the movement. The method includes determining that the data corresponds to a wink gesture. The method also includes selecting a computing action to perform, based on the wink gesture. The method further includes performing the computing action.

Abstract: Exemplary methods and systems help provide for tracking an eye. An exemplary method may involve: causing the projection of a pattern onto an eye, wherein the pattern comprises at least one line, and receiving data regarding deformation of the at least one line of the pattern. The method further includes correlating the data to iris, sclera, and pupil orientation to determine a position of the eye, and causing an item on a display to move in correlation with the eye position.

Abstract: 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.

Abstract: An optical system has an aperture through which virtual and real-world images are viewable along a viewing axis. The optical system may be incorporated into a head-mounted display (HMD). By modulating the length of the optical path along an optical axis within the optical system, the virtual image may appear to be at different distances away from the HMD wearer. The wearable computer of the HMD may be used to control the length of the optical path. The length of the optical path may be modulated using, for example, a piezoelectric actuator or stepper motor. By determining the distance to an object with respect to the HMD using a range-finder or autofocus camera, the virtual images may be controlled to appear at various distances and locations in relation to the target object and/or HMD wearer.

Abstract: A “construction set” consisting of active and passive parts connected by joints that can be manipulated to form an movable articulated assembly representing things like animals and skeletons. Each active part includes a position sensor for acquiring and storing position data specifying a sequence of positions assumed by the active part as the assembly is reshaped, and a controllable drive motor for moving the active part relative to a connected part in accordance with the position data.

Abstract: An array of piezoelectric ceramic sensors affixed to a flexible plastic membrane forms a target surface and the signals produced by the sensors are processed to produce an output signal which indicates the location where a liquid stream strikes the target. The sensor array is used to detect the presence and location of a liquid stream from a pressurized nozzle used to play an interactive game. The stream presence and position signals are fed in real time to a (personal) computer which produces an output display indicating where the target was struck by the stream. The stream detection array may be used in a variety of applications.
