摘要： 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.

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.

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.
摘要翻译：可戴式计算装置或头戴式显示器（HMD）可以被配置为跟踪佩戴者眼睛的视线轴线。特别地，该装置可以被配置为观察佩戴者的瞳孔的移动，并且基于移动来确定对用户界面的输入。例如，使用眼睛注视检测，HMD可以基于用户正在看的位置来改变所显示的虚拟图像的跟踪率。例如，注视HMD视野的中心可以允许虚拟显示器的精细移动。在HMD视野边缘附近凝视可能会提供较粗糙的动作。

摘要： 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.

摘要： 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.
