    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： 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.

    摘要： Examples methods and systems for distinguishing winks from other eye motions are described. In some examples, a method for distinguishing winks from other eye motions may account for changes in orientation of a computing device relative to a user, calibrate eye gesture recognition, or increase efficiency of the computing device. A computing device may be configured to receive sensor data corresponding to an eye and determine a distribution of magnitude changes in the sensor data over an interval of time. The computing device may identify clusters that correspond to ranges of magnitude changes within the distribution and use the clusters as reference data to identify ranges of sensor data for different types of eye motions, including differentiating winks from clusters indicative of ranges of normal eye activity and blinks.
