    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： Example methods and systems determine a position of a portion of a human eye based on electromagnetic radiation reflected from the surface of the human eye. A sensor associated with a computing device can be calibrated in response to an event. The computing device can receive data indicative of electromagnetic radiation reflected from a human eye. The computing device can determine a position of a portion of the human eye based on the received data indicative of electromagnetic radiation. The computing device can generate an indication including the position of the portion of the human eye. The computing device can transmit the indication from the computing device. In some embodiments, the data indicative of electromagnetic information can be provided by electromagnetic emitter/sensors mounted on a wearable computing device directed toward a human eye of a wearer of the wearable computing device.

    摘要： Methods and systems for intelligently zooming to and capturing a first image of a feature of interest are provided. The feature of interest may be determined based on a first interest criteria. The captured image may be provided to a user, who may indicate a level of interest in the feature of interest. The level of interest may be based upon to store the captured image and capture another image. The level of interest may be a gradient value, or a binary value. The level of interest may be based upon to determine whether to store the captured image, and if so, a resolution at which the captured image is to be stored. The level of interest may also be based upon to determine whether to zoom to and capture a second image of a second feature of interest based on the first interest criteria or a second interest criteria.

    摘要： A wearable computing device is authenticated using bone conduction. When a user wears the device, a bone conduction speaker and a bone conduction microphone on the device contact the user's head at positions proximate the user's skull. A calibration process is performed by transmitting a signal from the speaker through the skull and receiving a calibration signal at the microphone. An authentication process is subsequently performed by transmitting another signal from the speaker through the skull and an authentication signal is received at the microphone. In the event that frequency response characteristics of the authentication signal match the frequency response characteristics of the calibration signal, the user is authenticated and the device is enabled for user interaction without requiring the user to input any additional data.
