In some examples, the location may be identified based upon an eye image of one or more eyes of the user. The eye image may be separate from the image described above. In such examples, the eye image may be analyzed to identify where the user is looking. For example, each set of one or more pixels of the eye image may be determined to correspond to a different set of one or more pixels of the image. In such an example, if the one or more eyes in the eye image are determined to be looking at a particular set of one or more pixels of the eye image, the location in the image may be identified as a set of one or more pixels of the image that correspond to the particular set of one or more pixels of the eye image. It should be recognized that more than one eye image may be used. For example, an eye image of a first eye and an eye image of a second eye may be used. In some examples, the location may correspond to a location of an object identified in the image. It should also be recognized that other methods for identifying where a user is looking based upon an eye image of one or more eyes of the user may be used.
In other examples, the location may be identified based upon a direction of a gaze of the user. In such examples, instead of using an eye image of one or more eyes of the user, an orientation of a device worn by the user may be used. In one illustrative example, the orientation may include one or more from the set of pitch, yaw, and roll. In such an example, a sensor (e.g., gyroscope) that measures the orientation of the device may be included with the device. It should be recognized that other methods for identifying where a user is looking based upon an orientation of a device may be used.
