Abstract:
1. One or more computer storage media devices storing computer-executable instructions for performing a method for estimating user eye gaze, the method comprising: determining at least one gaze target area by: acquiring a plurality of images of a user's eye captured via at least one first image sensor on a head-mounted device, acquiring at least one image of at least part of the user's field of view captured via at least one second image sensor on the head-mounted device, determining the at least one gaze target area within the at least one image of the at least part of the user's field of view based on analysis of at least one of the plurality of images of the user's eye; and estimating an enhanced user eye gaze using the at least one gaze target area by: identifying, using a database that maps eye information to known gaze lines, a narrowed subset of the known gaze lines that intersect the at least one gaze target area, identifying, from the database, a narrowed subset of the eye information that corresponds with the narrowed subset of the known gaze lines, comparing user eye information derived from at least one the plurality of images of the user's eye to the narrowed subset of the eye information, identifying first eye information in the narrowed subset of the eye information as matching at least a portion of the user eye information derived from at least one of the plurality of images of the user's eye, and identifying a first known gaze line corresponding with the first eye information in the narrowed subset of the eye information as an enhanced estimated user eye gaze.
