SCENE ANALYSIS FOR IMPROVED EYE TRACKING

摘要

Technologies related to scene analysis for improved eye tracking are generally described. In some examples, detected gaze targets may be derived from gaze direction information from an eye-facing sensor. Detected gaze target positions and/or motion may be improved by capturing and analyzing digital scene information from a scene visible by the eye. Digital scene information captured by a digital camera may be analyzed to identify potential gaze targets, such as stationary gaze targets, moving gaze targets, and/or accelerating gaze targets. Detected gaze targets may be modified to positions of selected gaze targets.

主权项

1. An eye tracking method comprising:
receiving, by a computing device, gaze direction information for at least one eye from an eye-facing sensor; receiving, by the computing device, digital scene information from a digital camera, wherein the digital camera is oriented to capture the digital scene information from a scene visible by the at least one eye; determining, by the computing device, based on the gaze direction information, a detected gaze target within the digital scene information; analyzing, by the computing device, the digital scene information to identify one or more potential gaze targets within the digital scene information, wherein the one or more potential gaze targets comprise one or more of:
a stationary gaze target within the digital scene information;a moving gaze target within the digital scene information; oran accelerating gaze target within the digital scene information; selecting, by the computing device, a selected gaze target among the one or more identified potential gaze targets; and modifying, by the computing device, the detected gaze target to comprise a position of the selected gaze target.
