Abstract:
Representative embodiments disclose mechanisms for calibrating an eye gaze selection system. When the calibration is triggered, a snapshot of an area around the current user's gaze point is taken. The snapshot area is then animated to cause motion of the snapshot area. As the snapshot is animated, the user's gaze will naturally track the thing the user was focusing on. This creates an eye tracking vector with a magnitude and direction. The magnitude and direction of the eye tracking vector can then be used to calculate a correction factor for the current user's gaze point. Calibration can be triggered manually by the user or based on some criteria such as error rates in item selection by the user.
