  • Automatic calibration of a gaze direction algorithm from user behavior
    Patent number: 8982046
    Abstract: A method of calibrating the eye gaze direction of a user, the method including the steps of: (a) monitoring a user's eye gaze direction whilst carrying out a series of predetermined tasks, each of the tasks having an expected subject gaze direction; and (b) correlating the user's eye gaze direction with the expected direction for a statistically significant period of time; (c) calculating, from the correlating step, a series of likely eye gaze direction usage parameters associated with the user.
    Type: Grant
