Abstract:
A method for determining eye openness with an eye tracking device is disclosed. The method may include determining, for pixels of an image sensor of an eye tracking device, during a first time period when an eye of a user is open, a first sum of intensity of the pixels. The method may also include determining, during a second time period when the eye of the user is closed, a second sum of intensity of the pixels. The method may further include determining, during a third time period, a third sum of intensity of the pixels. The method may additionally include determining that upon the third sum exceeding a fourth sum of the first sum plus a threshold amount, that the eye of the user is closed, the threshold amount is equal to a product of a threshold fraction and a difference between the first sum and the second sum.

Claim (Index 11):
A method for determining eye openness with an eye tracking device, wherein the method comprises:\n receiving, at one or more processors, an image of an eye of a user from an image sensor of an eye tracking device; determining, with the one or more processors, based on the image of the eye, a radius of the pupil; determining, with the one or more processors, based on the radius of the pupil, a total area of the pupil; determining, with the one or more processors, based on the image of the eye and the radius of the pupil, an amount of the total area of the pupil which is not obscured by either eyelid; and determining, with the one or more processors, based on the amount of the total area of the pupil which is not obscured by the eyelid and the total area of the pupil, whether the eye of the user is closed.
