Answer: (b).For controlling a computer by looking at it. Explanation:Eyegaze systems are designed to allow users to control a computer simply by looking at it. These systems use a low-power laser that is reflected off the retina of the eye. By tracking the reflected beam, the system can determine the direction in which the eye is looking, thereby controlling the movement of the screen cursor or other computer functions.
