An eye tracker is a computer peripheral that uses a camera to follow users eyeballs to predict where they are looking on a computer screen. That information can be used as a substitute for a cursor, or to show other users where you are focused.

Eye trackers can be small webcams placed on your desk or clipped to your monitor. They are also sold as wearable devices, which are worn like glasses.
