Abstract: A terminal with a line-of-sight tracking function is disclosed. The terminal with a line-of-sight tracking function includes a body, a camera, and at least two light emitting diodes. The camera and the at least two light emitting diodes are mounted on the body, so that the terminal can emit a ray by using the at least two light emitting diodes, to ensure that the emitted ray can be shined on an eye of the user when the user is at different angles. After the ray is reflected by the eye of the user, the terminal can collect the reflected ray by using the camera, obtain an eye image of the user, and track a line of sight of the user based on the eye image, thereby increasing a success rate of line-of-sight tracking.
