摘要:
In a device or a method for determining the direction of vision of an eye, a starting point or a final point of a light beam reflected by a part of the eye and detected by a detector system, or of a light beam projected by a projection system onto or into the eye two-dimensionally, describes a pattern of a scanning movement in the eye. The inventive method uses a displacement device that guides the center of the pattern of movement into the pupil or macula center of the eye, and a determination device that uses the pattern of movement of the scanning movement to determine the pupil center or macula center.
