1. A device for determining at least one of a position and an orientation of an eye, comprising:
- a projection system for projecting infrared light onto or into the eye having a projection light guiding arrangement that deflects the projected light onto a specific part of the eye,a detector system for detecting said light after it has been reflected by a part of the eye,a determination device that determines a position of at least one characteristic of the eye from the detected light, andan orientation determining device for determining the position or orientation of the device relative to the environment,wherein the device is wearable.

Abstract
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.
