Patent ID: 8382285

Claim:
A device for determining the position and/or the orientation of an eye, comprising: a detector system for detecting light reflected by at least a part of the eye, wherein the position of the pupillary center of the eye is determined from the detected light and is used for determining the position and/or orientation of the eye relative to the device, a camera for capturing a first camera image and at least a second camera image by photographing the environment at a time interval from one another, wherein said camera is rigidly connected with the device, wherein the first camera image and the at least second camera image are compared with one another in a common coordinate system for determining the position and/or orientation of the device relative to the environment; and a projection system for projecting perceivable information into the eye such that it is correlated with the determined position and/or orientation of the eye and the determined position and/or orientation of the device, wherein the device is integrated into a portable object which is movable relative to the environment and relative to a carrier of the device.
