Device and method for determining the viewing direction in terms of a fix reference co-ordinates system

摘要

A device for determining the viewing direction relative to a fixed reference co-ordinate system comprises a detector for detecting electrooculograms so as to detect the viewing direction of the eyes of a user relative to the user's head. Furthermore, an inertial navigation system is provided for detecting the position of the head relative to said fixed reference co-ordinate system. Finally, the device comprises a computation unit for determining the viewing direction of the eyes of the user relative to said fixed reference co-ordinate system from the detected viewing direction of the eyes relative to the head and from the detected position of the head relative to said fixed reference co-ordinate system.
