Abstract
The invention relates to a device for determining a fixation point (3) on screen (1), comprising an eye reference point detector (6) an a direction of view detector (9) which is mounted on a pivoting/inclining element (11) in such a way that it can be pivoted and inclined. By means of three transformation steps, namely rotation, scaling and translation, a direction of view function can be transformed by a system of direction of view coordinates assigned to the direction of view detector (9) in an object coordinate system which is assigned to the screen (1). In this way it is possible, to trigger certain functions by fixation of areas of the screen (1) rendered sensitive, whereby the eye plays the role of a mouse.
