Malte Weiß, 26.08.2002: Fields are loaded by events.
            28.08.2002: Rotation implemented besides rotation outside the sphere.
                        Tests of offset rotation.
            29.08.2002: Sensor fully functional:
                        - Rotation problem solved.
                        - Added rotation functionality for dragging outside the sphere.
