Abstract:
An operating device comprising: an actuator (1) movable around a pivot point with at least two adjustment degrees of freedom, an evaluation device (3, 5, 6, 9, 11) for evaluating a position of the actuator (1) optically, an apparatus for changing a light beam optically, and an optical sensor;wherein the evaluation device comprises the apparatus for changing the light beam, and the evaluation device evaluates a multiplicity of positions; wherein the actuator (1) operates the apparatus (3, 11) for changing the light beam (LS, LSP) optically, the optical change in the light beam (LR, LRP) is detected by the optical sensor (6, 9); and the apparatus (3, 11) for changing the light beam optically is constructed as a variously colored single disk (11) or a variously colored section of a single sphere (3), said colored disk and said colored spherical section each having the multiplicity of positions which are variously colored.
