Abstract
A control device includes a mobile control member (F) for emitting a diffuse light beam (LS). An electronic processing unit (V) generates a graphic user interface (VA) and is advantageously connected, via a data link (K1, K2), to a display unit (D, VD). The display unit (D, VD) displays the graphic user interfaces (VA). An optical receiver sensor (S) converts movement directions (B) of the diffuse light beam (LS) of the mobile control member (F) into a control signal. In the processing unit (V), the control signal effects, in accordance with the movements of the diffuse light beam (LS), tracking of a graphic control marker (C) and/or of the position of the graphic user interface (VA) and/or of parts of the interface (VA) and/or of visual elements (C) in the interface (VA).
