Patent ID: 8816995

Claim:
A manual control interface for controlling an apparatus, in particular a motor vehicle, including: a movable part configured to be controlled manually to a plurality of indexed selection positions in a selection direction relative to a support, wherein each selection position indicative of a selection of at least one determined function of the apparatus, a photo-detector configured to generate position signals indicative of the position of the movable part; and a movable holographic element coupled to the moveable part such that displacements of the movable holographic element correspond to displacements of the movable part in the selection direction, wherein the moveable holographic element includes a first series of holograms forming coding motifs corresponding to the selection position of the movable part relative to the support, wherein the coding motifs are projected towards the photo detector when they are illuminated by a suitable light beam, wherein the movable holographic element includes a second series of holograms forming figurative motifs configured to represent the functions of the apparatus, wherein the position of the movable holographic element relative to the support determines which figurative motif is illuminated by the suitable light beam, so as to project the figurative motif corresponding to the selected function towards a display zone visible to the user.
