Abstract
The invention concerns a device for displaying a virtual image, particularly of the control panel of an elevator cabin. The device includes a projector for projecting at least the virtual image of an elevator control panel from or near the cabin ceiling (13) onto a wall surface (9) of the cabin, in an appropriate position so that the virtual control elements (27) of the panel are recognized as such by the operator and by a control sensor for activating the control of the elevator in the classic manner.
