A method for inputting commands to a holographic input system, includes the steps of generating a virtual image of an input device by illuminating a hologram of the input device by means of a corresponding reference beam, the hologram being prerecorded on a holographic support; optically detecting a position of at least one actuator for operating the input device with respect to the virtual image of the input device; and issuing at least one command signal corresponding to the position of that at least one actuator as optically detected. The optical detection operation further includes providing at least one actuation hologram corresponding to the at least one actuator being placed at a specified position with respect to the virtual image of the input device, illuminating the at least one actuator with a beam, in order to obtain scattering into a corresponding object beam interacting with one actuation hologram through the corresponding object beam; generating a respective actuation detection beam through the interaction; and detecting the respective actuation detection beam to issue the command signal.
