The system has a compact, portable input device (1) which transmits a laser beam. An image acquisition system (2), with an objective (2.1), is used to monitor a limited area including the laser beam impact spot when the input device is directed toward the area. A picture analyser determine the presence and position of the spot in the area, and relates those informations with corresponding time data. An output device (4), which can be a micro-controller, associates the obtained temporal informations to corresponding command signal. An operator interface (5) is provided to input data required for associating obtained information to desired command signals. This can take the form of a task look-up table used to select the function or mode to be actioned and to pass electronic signals to the appts. to be controlled. The interface includes a keyboard, a screen, and a memory.
