ABSTRACT:
The system comprises a plurality of objects such as lamps (11-15), venetian blinds (16, 17) and air-conditioning appliances (18) and a hand-held infrared remote control unit (40) for transmitting control signals. A separate receiver (21-28) is allocated to each one of the objects (11-18) and the transmitter of the remote control unit (40) transmits the control signals in a relatively narrow transmission beam (42). An object is selected by directing the portable transmitter (40) towards this object. Consequently, the user does not need to give a further indication of the object and the system can be operated in a simple manner. Less frequent communication with the system is possible via a separate interface unit (70). Specific objects can only be operated by certain users by transmitting an identification code along with the control signal. The identification code can also be used for the purpose of localization and for access control.
