ABSTRACT:
In an electrooptical arrangement for remotely controlling an electronic apparatus with a remote control transmitter, the transmitter is formed with three sources of radiation whose radiation patterns are different from each other and can be comparatively detected relative to each other to indicate the tilting of the transmitter in different reference plane directions. A radiation detector at the receiver side detects the different radiation intensities for the signals from the three sources, and the relation between the signal intensities is evaluated to determine the tilt angles of the remote control transmitter in the reference plane directions.
