An electronic appliance remote controller which includes a display screen (which may be part of the appliance, e.g. a TV screen) for displaying icons representing possible operations of the electronic appliance, and a motion detector circuit for detecting a motion within a field of view of the motion detector circuit. The motion detector circuit detects a predetermined motion of a moving object within the field of view as an indication that a remote control operation is to be started and, thereafter, tracks the movement of the object. The motion detector circuit outputs a cursor control signal representative of the motion of the object. A control circuit, connected to the display screen, the electronic appliance, and the motion detector circuit and supplied with the cursor control signal, controls the display screen to display a movable visual indicator, e.g. a cursor, whose own motion tracks the movement of the moving object and the electronic appliance to perform operations corresponding to the icons selected by the user using the visual indicator.
