PURPOSE: To control contents in an objective area and to simplify and facilitate operations with the pressing operation of one sensor by providing a pressure sensitive sensor having plural standard detection levels.

CONSTITUTION: Either the scroll of a menu or the fixing of the menu is designated corresponding to the strength of force to push a pressure sensitive sensor 2 of a controller 1. This signal is modulated by a modulation circuit 6 and radiated through an LED 4 as infrared rays, and the menu is displayed at a menu display part 3. When the infrared rays are received by an equipment to be controlled, the menu is displayed at a receiver When the modulated signal is detected, the menu is fixed and corresponding to it, processings are performed. Thus, the scroll of the menu or the fixing of control contents can be performed corresponding to the force impressed to the sensor 2, the control operation can be simplified and facilitated, and the device can be operated even by the physically handicapped as well.
