INPUT DEVICE AND COMMUNICATION SYSTEM

PROBLEM TO BE SOLVED: To provide an input device and a communication system for making it unnecessary for a user to mount any special sensing equipment on a human body, and for making it possible for the user to easily operate external equipment. SOLUTION: Four air bag units A1 to A4 respectively equipped with air pressure sensors for measuring an internal air pressure are overlapped and lattice arrayed like the shape of parallel cross, and a position estimation circuit 100 decides the position of the head to be placed according to the combination of the detection results of each air pressure sensor. Then, the position estimation circuit 100 is made to function as a remote controller by outputting a command corresponding to the position of the head through an output interface 200 to external equipment.
