PROBLEM TO BE SOLVED: To perform conversion to data with which the movement of a large part, etc., of the body can be recognized by tranducing the operation of a riser member connected to a support member on which a person can sit into an electric signal and transmitting it to a computer system. SOLUTION: The input device 18 consists of the riser member 200 including a right-left symmetrical main body 202 and a cross member 208 having a couple of handle members 210 and 212 at both ends and a rigid support member 206 which has a top surface 216 where a person can sits, and the riser member 200 is sized corresponding to the sitting height of an infant. The right-left symmetrical main body 202 of the riser member 202 is in tubular structure and an elastic device 218 stored in a hollow internal space 203 holds the riser member 200 at a specific position on the rigid support member 206 when the riser member 200 is applied with no external force. A transducing device consisting of plural position sensors, direction determining circuits, and interface circuits senses the operation of the riser member 200 and transmits it to the computer in the form of the electronic signal. |
