Abstract: [PROBLEM TO BE SOLVED] To provide a newly function measurement apparatus capable of measuring a function of a person while a test subject moves a whole body thereof. [SOLUTION] A mat unit 7 includes foot switches SW1 to SW4, and detects step motion of a test subject. The test subject performs the step motion on the foot switches SW2 and SW3 while sitting. ON/OFF information of the foot switches SW1 to SW4 is transmitted to an adapter 1 by infrared communication. A cartridge 3 is inserted into the adapter 1. The ON/OFF information of the foot switches SW1 to SW4 is sent to the cartridge 3 via the adapter 1. A processor 20 incorporated in the cartridge 3 measures a time from when any one of the foot switches SW2 and SW3 detects the step motion to when the predetermined number of times of the step motion is detected. The measuring result is displayed on a television monitor 5.

Abstract: A manipulation object 400 displayed on a television monitor 5 performs the same various motions as various motions which a player performs on a mat 2 (a motionless state, a walking motion, a running motion, a side stepping motion, a jumping motion and a squatting motion). Accordingly, the player can have an experience as if he were actually moving in a virtual space through the manipulation object 400 by performing these motions on the mat 2.
