For example, with respect to respective players, five kinds of bio-information, e.g., pulse, No. of breaths, body temperature, sweating and wink are respectively measured to calculate, as data of coordinate

**1**, linear sum of pulse, body temperature and sweating among the measured respective data, and to calculate, as data of coordinate

**2**, linear sum of the No. of breaths and wink. For example, since pulse, body temperature and sweating are increased when excited, the coordinate

**1** can be regarded as coordinate representing “degree of enthusiasm”. Moreover, since the number of breaths and wink are not so changed if player is cool, the coordinate

**2** can be regarded as coordinate representing “degree of coolness”.
