PROBLEM TO BE SOLVED: To control a game based on the result of judgement about the change of a player's mind and body condition by making the judgement on the condition, using the minute-conversion number of bio-signals computed on the basis of intervals between bio-signals before and after measurements, or the signal intervals themselves as data. SOLUTION: CPU 9 receives heartbeat data and measures intervals between the heartbeats, as soon as a player starts a game with heartbeat detectors 1 and 1a attached to his/her fingers. At the same time, the CPU finds minute-conversion heartbeat number data and writes the data on the areas 8a and 8b of RAM 8. Then, the heartbeat number data of each player is outputted to CRT 6, and plotted on a graph shown on display columns 3 and 3a. In this case, the data graph is shown, with the values of the previous heartbeat number data taken as an X-axis, and the values of the immediately following heartbeat number data as a Y-axis. Then, the player's mind and body condition are judged to control a game, by use of the length of a straight line from a linear function of Y=X, and the length of a straight line from a linear function of Y=-X respectively as parameters.
