BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the biofeedback game machine according to the present invention shown in FIG. 1, reference numeral 1 denotes a holder (not shown) which is attached to, for example, an earlobe, and outputs a biological signal (pulse,
Heart rate, etc.), 2 is a CPU of a computing device,
3 is a storage device for storing games, 4 is a display, 5
Is a controller, 6 is a sensor checking means, 9 is a start switch, 10 is a RAM of a work memory, 11 is a timer, and 18 is a speaker.

[0007] When the earlobe is sandwiched by the holder and attached to the ear,
Light emitted from a light-emitting body built in the sensor 1 (not shown) attached to the holder is incident on the ear, and the light amount of the blood flow, which is changed by the heartbeat, is detected by the light receiving element of the sensor 1. is there. The storage device 3 for storing the game program is composed of a cassette or disk, and is a program ROM. The CPU 2 reads the program and displays the game screen on a CRT or the like of the display 4.

The controller 5 has a start switch 9 and other various operation keys necessary for playing. A start signal by operating the start switch 9 is sent to the timer 11. In such a configuration, the CPU 2 changes the game content displayed on the display 4 based on a command from the controller 5, and further slightly corrects the game content based on the detection result by the sensor 1, for example. The biological signal can be reflected in the game.

The sensor check means 6, which is a feature of the present invention, sends a start signal to the CPU 2 to make the start signal (the signal from the start switch 9) significant. CPU
2 can be started by the output of the start switch 9, and thereafter the CPU 2 can continuously start the operation by the output of the start switch 9. In this example, the timer 11 is activated by the start signal a and outputs one timer signal b at intervals of 3 seconds.

The operation of the biofeedback game machine of the present invention will be described with reference to the timing chart of FIG.
Before the start of the game, the player attaches the sensor 1 to the ear by pinching the earlobe with the holder. The sensor 1 detects a detection signal indicating a heartbeat of a biological signal and sends the detection signal to the CPU 2 at all times. The player holds the controller 5 in his hand, and the time t1
When the start switch 9 is pressed, a start signal a is sent to the timer 11.

The sensor check means 6 observes the detection signal c from the sensor 1 from the first time pulse b coming from the timer 11 at time t1 until the arrival of the time pulse b, for example, three seconds later (until time t2). In this example, the detection signals c observed during the three seconds (from time t1 to time t2) are sequentially sent to the sensor check means 6, and in FIG. A prescribed number (three in this example) of detection signals c are input. For this reason, the sensor checking means 6 which has received the specified number of detection signals c set in advance sends a start signal d indicating that the start is significant to the CPU 2 after the time t2 has elapsed.

Based on the signal d, the CPU 2 determines that the sensor 1 is in a state of normally detecting a biological signal, and starts the game by starting the game. If the sensor 1 is set normally, the sensor check means 6 outputs the signal d of FIG. 2, and the CPU 2 always starts the game progress by this output signal. Even if the game is in progress, if this signal d is not output, the game by the CPU 2 does not proceed.

The CPU 2 reads a program from the storage device 3, displays a game screen on the display 4, and the player advances the game by operating keys of the controller 5. The biological signal c from the sensor 1 as the game progresses
Is always sent to the sensor checking means 6 to check whether a specified number (three in the present application) of the detection signals c are obtained in three seconds, and the mounting state of the sensor 1 is constantly monitored. At the start of the game and during the progress of the game, if three detection signals c are not obtained in three seconds, the following attention is urged to the player.

That is, if the sensor 1 comes off or comes off the earlobe, there is no detection signal c corresponding to the pulse rate, or even if it does not reach the specified number of three, the sensor check means 6 The speaker 18 sounds a warning of "Let's lose" or displays a warning screen such as "Please check the sensor" on the display 4 to alert the player. Even if a certain period of time has elapsed after this warning display, within a predetermined period of time (from time t1 to time t2
If the specified number (three in the present application) of the detection signals c is not input during the period, the CPU 2 stops the progress of the game.

Embodiment 2 In the present embodiment, whether or not the game can be started or progressed is determined based on whether or not the pulse rate level has reached a certain level. That is, as shown in FIG. 3, in the present embodiment, a calculation unit 7 and a level value memory 8 are provided. The detection signal c is input from the sensor 1 to the calculation unit 7, and the calculation unit 7 constantly measures the period of the instantaneous heartbeat of the player from the detection signal c. I'm looking for a pulse rate.

The sensor check means 6 inputs the one-minute pulse rate from the calculation unit 7 during a period from time t1 to time t2 (see FIG. 2), and outputs a start signal (signal from the start switch 9) to the CPU 2 significantly. Is sent. The level value memory 8 is composed of a ROM, and stores in advance the average pulse rate per minute of a human. The average one-minute pulse rate is sent to the sensor check means 6 as a reference level value, and is compared with the one-minute pulse rate from the calculation unit 7.

The calculation unit 7 synchronizes the first time coming from the timer 11 and the pulse b of the timer signal with the detection signal c from the sensor 1 for a time t2, for example, three seconds after the time t1.
Observe up to. The detection signal c from the sensor 1 is input to the calculation unit 7, and the calculation unit 7 calculates a time interval between the detection signals c that are sequentially observed. That is, the pulse rate for one minute is obtained for each beat from the reciprocal of the heartbeat interval at the moment of the player. This pulse rate is sent to the sensor check means 6, where the average 1 of the human read from the level value memory 8 is read.
The pulse rate per minute is compared with, for example, 58 to 63 times.

If the pulse rate is within the range of 58 to 63 times, the sensor check means 6 sends an activation signal d which activates the progress of the game by the CPU 2 and makes the progress significant.
U2 determines that the sensor 3 is in a state of normally detecting a biological signal, and starts the game. The subsequent operation is almost the same as in the first embodiment.

The reference for starting the game is not limited to the case where the pulse signal is continuously detected for 3 seconds, but may be continuously detected for 3 seconds or more for further improving the accuracy. Further, the absolute value of 58 to 63 times of the pulse rate is not definitive in the present invention, and can be set before, after or other than 60 times. Since the gamer's pulse rate and the like are accurately fed back to the game, the player can be absorbed in the game. As the start switch 9, a power switch or a selection switch of a game menu may be used.
