【0002】 [0002]

【従来の技術】さて、通常のゲームでは、ディスプレイの画面を見ながらゲーム者がキーボード等を操作し、ゲームを進行させる。 BACKGROUND OF THE INVENTION Now, in a normal game, while watching the screen of the display game's operates the keyboard or the like, the progress of the game. ゲームの展開中に、ゲーム者は上手に操作したとか、失敗したとかで興奮する。 Game during the development of the game have Toka was operated skillfully, excited at Toka failed. そして、次は上手に操作しよう、似た場面では一気に勝負しようと意気込むのが通例である。 Then, the next step is trying to skillfully operation, the be enthusiastic about trying to stretch game is in a similar scene is customary. このようなプレーヤから種々の生理的信号、心拍数、脈拍、脳波、顔面温度、皮膚抵抗等を取り込み、これを媒介変数としてゲームの進行や展開に変化を与えるようにしたゲーム機が開発されている。 Various physiological signals from such player, heart rate, pulse rate, brain wave, facial temperature, takes in the skin resistance and the like, which a game machine to give a change in the game progress and development of the parametric is developed there.

【0003】最近のコンピュータを使用するゲーム機では、プレーヤの生理的信号を、ゲームの進行にフィードバックさせて、ゲームを進行させている。 [0003] In the game machine using the modern computer, a physiological signal of the player, and is fed back to the progress of the game, thereby advancing the game. この時の生理的信号には簡便さのために、脈拍数の変化が採用されている。 For convenience the physiological signal at this time, changes in the pulse rate is employed. これは電源により発光された発光体からの光を、 The light from the light emitting element which emitted by the power supply,
人体に入射し、血液の流れにより変化された光量を受光素子で検出するものである。 It enters the human body, and detects the amount of light changed by the blood flow in the light-receiving element. これはプレーヤの瞬間の心拍の周期を常時測定し、その心拍数の逆数から一拍毎に分間の脈拍数を求めている。 It measures the period of the instantaneous heart rate of the player always seeking the pulse rate of one heartbeat every two minutes from the reciprocal of the heart rate. 脈拍数を算出する脈波信号は、耳たぶセンサーから取り入れ、ゲームの進行や演出を変化させている。 Pulse wave signal for calculating the pulse rate, taken from the earlobe sensor, and to change the progress and performance of the game.

【0004】図5において分間の脈拍数の求め方を説明する。 [0004] illustrating the pulse rate of obtaining the minute in FIG. 心拍パルスがp1、p2、p3、p4が時間t Heart rate pulses p1, p2, p3, p4 time t
1、t2、t3、t4、t5に検出された時は、心拍間隔dt1=t2−t1、心拍間隔dt2=t3−t2、 1, t2, t3, t4, when detected in t5, the heartbeat interval dt1 = t2-t1, cardiac interval dt2 = t3-t2,
心拍間隔dt3=t4−t3、心拍間隔dt4=t5− Heart rate interval dt3 = t4-t3, heart rate interval dt4 = t5-
t4、心拍間隔dt5=t6−t5等が分単位で計測される。 t4, like cardiac interval dt5 = t6-t5 is measured in minutes. 脈拍数が1分間の心拍数であるので、心拍間隔d Since pulse rate is beats per minute, heart rate interval d
t1=t2−t1の逆数が例えば、心拍間隔dt1=t t1 = t2-t1 reciprocal of example, heart rate interval dt1 = t
2−t1=0.0143分なら、この間の心拍数は1/ If the 2-t1 = 0.0143 minutes, during this time of the heart rate 1 /
0.0143=約70となる。 0.0143 = about 70.

【0006】受光素子は発光体からの光だけではなく、 [0006] The light-receiving element is not only the light from the light emitting body,
外部の光、外乱光にも反応する場合があり、前述のノイズn1、n2が混入する場合に相当する。 External light, may also react to the disturbance light, it corresponds to the case where the noise n1, n2 mentioned above is mixed. 従って心拍数の測定値には誤差の原因になっていた。 Therefore, the measurement of the heart rate had caused the error. 一般に、ゲームの進展につれてディスプレーの画面が次々に変化することになり、画面の明暗の切り替えが不規則に行われている。 Generally, the screen of the display as the progress of the game is to change one after another, the switching of the brightness of the screen have been made irregularly. この画面の切り替えに基づく光量変化がセンサーの受光素子に感知されてしまい、これがノイズとして入り込み、その間の瞬時脈拍数の誤差の原因になっていた。 The light amount change based on the switching of the screen will be perceived in the light receiving element of the sensor, which enters as noise, it was causing therebetween instantaneous pulse rate errors.

【0007】 [0007]

【発明が解決しようとする課題】上述の如く、テレビゲーム機においては、ゲームの進展につれてディスプレイの画面の明暗の切り替えが頻繁に行われているので、この画面の明暗の変化やあるいは室内灯のオン/オフ等による外部の光が脈拍センサの受光素子にノイズとして入ることが多かった。 As THE INVENTION Problems to be Solved] described above, in the video game machine, since the switching of the brightness of the display screen as the progress of the game is frequently performed, changes and or interior light brightness of the screen external light by oN / oFF and the like were often enters as noise to the light receiving element of pulse sensor. また、プレーヤがプレー中に無意識に耳たぶセンサーや脈拍センサに触れたり、身体から外したり、動かしても、更には室内灯のオン/オフによっても外部の光が入り込んでしまうので、ノイズとして捉えられその瞬間の脈拍数を誤って計測してしまう。 Further, the player may touch earlobe sensor or pulse sensor unintentionally during play, or removed from the body, it is moved, since more may enter the external light by the on / off interior lights, taken as noise resulting in a measurement by mistake the pulse rate of the moment. このような原因で、バイオフィードバック付きのゲームのその後の進行が決定されるとプレーヤはゲームを継続する気力をなくしてしまうものである。 In such a cause, the subsequent progress of the game with biofeedback is determined the player are those would eliminate energy to continue the game. 本発明は、このような実情に鑑み成されたものであって、光ノイズによる誤差誘発信号を検知し、その間の測定データを採用しないようにして、正確に脈拍数を計測する脈拍センサと脈拍計測装置を提供するものである。 The present invention was made in view of such circumstances, and detects the error induced signal due to light noise, so as not adopted during the measurement data, accurate pulse sensor and pulse for measuring the pulse rate there is provided a measuring device.

【0019】次に、図3のタイミング図に従って、持続時間の長いノイズがある場合の動作を説明する。 Next, according to the timing diagram of FIG. 3, the operation when there is a long noise duration. 時間T Time T
1に、脈拍による散乱光Sはなく、外部の光Rがあると受光素子5、受光素子6に同時にノイズNが発生する。 1, the scattered light S not according to the pulse, and the light receiving element 5 has an external light R, the noise N is generated at the same time the light receiving element 6.
第2受光素子6からのノイズNはアンプ12で増幅されてスイッチ14に送られて、スイッチ14はオフとなり、受光素子5からアンプ11、遅延回路13を介しスイッチ14まできたノイズNはここで遮断されてしまう。 The noise N from the second light receiving element 6 is transmitted to the switch 14 is amplified by the amplifier 12, the switch 14 is turned off, from the light receiving element 5 amplifier 11, the noise N was switch 14 Madeki through the delay circuit 13 is here It would be cut off. 従って計算部15には、ノイズが到達しないので、 Thus the calculation unit 15, the noise does not reach,
計算部15の出力波形、正常な脈拍数信号Mはゼロである。 The output waveform of the calculator 15, the normal pulse rate signal M is zero. なお、スイッチ14がオフになったとき、ノイズ検出(オフ)信号が計算部15に出力される。 Incidentally, when the switch 14 is turned off, the noise detection (OFF) signal is output to the calculation unit 15.

【0020】時間T2では、脈拍による散乱光Sがあり、外部の光Rがないので、受光素子5から信号Sが発生し、第2受光素子6にはノイズNが発生しない。 [0020] At time T2, there is the scattered light S by the pulse, there is no external light R, the signal S is generated from the light receiving element 5, the noise N is not generated in the second light receiving element 6. このためスイッチ14は導通状態であり、受光素子5からアンプ11、遅延回路13を介しスイッチ14まできた脈拍信号Sは計算部15に行き、心拍として計測される。 Thus switch 14 is conductive, the pulse signal S from the light receiving element 5 amplifier 11, were the switch 14 Madeki through the delay circuit 13 goes to the calculation unit 15, it is measured as heart rate.
