【発明の目的】そこで、本発明の目的は、操作者の注意力の状態に応じて、情報の提示のタイミングが自動的に変化する、注意力測定装置及びこれを用いた情報提示装置を提供することにある。 SUMMARY OF THE INVENTION Therefore, an object of the present invention, provided in accordance with the state of alertness of the operator, the timing of the presentation is changed automatically information, the information presentation apparatus using the attention measuring apparatus and which It is to.

【0008】 [0008]

【課題を解決するための手段】本発明者は、操作者の注意力を測定する技術について研究を重ねた結果、飛越眼球運動の発生頻度と注意力との間に深い関係があることを見い出した。 Means for Solving the Problems The present inventor has repeatedly studied techniques for measuring attention of the operator, found that there is a close relationship between the frequency and the attention of interlaced eye movement It was. 本発明は、この知見に基づいてなされたものである。 The present invention has been accomplished based on this finding.

【0009】飛越眼球運動の発生は、操作者が受ける視覚刺激と関係がある。 [0009] The occurrence of jumps eye movement is related to the visual stimulus the operator receives. 例えば、混雑した市街地での運転など、運転者が通常以上に外界に注意を払っている場合や、外界からの視覚刺激が多い場合には、飛越眼球運動の発生頻度が上昇する。 For example, such as a driver in urban areas crowded, and if the driver is paying attention to the outside world in more than normal, when the visual stimulus from the outside is large, the frequency of occurrence of an interlaced eye movement increases. しかし、運転者が携帯電話を使用している場合や同乗者と会話している場合等の、外界の視覚情報に対する注意力が削がれた状態、又は居眠り発生時等の注意力が低下した状態では、飛越眼球運動の発生頻度が低下する。 However, the driver such as when you are talking or when a passenger who is using a mobile phone, a state in which attention is scraped off against the outside world of the visual information, or attention, such as when dozing occurrence drops in the state, the frequency of occurrence of the jump eye movement is reduced.

【0010】すなわち、本発明に係る注意力測定装置は、このような現象を利用したものであり、操作者の飛越眼球運動を検出する飛越眼球運動検出手段と、この飛越眼球運動検出手段で検出された飛越眼球運動の発生頻度に基づき、前記操作者の注意力レベルを判定する注意力判定手段と、を備えたものである。 [0010] That is, attention measuring apparatus according to the present invention is obtained by utilizing this phenomenon, the interlaced eye movement detecting means for detecting the jumping eye movements of the operator detected by the interlaced eye movement detecting means is based on the occurrence frequency of jumps eye movement was, the attention determination means for determining attentiveness level of the operator, but provided with. 例えば、前記注意力判定手段は、前記発生頻度が低いほど前記注意力レベルが低いと判定する。 For example, the attention judgment unit judges that the attentiveness level the frequency is the lower the lower. 「発生頻度が低いほど注意力レベルが低い」とは、換言すれば、発生頻度が高いほど注意力レベルが高いということである。 The "lower the lower the frequency of occurrence attention level", in other words, attention level the higher the frequency of occurrence is that high.

【0011】本発明に係る情報提示装置は、本発明に係る注意力測定装置を用いたものであり、操作者の飛越眼球運動を検出する飛越眼球運動検出手段と、この飛越眼球運動検出手段で検出された飛越眼球運動の発生頻度に基づき、前記操作者の注意力レベルを判定する注意力判定手段と、この注意力判定手段で判定された注意力レベルに基づき、各種情報の提示のタイミングを決定する各種情報提示手段と、を備えたものである。 [0011] The information presentation apparatus according to the present invention are those with attention measuring apparatus according to the present invention, the interlaced eye movement detecting means for detecting the jumping eye movements of the operator, in this interlace eye movement detecting means based on the occurrence frequency of the detected interlaced eye movement, and attention determination means for determining attentiveness level of the operator, based on the attention level determined in this attention determining means, the timing of the presentation of various information and various types of information presentation means determining, those having a. 例えば、前記注意力判定手段は、前記発生頻度が低いほど前記注意力レベルが低いと判定し、前記各種情報提示手段は、前記注意力判定手段で判定された注意力レベルが低いほど早く情報を提示する。 For example, the attention judgment unit, the attentiveness level the frequency is as low as it is determined to be low, the variety of information presenting means, the fast information the lower the determined attention level by the attention determination means presented.

【0012】ここでいう「注意力レベルが低いほど早く情報を提示する」とは、単に情報を提示する時間を速くするだけではなく、早く情報を提示するために閾値を変更することも含まれ、いうまでもなく、注意力レベルが高いほど遅く情報を提示することも含まれる。 [0012] Here, the term "attention level is to present the lower the early information", not only to speed up the time for presenting the information, are also included to change the threshold in order to present the early information , of course, be included also be presented the late information about attention level is high. この「遅く情報を提示する」には、情報を全く提示しない場合も含まれる。 This "late information to present", is also included if you do not at all present the information. すなわち、本発明は、操作者の眼球運動を電気的又は光学的な手法で計測し、そのな眼球運動の中から飛越眼球運動の頻度を計測して、情報の提示又は非提示の閾値を変動させるものとも言える。 That is, the present invention measures the eye movement of the operator in the electrical or optical method, by measuring the frequency of interlaced eye movement from the eye movement, change the threshold of presentation or non-presentation of information it can be said that those to be.

【0013】脊椎動物の眼球は、レンズ側が正,網膜側が負に帯電している。 [0013] vertebrate eye, the lens side is positive, retinal side is negatively charged. そのため、人体の眼窩周囲の皮膚表面に電極を貼り付けて電位を測定すると、眼球の傾きに比例した上下・左右方向の電位差が観測される。 Therefore, when measuring the potential paste the electrodes to the body of the periorbital skin surface, the potential difference in the vertical and lateral proportional to the slope of the eye is observed. この電位差は、眼電図(Electro-ocurgram、以下「EOG」 This potential difference, EOG (Electro-ocurgram, hereinafter referred to as "EOG"
と略す。 Abbreviated. )と呼ばれる。 ) To be called. 一方、飛越眼球運動は、視線が停留点から急速に移動して次の停留点に止まる現象であり、自動車運転中等の視線の動きに多く見られる。 On the other hand, skipping eye movement, line of sight is a phenomenon that stops to the next stopping point is rapidly moved from the stationary point, often seen in the movement of the line of sight of the car driving moderate. 飛越眼球運動の速度は100 〜500 °/secと非常に大きいため、EOGを高域通過フィルタを通して信号処理することにより飛越眼球運動信号を検出できる。 Because the speed of interlaced eye movement is very large and 100 ~500 ° / sec, it can detect interlaced eye movement signals by the signal processing through a high-pass filter EOG.

【0014】また、飛越眼球運動は、眼球の動きの画像処理、サーチコイル、眼磁図等によっても検出できる。 Further, interlaced eye movements, the image processing of the motion of the eyeball can be detected by the search coil, eye magnetoencephalography like.
眼球の動きの画像処理は、非接触で検出できることが特長であり、角膜反射法が一般的である。 Image processing of the motion of the eye, can be detected in a non-contact is a feature, the corneal reflection method is generally used. 角膜反射法は、 Corneal reflection method,
生体外に置いた光源の角膜反射像の位置と瞳孔中心の位置との差が、眼球回転角に比例することを利用するものである。 The difference between the positions of the pupil center of the cornea reflection image of the light source placed outside the living body, is to utilize a proportional to the eyeball rotation angle.

【0020】図2乃至図4は、図1の情報提示装置の動作を示す波形図である。 [0020] FIGS. 2 to 4 is a waveform diagram showing the operation of the information presentation apparatus of FIG. 以下、図1乃至図4に基づき説明する。 Hereinafter will be described with reference to FIGS.

【0021】飛越眼球運動Eの発生頻度Aは飛越眼球運動信号a 2と基準パルス信号a 1との周期(周波数)の差となって現れ、注意力レベル信号Bは発生頻度Aに反比例する。 The incidence A interlaced eye movement E appears as the difference of the period (frequency) of the interlaced eye movement signals a 2 and the reference pulse signal a 1, attentiveness level signal B is inversely proportional to the frequency A. すなわち、図2に示すように、飛越眼球運動信号a 2の周期が基準パルス信号a 1と同程度であれば、飛越眼球運動Eの発生頻度Aが普通であるので、注意力レベル信号Bは中程度と判定される。 That is, as shown in FIG. 2, if comparable period of interlaced eye movement signal a 2 is the reference pulse signal a 1, since the occurrence frequency A interlaced eye movement E is normally attentiveness level signal B It is determined to be moderate. 図3に示すように、飛越眼球運動信号a 2の周期が基準パルス信号a As shown in FIG. 3, the reference is the period of interlaced eye movement signals a 2 pulse signal a
1よりも短ければ、飛越眼球運動Eの発生頻度Aが多いので、注意力レベル信号Bは高いと判定される。 It is shorter than 1, because there are many frequency A interlaced eye movement E, attentiveness level signal B is determined to be high. 図4に示すように、飛越眼球運動信号a 2の周期が基準パルス信号a 1よりも長ければ、飛越眼球運動Eの発生頻度A Figure 4 As shown in, the longer than interlaced eye movement signal period reference pulse signal a 1 of a 2, the frequency of occurrence of interlaced eye movement E A
が少ないので、注意力レベル信号Bは低いと判定される。 Since less attentiveness level signal B is determined to be lower.

【0022】このようにして判定された注意力レベル信号Bは、各種情報提示手段16に出力される。 [0022] Thus attention level signal is determined by B is output to various kinds of information presenting means 16. 各種情報提示手段16において、電話の着信音や道案内のアナウンス等の、イベントの発生によって操作者Mに提示される情報Cは、それぞれの緊急度や、その処理に要する操作者の負荷量が予め設定されている。 In various types of information presenting means 16, announcements etc. ringtone and directions of the telephone, the information C that is presented to the operator M by the occurrence of an event, each and urgency, the load of the operator required for the process It is set in advance. このときの各種情報提示手段16の動作を、以下に例示する。 The operation of the various types of information presenting means 16 in this case will be exemplified below.

【0023】・イベントの緊急度が高い場合や、負荷量が低い場合には、注意力レベルが高い場合でも、イベント発生を操作者に通知する。 [0023] - If the urgency is high and the event, when the load amount is low, even if the attention level is high, to notify occurrence of an event to the operator. ・イベントの緊急度が低い場合や、負荷量が高い場合には、注意力レベルが一定以上ならば、イベントの発生を操作者に通知しない。 · In the case of a low degree of urgency and events, when the load amount is high, if the attention level is constant or more, not notified of the occurrence of the event to the operator. ・イベント発生を操作者に通知しなかった場合、イベントの性格によって、遅らせて通知するか、無視するかを決定する。 If you did not notice, the event occurrence to the operator, by the nature of the event, or to notify delays, to decide whether to ignore. 例えば、電話の着信は後で通知するが、道案内は通知しない。 For example, an incoming call is to inform later, directions are not notified. ・操作者の注意力レベルが低下している場合は、通常では通知しない緊急度の低い情報も通知する。 • If the operator of the attention level is lowered, low information of urgency that does not notice in normal is also notified. ・自動車の車間距離警報など、測定値と閾値との比較によって運転者に提示される情報については、閾値そのものを注意力レベルに連動して変化させる。 · Automotive vehicle distance warning, the information presented to the driver by comparing the measured value and the threshold is changed in conjunction with the threshold itself attentiveness level. 例えば、飛越眼球運動の発生頻度が高く、運転者が注意を払いながら運転しているような場合を基準として、それよりも飛越眼球運動の発生頻度が下がった場合には、より遠くで車間距離警報を運転者に提示する。 For example, a high frequency of occurrence of jumps eye movement, on the basis of the case, such as the driver is driving while paying attention, if the frequency of occurrence of the jump eye movement falls below it, the inter-vehicle distance in a more distant to present a warning to the driver.

【0025】本実施形態の情報提示装置20では、操作者Mの飛越眼球運動Eを検出する飛越眼球運動検出手段22が、第一実施形態と異なっている。 [0025] In the information providing device 20 of the present embodiment, the interlaced eye movement detecting means 22 for detecting the interlaced eye movement E of the operator M, is different from the first embodiment. 飛越眼球運動検出手段22は、操作者Mの眼球の動きを撮像するCCD Skipping eye movement detecting means 22, CCD imaging the movement of the eyeball of the operator M
