Abstract:
(EN) An eye blink detection device determines that an eye blink has occurred (ST19) when the following conditions are satisfied: (1) detection of a lower peak (ST13) after an upper peak is detected in the ocular potential (ST12); (2) detection of the absolute value of a first mean value VA1 of ocular potential for detection during a first period before the upper peak (ST14) and of the absolute value of a second mean value VA2 of ocular potential for detection during a second period after the upper peak (ST15), and determination that VA1 is larger than VA2 (ST16); and (3) determination that the slope D of the upper-lower peak is steeper than a prescribed reference slope (ST18).
(FR) La présente invention concerne un dispositif de détection de battements des paupières qui détermine qu'un battement des paupières s'est produit (ST19) lorsque les conditions suivantes sont satisfaites: (1) la détection d'un pic inférieur (ST13) après la détection d'un pic supérieur dans le potentiel oculaire (ST12); (2) la détection de la valeur absolue d'une première valeur moyenne VA1 de potentiel oculaire pour la détection pendant une première période avant le pic supérieur (ST14) et de la valeur absolue d'une seconde valeur moyenne VA2 de potentiel oculaire pour la détection pendant une seconde période après le pic supérieur (ST15), et la détermination que VA1 est supérieure à VA2 (ST16); et (3) la détermination que la pente D du pic supérieur-inférieur est plus abrupte qu'une pente de référence prescrite (ST18).
(JA) (1)眼電位の上ピークを検出した(ST12)後に下ピークを検出する(ST13)こと、(2)上ピークの前の第1の期間内における検出用眼電位の第1の平均値の絶対値VA1(ST14)と、上ピークの後の第2の期間内における検出用眼電位の第2の平均値の絶対値VA2(ST15)を検出し、VA1がVA2より大きいと判断されたこと(ST16)、且つ、(3)上下ピーク傾きDが所定の基準傾きより急峻であると判断された(ST18)、という条件を満たした場合に瞬目であると判定する(ST19)。
