Abstract

L'invention concerne un dispositif et un procédé d'identification d'iris de suivi de l'œil humain dynamique. Le dispositif comprend un processeur (110), un capteur d'image d'iris (120), un module d'identification de codage d'iris (130), un dispositif de télémétrie (140), un dispositif coulissant (150), un dispositif rotatif (160), une mesa de support d'objet (180), et de multiples dispositifs de capture d'image (170). Le capteur d'image d'iris (120) est disposé sur le dispositif rotatif (160) de façon à tourner lorsque le dispositif rotatif (160) tourne. Le capteur d'image d'iris (120), le module d'identification de code d'iris (130) et le dispositif rotatif (160) sont montés sur la mesa de support d'objet (180). La mesa de support d'objet (180) est disposé sur le dispositif coulissant (150) de façon à se déplacer à mesure que le dispositif coulissant (150) se déplace. Le dispositif ajuste activement le capteur d'image d'iris (120) par l'intermédiaire du dispositif rotatif (160) et du dispositif coulissant (150) pour suivre les yeux d'un utilisateur.
