[Problem] To provide a target visual confirmation determination system capable of automatically determining with high accuracy whether a user has visually confirmed a target or not. [Solution] A target visual confirmation determination system 1 is provided with: a display 13 for displaying a target； a line-of-sight detection unit 31 for detecting the line of sight of the user and outputting line-of-sight information relating to the direction of the line of sight； a storage device 55 for recording a log of the line-of-sight information； and a visual confirmation determination unit 40 for determining, on the basis of target position information and the line-of-sight information, whether the user has visually confirmed the target or not, the visual confirmation determination unit 40 being provided with a target approach determination unit 47 for determining whether the line of sight approaches the target or not, and a stare determination unit 48 for determining whether the line of sight remains in the vicinity of a predetermined coordinate position for a predetermined period of time. The visual confirmation determination unit 40 determines that the user has visually confirmed the target in the case where the target approach determination unit 47 determines that the line of sight has approached the target, and the stare determination unit 48 determines that the line of sight remained in the vicinity of the predetermined coordinate position.L'invention concerne un système de détermination de confirmation visuelle cible, apte à déterminer automatiquement avec une grande précision si un utilisateur a confirmé visuellement une cible. Le système de détermination de confirmation visuelle cible (1) selon l'invention comprend : un dispositif d'affichage (13) destiné à afficher une cible； une unité de détection de ligne de mire (31) destinée à détecter la ligne de mire de l'utilisateur et à émettre en sortie des informations de ligne de mire relatives à la direction de la ligne
