Abstract

Un affichage tête haute est monté dans un objet mobile tel qu'un véhicule, produit une image virtuelle, par exemple devant un pare-brise et affiche une image par superposition de l'image virtuelle sur un paysage devant l'objet mobile. Sur un moyen d'affichage est affichée une image dans laquelle une icône indiquant un objet d'affichage présent autour de la position actuelle de l'objet mobile est affichée de manière à indiquer une direction dans laquelle l'objet d'affichage est présent, la position actuelle de l'objet mobile servant de référence. Le moyen de commande d'affichage entraîne l'affichage d'informations de caractère qui indiquent des informations correspondant à l'icône par des caractères de manière à correspondre à l'icône lorsque l'objet mobile est arrêté, et n'entraîne pas l'affichage des informations de caractère lorsque l'objet mobile se déplace. En conséquence, on peut éviter à un conducteur d'être distrait par les informations de caractère affichées pendant qu'il conduit.
