Abstract

L'invention concerne un dispositif de navigation de document, un procédé d'affichage de document et un programme d'affichage de document avec lesquels un utilisateur peut facilement comprendre les parties auxquelles il faut faire attention et la manière dont un écran a bougé. Des données de gestion de positions de défilement sont préparées dans une mémoire (SV2) ; lesdites données de gestion de positions de défilement gèrent une plage d'affichage et une région d'attention pour chaque position d'arrêt de défilement dans un contenu à afficher. Puis, pour chaque position d'arrêt de défilement, la région d'attention est affichée pour être différenciable des autres régions, en fonction des données de gestion de positions de défilement (SV16). Par exemple, si une instruction de défilement est reçue d'un utilisateur (SV10), le document défile sur la plage d'affichage pour la position d'arrêt de défilement suivante, tout en maintenant la région d'attention pour la position d'arrêt de défilement actuelle différenciable des autres régions (SV32–SV36).
