Abstract

L'invention concerne un dispositif d'entrée qui permet à un utilisateur d'introduire des données par l'intermédiaire d'un clavier virtuel représenté par une image affichée. Le dispositif d'entrée comprend: des moyens de spécification de touche qui spécifient une touche appuyée sur le clavier virtuel; des moyens de prédiction de touche qui prédisent une touche candidate à appuyer, après la touche spécifiée par les moyens de spécification de touche; et des moyens de traitement d'affichage qui modifient l'état d'affichage de la touche candidate. L'invention facilite l'introduction de données au moyen du clavier virtuel représenté par l'image affichée.
