Abstract

L'invention concerne un procédé et un appareil de sortie de caractères, le procédé consistant : à recueillir des points de trajectoire d'une trajectoire de déplacement d'un terminal (S102) ; à acquérir un premier paramètre et un second paramètre de déplacement du terminal en fonction des points de trajectoire (S104) ; et à sortir des caractères correspondant au premier paramètre et au second paramètre lorsqu'il y a une correspondance du premier paramètre et du second paramètre avec des paramètres stockés dans le terminal (S106). Grâce au procédé, le problème de mauvaises positions de clic lorsque des caractères sont entrés par des clics sur un écran tactile dans les techniques antérieures, est résolu et, en outre, on obtient l'effet que les utilisateurs peuvent entrer des caractères au moyen de gestes, sans faire fonctionner l'écran.
