Abstract

L'invention porte sur un procédé de sélection d'objets pouvant être combinés pour former un texte court tel que par exemple un message figurant sur l'écran d'un appareil téléphonique. Lesdits objets se voient attribuer une combinaison unique des éléments suivants: un trait oblique (/), un tiret horizontal (-), un trait vertical (l), une courbe ouverte (C) et une courbe fermée (O). Un premier élément (301) est introduit. Tous les objets comportant ce premier élément sont présentés (303) suite à une recherche (302) dans une table de conversion. Des étapes d'introduction de nouveaux éléments (310), de recherche d'objets (302) comprenant l'élément introduit, de présentation d'objets possibles (303) se poursuivent jusqu'à l'introduction d'une combinaison complète (304) d'éléments. Lorsque la combinaison complète correspondant à un objet a été introduite, l'objet est inscrit (305). L'utilisateur confirme que l'objet inscrit correspond à l'objet désiré après quoi l'objet est inclus dans le texte (307). Si un autre objet (308) doit être inclus dans le texte, on introduit un nouveau premier élément. Le processus se poursuit jusqu'à obtention du texte désiré.
