Abstract

L’invention concerne un dispositif terminal mobile compact comprenant un nombre relativement important de petits pavés numériques regroupés serrés dans un panneau constituant le dispositif terminal mobile pourvu d’un moyen permettant à un utilisateur de se servir facilement des petits pavés numériques du bout des doigts, le dispositif terminal mobile se heurtant traditionnellement au problème d'utilisation des pavés numériques du bout des doigts même avec une reconnaissance des caractères au niveau des pavés numériques. Suivant le principe consistant à séparer la reconnaissance du bout des doigts de la reconnaissance des caractères sur les pavés numériques, le dispositif terminal mobile est pourvu d'un moyen permettant de changer de manière continue la brillance des couleurs entre des pavés numériques voisins essentiellement sous forme de vague et de rendre la brillance des couleurs des caractères sur les pavés numériques différente de la brillance des couleurs des pavés numériques proprement dits. Cela permet une utilisation plus ergonomique visuellement et optiquement. Le dispositif terminal mobile améliore encore la convivialité en définissant une zone de pavé numérique afin de recevoir en caractère en forme de diamant. En variante, on renforce la convivialité grâce à un moyen permettant de changer la hauteur d’un pavé numérique et la hauteur d’un pavé numérique voisin, constituant un groupe de pavés numériques, de manière continue et alternée sous forme de vague.
