Definitions

  • the keypad of the modern mobile terminal has decreased in size while the number of keys or buttons presented to the user has increased. Since the keypad is limited in its miniaturization by ergonomic considerations, the number of buttons available may effectively limit the number of features that can be integrated into the mobile terminal. Partially in response to the crowded keypad, and additionally for enhanced ergonomics, it is known in the mobile terminal industry to locate control buttons separately from the mobile terminal's keypad. In particular, it is known to provide a pair of spaced apart control buttons on one side of the mobile terminal. These buttons, often marked with "up” and “down” indicia, typically serve to increase or decrease, respectively, the volume level of the mobile terminal's speaker. Some mobile terminals additionally utilize these buttons to scroll the menu display up or down when a call is not in progress.
  • buttons improve the mobile terminal's ergonomics and ease of use in two ways.

Abstract

Un terminal mobile, tel qu'un radiotéléphone cellulaire, comporte deux boutons de commande espacés sur le côté de l'appareil, qui permettent de régler une pluralité de fonctions réglables. Dans une forme de réalisation, lorsqu'un appel est en cours d'établissement, on peut régler le volume du haut-parleur en appuyant sur l'un des boutons de commande ; un seul clic simultané des deux boutons actionne la commande silencieux du microphone ; et un double clic simultané des deux boutons règle le volume du haut-parleur au niveau maximum. Lorsqu'aucun appel n'est en cours, on peut faire dérouler un écran menu en appuyant sur l'un des boutons ; un seul clic simultané des deux boutons supprime un choix de menu en surbrillance ; et un double clic simultané des deux boutons permet de sélectionner un choix de menu en surbrillance. Ce système confère à l'utilisateur une commande plus complète des paramètres de fonctionnement du terminal mobile pendant un appel, sans interruption de l'appel par un changement de position de fonctionnement du terminal, et permet d'explorer les menus à l'aide d'une seule main lorsqu'aucun appel n'est en cours.
