  • Touch-sensitive displays offer several advantages e.g. they allow users to make user inputs and selections by directly touching the displayed item. Therefore, touch- sensitive display offer users a very intuitive and user friendly way of interacting with the electronic device.
  • Keyboards/Keypads on electronic devices can be of various types and may comprise various lay-out arrangements.
  • Touch-sensitive displays are e.g. also used as keyboard/keypad. This is convenient because it removes the need for a dedicated hardware keyboard.

  • the keys must inherently be very small to fit the entire keyboard, including all the alphabetic letters, on the display area and therefore the user may find it difficult to hit the correct key and not a nearby key. This makes the use of the touch-sensitive display as keyboard/keypad less convenient and somewhat unreliable.

Abstract

L'invention concerne un dispositif électronique (100) et un procédé de fonctionnement d'un dispositif électronique (100), le dispositif électronique (100) comprenant une unité d'affichage tactile (104, 300), une unité de traitement (301) et un environnement d'interface utilisateur graphique comprenant des touches (401) pour une saisie par l'utilisateur. Premièrement, un premier sous-groupe de touches est sélectionné parmi un groupe de touches, à l'aide de l'unité de traitement (301), la sélection étant fondée sur l'utilisation relative des touches. Ensuite, le premier clavier (403) comprenant le premier sous-groupe de touches est affiché, sur l'unité d'affichage tactile (104, 300). En outre, à l'aide de l'unité d'affichage tactile (104, 300), une détection a été effectuée d'un contact avec l'unité d'affichage tactile (104, 300) pendant que le premier clavier (403) est en train d'être affiché et si le contact détecté correspond à un geste prédéfini, un second clavier (404) comprenant un second sous-groupe de touches parmi le groupe de touches est affiché sur l'unité d'affichage tactile (104, 300). Les touches sont sélectionnées de telle sorte que des touches incluses dans le premier sous-groupe de touches ont une plus grande utilisation relative que les touches incluses dans le second sous-groupe de touches.
