Abstract

L'invention concerne une configuration de touches pour clavier tactile et un procédé d'utilisation associé. La configuration de l'invention peut être adaptée à des produits numériques portables tels qu'un téléphone cellulaire. Selon la configuration de l'invention, les touches mécaniques sont essentiellement placées sous le clavier tactile, et destinées à remplir une fonction d'appel. La touche mécanique, qui est mise en oeuvre par des tranches métalliques élastiques, peut être détectée comme une touche lorsqu'elle ressort, grâce à la tranche métallique. La tranche métallique permet en outre d'ajouter des fonctions de navigation, de commande de souris, de navigateur multimédia et autres. Les tranches métalliques se trouvant dans une couche différente de celle du clavier tactile, les opérations de base précitées sont mises en oeuvre par le biais des caractères du clavier tactile, tandis que la fonction de confirmation est mise en oeuvre par le biais de la tranche métallique, permettant à l'utilisateur de terminer l'opération à une seule main. L'invention améliore par conséquent la sensibilité tactile et le maniement à une seule main.
