Abstract

L’invention concerne un dispositif d’entrée à clavier virtuel et un procédé de focalisation multi-entrées, lesquels relèvent du domaine de la sécurité des informations. Le dispositif comprend un module de commande maître et un module de clavier virtuel. Le procédé comprend les étapes suivantes : on affiche un clavier virtuel et une pluralité d’unités d’entrée/sortie de simulation et régle les marques de focalisation correspondantes en un mode d’entrée de clavier virtuel; un utilisateur clique sur une unité d’entrée/sortie de simulation, et le module de commande maître règle la marque de focalisation d’entrée courante comme étant la marque de focalisation de l’unité; un utilisateur clique sur le clavier virtuel et on détermine le caractère correspondant en fonction de la position d’un curseur par le module de clavier virtuel, si le caractère est un caractère de clavier, on met en cache le caractère de clavier et on envoie un message de clavier virtuel au module de commande maître par le module de clavier virtuel, et après réception du message de clavier virtuel, on informe l’unité d’entrée/sortie de simulation qui correspond à la marque de focalisation d’entrée courante de la réception du caractère de clavier par le module de commande maître; si le caractère est un caractère d’état, on effectue le traitement d’état correspondant sur le clavier virtuel à l’aide du module de clavier virtuel. Le dispositif d’entrée de clavier virtuel et le procédé de focalisation multi-entrées améliorent la sécurité d’une entrée par clavier virtuel.
