Abstract

L'invention concerne un procédé et un dispositif de traitement de données de commande tactile, un dispositif intelligent et un support d'informations se rapportant au domaine des dispositifs intelligents. Le procédé consiste : à détecter un événement tactile d'un stylet d'écriture sur un écran tactile, le stylet d'écriture constituant un dispositif conforme à la catégorie HID USB ; à reconnaître le nombre de stylets d'écriture ; si le nombre est supérieur ou égal à 2, à utiliser le protocole multi-tactile HID pour encapsuler des données de commande tactile constituant des données déclenchées par l'événement tactile ; à envoyer les données tactiles encapsulées à un système d'exploitation, le système d'exploitation constituant un système d'exploitation du dispositif intelligent subordonné au signal d'affichage en cours de l'écran tactile. Le mode de réalisation de la présente invention permet de résoudre le problème d'écriture d'erreurs de reconnaissance dû à l'utilisation simultanée d'au moins deux stylets d'écriture, et d'améliorer la précision de reconnaissance lorsque plusieurs stylets d'écriture sont utilisés simultanément.
