Abstract

L'invention concerne un procédé et un dispositif de retour d'intensité de pression sur un écran tactile, et un terminal (700). Le procédé consiste : lorsqu'une opération de pression sur un écran tactile est détectée, à obtenir tout d'abord des données d'intensité de pression correspondant à l'opération de pression et des coordonnées bidimensionnelles de position de pression de l'opération de pression (S101) ; puis à créer un modèle d'espace tridimensionnel au moyen des données d'intensité de pression obtenues et des coordonnées bidimensionnelles de position de pression obtenues (S102) ; et enfin à projeter le modèle d'espace tridimensionnel pour qu'il soit une image bidimensionnelle à afficher sur un écran du terminal (700), de telle sorte que, lorsque l'intensité de pression correspondant à l'opération de pression change, des données d'intensité de pression courante soient retournées de manière dynamique au moyen de l'image bidimensionnelle affichée sur l'écran (S103). Ainsi, grâce à ce procédé et ce dispositif de retour d'intensité de pression sur un écran tactile et au terminal (700), l'intensité de pression est convertie en déformation d'espace à projeter vers l'écran du terminal (700), un effet d'animation tridimensionnelle est présenté sur l'écran du terminal (700), l'utilisateur peut obtenir les changements de l'intensité de pression qu'il exerce lui-même au moyen de l'animation tridimensionnelle affichée sur l'écran du terminal (700) lors de la pression sur l'écran tactile, et l'expérience utilisateur est bonne.
