CA 2557063

The invention relates to a man/machine interface which enables music software programs to be controlled using a touch screen to manipulate virtual objects. More specifically, the invention relates to a method of controlling a piece of computer equipment using a device comprising a multi-contact two-dimensional sensor for the acquisition of tactile information and computing means which generate control signals as a function of said tactile information. The invention is characterised in that the method comprises a step involving the generation of graphical objects on a screen that is positioned under a transparent tactile sensor, each of said graphical objects being associated with at least one specific processing principle. According to the invention, during each acquisition phase, the sensor delivers a plurality of tactile information, whereby each piece of tactile information undergoes specific processing determined by the location thereof in relation to the position of one of said graphical objects.

La présente invention se rapporte à une interface homme-machine permettant le contrôle de logiciels de musique par un écran tactile avec manipulation d'objets virtuels. Elle concerne un procédé pour le contrôle d'un équipement informatisé par un dispositif comportant un capteur bidimensionnel multi- contact pour l'acquisition d'informations tactiles, ainsi que des moyens de calculs générant des signaux de commande en fonction desdites informations tactiles caractérisé en ce qu'il comporte une étape de génération d'objets graphiques sur un écran placé sous un capteur tactile transparent, chacun des objets graphiques étant associé à au moins une loi de traitement spécifique, le capteur délivrant lors de chaque phase d'acquisition une pluralité d'informations tactiles, chacune desdites informations tactiles faisant l'objet d'un traitement spécifique déterminé par sa localisation par rapport à la position d'un desdits objets graphiques.
