Virtual controllers for visual displays are described. In one implementation, a camera captures an image of hands against a background. The image is segmented into hand areas and background areas. Various hand and finger gestures isolate parts of the background into independent areas, which are then assigned control parameters for manipulating the visual display. Multiple control parameters can be associated with attributes of multiple independent areas formed by two hands, for advanced control including simultaneous functions of clicking, selecting, executing, horizontal movement, vertical movement, scrolling, dragging, rotational movement, zooming, maximizing, minimizing, executing file functions, and executing menu choices.

L'invention concerne des dispositifs de commande virtuelle d'affichages visuels. Dans une mise en AEuvre, un appareil photo saisit l'image de mains sur un arrière-plan. L'image est segmentée en zones de main et en zones d'arrière-plan. Les divers gestes de la main et des doigts isolent des parties de l'arrière-plan dans des zones indépendantes, auxquelles sont alors affectés des paramètres de commande pour manAEuvrer l'affichage visuel. Il est possible d'associer de multiples paramètres de commande aux attributs de multiples zones indépendantes formées par deux mains, pour une commande avancée comprenant des fonctions simultanées de clic, de sélection, d'exécution, de mouvement horizontal, de mouvement vertical, de défilement, de déplacement, de mouvement de rotation, de zoom, d'agrandissement, de réduction, d'exécution de fonctions de fichiers, et d'exécution de choix de menu.
