Title
(EN) METHOD AND SYSTEM FOR COMPUTER ACCESS AND CURSOR CONTROL USING A RELIEF OBJECT IMAGE GENERATOR
(FR) TECHNIQUE ET SYSTEME PERMETTANT UN ACCES INFORMATIQUE ET UNE COMMANDE DE CURSEUR AU MOYEN D'UN GENERATEUR D'IMAGES OBJETS EN RELIEF
Abstract
(EN) A system and method for using a relief object image generator for cursor control, computer access control, and operational parameter control is disclosed. The system includes a relief object image generator (10), a sensor array (72), an image processor, and a memory. The relief object image generator (10) generates images of relief objects, such as fingerprints, brought in proximity of the exposed surface of the image generator (10). The image processor receives the image from the sensor array (72), processes the image, and compares the resulting descriptive information to stored information corresponding to authorized users. If a match is found, the user is granted access to the computer. The image processor may also process the image to determine image movement or the image's presence or absence. Detected movement is used to generate directional signals while the presence and absence of the image is used to generate highlight and select signals. These signals conform to those generated by known mouse devices so the system of the present invention can replace a position variable device in the keyboard of a laptop or other portable computer without sacrificing functionality for the system. Other uses of the system disclosed herein include control of operational parameters for a device such as brightness and contrast for a monitor and the transmission of relief object images to remote sites for authentication of a user.
(FR) Cette invention a trait à un système ainsi qu'à la technique afférente visant à l'utilisation d'un générateur d'images objets en relief aux fins de la commande d'un curseur, du contrôle d'accès et de la commande de paramètres d'exploitation. Le système comporte un générateur d'images objets en relief (10), une mosaïque de détecteurs (72), un processeur d'images et une mémoire. Le générateur d'images objets en relief (10) produit des images d'objets en relief, des empreintes digitales notamment, amenés à proximité de sa face à découvert. Le processeur d'images reçoit l'image émanant de la mosaïque de détecteurs (72), la traite et compare l'information descriptive obtenue avec une information mémorisée correspondant à des utilisateurs autorisés. S'il y a concordance, l'utilisateur se voit donner accès à l'ordinateur. Le processeur d'images peut également traiter l'image pour détecter un mouvement d'image ou vérifier la présence ou l'absence d'image. Le mouvement détecté est utilisé pour produire des signaux de direction alors que la détection de la présence et de l'absence de l'image permet de produire des signaux de mise en évidence et de sélection. Ces signaux concordent avec ceux que produisent les souris classiques de sorte que ce système est à même de remplacer un dispositif de variable de position se trouvant dans le clavier d'un ordinateur bloc-notes ou d'un autre ordinateur portable sans perte de fonctionnalité. Parmi d'autres utilisations décrites par cette invention, figurent la commande de paramètres d'exploitation d'un dispositif, tels que la luminosité ou les contrastes d'un écran, ainsi que l'émission d'images objets en relief à destination de sites à distance aux fins d'une authentification d'utilisateur.
