CA 2280823

A transmitter device is disclosed for use with a conventional pen in which the ultrasound transmitter is a cylindrical element lying coaxial with the pen and adjacent to its tip, and a jointed eraser structure. Conventional triangulation techniques are used to track the position and motion of a writer or eraser. An encoding facility associated with the pen provides the ability to distinguish whether the pen is used for marking or as an erasing implement, as well as determining the nature or character of written line width or eraser swath. A data stream thus generated can be used in a variety of ways, such as, for example, to feed information into the memory of a digital computer, and/or to feed information for transmission to remote stations.

La présente invention concerne un dispositif émetteur, conçu pour être utilisé avec un stylo classique, dans lequel un émetteur d'ultrasons est un élément cylindrique disposé de manière coaxiale avec le stylo et adjacent à sa pointe, et une structure d'effacement associée. On utilise des techniques de triangulation classiques pour détecter la position et le mouvement d'écriture ou d'effacement. Une fonction de codage associée au stylo permet de faire la distinction entre l'utilisation de celui-ci en tant que dispositif de marquage ou en tant que dispositif d'effacement et permet de déterminer la nature ou le caractère de la largeur de ligne écrite, ou la surface balayée par le dispositif d'effacement. Un flux de données ainsi généré peut servir de diverses manières, comme par exemple, pour envoyer des informations dans la mémoire d'un ordinateur numérique et/ou pour envoyer des informations à des stations à distance.
