Abstract

L'invention porte sur un dispositif d'ordinateur stylo de bureau qui enregistre le trajet de déplacement d'un outil d'écriture pour stocker le trajet de déplacement en tant que données électroniques simplement par écriture d'une note directement sur une feuille de papier placée à l'intérieur d'un cadre avec l'outil d'écriture. Ce dispositif d'ordinateur stylo de bureau comprend un outil d'ordinateur stylo de bureau et un capteur optique comprenant au moins une paire d'éléments d'émission de lumière et de réception de lumière montés sur un cadre rectangulaire. Le capteur optique détecte l'interception de faisceaux de lumière se propageant de l'élément d'émission de lumière à l'élément de réception de lumière, qui est provoquée par l'outil d'écriture à l'intérieur du cadre, pour émettre ainsi des informations concernant la position de l'outil d'écriture. Lorsqu'une opération d'écriture est réalisée sur une feuille de papier révélée à l'intérieur du cadre de ce capteur optique, le trajet de déplacement de la pointe de l'outil d'écriture est stocké en tant que données électroniques dans un moyen de stockage.
