Patent

CA 2433151

The present invention is directed to a pointing device writing tip comprised of a surface being structured in a manner that while writing with the writing tip on a writing surface (10), the contacts of the writing tip with the writing surface (10) produce different sounds in different directions (14). A hand writing recognition system is provided based on at least the recognition of sounds produced by the writing tip having a surface being structured in a manner that while writing with the writing tip on the writing surface (10), the contacts of the writing tip with the writing surface (10) produce different sounds in different directions (14) for use by the recognition system.

L'invention concerne une pointe d'écriture de stylet composée d'une surface structurée de façon que, pendant l'écriture au moyen de cette pointe sur une surface d'écriture, les contacts de ladite pointe avec ladite surface produisent différents sons dans différentes directions. Elle concerne un système de reconnaissance d'écriture manuelle basé sur au moins la reconnaissance des sons produits par la pointe d'écriture, étant donné que cette dernière possède une surface dont la structure permet de produire différents sons dans différentes directions, sous l'effet du contact de la pointe d'écriture avec la surface d'écriture, ces sons étant reconnus par le système de reconnaissance.
