Abstract

Système d'aide au dessin qui améliore un croquis dessiné par l'utilisateur, en l'occurrence un document électronique dans un système informatique, en recueillant les données sur un ou plusieurs traits du croquis pendant que l'utilisateur dessine. Les données sur les traits comprennent de l'information temporelle et des caractéristiques de chaque trait. Les traits sont traités en fonction de l'information temporelle, puis analysés en fonction des traits déjà traités en fonction de l'information temporelle. Le croquis est amélioré en fonction des résultats de l'analyse.
