Abstract

L'invention concerne un procédé et un dispositif de sélection circulaire pour des caractères chinois manuscrits, un appareil tactile et un support d'informations lisible. Le procédé de sélection circulaire pour des caractères chinois manuscrits consiste : à surveiller une opération de sélection circulaire effectuée sur une écriture manuscrite cible sur une interface d'affichage (S21); à relier des points de contact détectés pendant l'opération de sélection circulaire et à générer une trajectoire de mouvement fermée correspondant à l'opération de sélection circulaire (S22); à déterminer, en fonction d'un point d'intersection entre une ligne droite correspondant à chaque point d'écriture manuscrite de l'écriture manuscrite cible et la trajectoire de mouvement fermée et un angle de trajectoire correspondant à chacun des points d'intersection entre eux, si chaque point d'écriture manuscrite est situé à l'intérieur de la trajectoire de mouvement fermée, la ligne droite correspondant à chaque point d'écriture manuscrite étant une ligne droite passant à travers les points d'écriture manuscrite (S23); à déterminer, en fonction du nombre calculé de points d'écriture manuscrite situés à l'intérieur de la trajectoire de mouvement fermée, si l'écriture manuscrite cible est située à l'intérieur de la trajectoire de mouvement fermée (S24); s'il est déterminé que l'écriture manuscrite cible est située à l'intérieur de la trajectoire de mouvement fermée, à encercler et à sélectionner l'écriture manuscrite cible (S25). Le procédé réduit la difficulté de l'utilisateur lors de la sélection d'un caractère chinois manuscrit sur un écran, ce qui permet d'améliorer l'expérience de l'utilisateur.
