Abstract
(EN)
A method and a device for identifying irregular points of a touch screen are provided. The method involves: setting a buffer queue (100); and storing coordinate data of periodic continuous sampling points into the buffer queue, and identifying whether there are irregular points in the more than four continuous sampling points based on the stored coordinate data of the more than four continuous sampling points (101). The method and the device can find out the irregular points in the track of the touch screen, and further filter and remove the irregular points.
(FR)
Une méthode et un dispositif d'identification de points irréguliers d'un écran tactile sont divulgués. La méthode consiste à : créer une file d'attente tampon (100); stocker les coordonnées de points d'échantillonnage continu périodique dans la file d'attente tampon et identifier la présence de points irréguliers dans au moins quatre points d'échantillonnage continu, en fonction des coordonnées stockées desdits au moins quatre points d'échantillonnage continu (101). La méthode et le dispositif de l'invention permettent de trouver les points irréguliers dans les pistes de l'écran tactile, de filtrer et d'éliminer les points irréguliers.
