摘要： A touchscreen device using a touch trajectory sensing method that determines the moving trajectory of each object being moved into contact with the touch sensing panel and the trajectory sensing area around each touch point according to the movement speed of the respective touch point, where the trajectory sensing area exhibits a positive correlation with the movement speed so that when multiple objects simultaneously contact with the touch sensing panel and then stayed at the respective touch points, or steered on the touch sensing panel, each touch point has a relatively smaller trajectory sensing area at the turning point or retarded point on the touch sensing panel, preventing adjacent touch points at different moving trajectories from falling to the respective opponent second trajectory sensing areas to further eliminate the control unit from making a wrong moving trajectory determination and the touch sensing panel from performing an unexpected touch control operation.
