<p>A touch tracking method for the touch screen is provided. A touch tracking method for a touch track on a touch screen comprises the steps of: defining a touch track function by information of detected touch points; calculating a predicted touch point by said touch track function; determining if a next detected touch point is located in a preset scope of said predicted touch point; and if the next detected touch point is located in the preset scope of the predicted touch point, outputting the predicted touch point as an output touch point. A touch tracking device for a touch track on a touch screen is also provided. The touch tracking device for the touch screen can, not only determine relationship between detected touch points at different detected times to draw the touch tracks, but can also make the touch track smooth and help eliminate noise point effectively.</p> |
