Abstract
A touchpad includes a controller connected to a touch sensor. The controller detects the fingers touching on the touch sensor to determine to start up and terminate a scroll bar control function. In the scroll bar control function, the movement of the finger or fingers touching on the touch sensor is detected for scrolling on a window, and the vertical distance and the horizontal distance of the movement are evaluated for determining the scrolling amount of a vertical scroll bar or a horizontal scroll bar of the window.
