In a method for scroll bar control on a touchpad, the fingers touching on the touchpad are detected 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 touchpad 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.

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.

A capacitive touchpad provides operational modes including key input, graphical input, handwriting input, and mouse control. The touchpad comprises a panel having several programmed regions thereon, several patterns in the regions are programmed for the operational modes, and a pattern on the panel is programmed as a mode switch to switch the touchpad between the operational modes. In the graphical input mode, the regions include a graphical input region for graphical input. In the key input mode, the patterns include ones for keys to simulate a keyboard. In the handwriting input mode, the regions include a handwriting region for handwriting input. In the mouse control mode, the regions include a cursor control region as well as horizontal and vertical scroll regions.

A touch scroll mouse with orientation sensation comprises a touchpad providing a scroll bar function. The touchpad comprising a plurality of orientation structures, these orientation structures including barriers, protuberant or concave lump structures, protuberant transverse structures or transverse nicks, supplying the users to tell if their finger touch the auto-scrolling regions or determine their slide distance and direction.
