Abstract

A method for executing a scroll control operation on a touchpad comprises receiving a first contact signal induced by a first contact with a first section of the touchpad, receiving a second contact signal induced by a second contact with a second section of the touchpad, the first section and second section being predefined in a scrolling region on the touchpad, recording a first direction from the first contact to the second contact, and a first distance between the first section and the second section and outputting a scroll control signal to execute a scroll operation, the scroll control signal including information of the first direction and first distance.

Description

technical field [0001] The present invention relates to a control method of a touch device and its device, and specifically discloses a scrolling control method and device thereof applied to a touch device. Background technique [0002] Graphical user interface (Graphical user interface, hereinafter referred to as GUI) is well known to everyone, and a main function of GUI is to allow the window screen of the computer to scroll (including scrolling up and down and scrolling left and right) so that users can browse. Therefore, a graphical control tool called a scroll bar is usually provided on the edge (upper and lower edges or left and right edges) of the computer window, allowing the user to click and drag the mouse to scroll the window screen in a direction parallel to the scroll bar. [0003] At present, due to the advantages of small size, low cost, low power consumption and long service life, touch devices have been widely used in various electronic products to replace o...
