  • Patent number: 7760189
    Abstract: A method and system for providing diagonal scrolling on a touchpad of a device is disclosed. The method and system comprises determining if at least one finger is in contact with the touchpad, and entering a diagonal scroll mode if more than one finger is in contact with the touchpad. A system and method in accordance with the present invention allows the user to initiate a diagonal scroll at any location on a touchpad by using two fingers, thereby greatly enhancing the functions of the touchpad and allowing the user to manipulate computer programs from the touchpad much more efficiently and easily. The present invention supports diagonal scrolling on a touchpad and does not require a precise location for vertical or horizontal scrolling, since the entire touchpad area/surface can be used.
