Patent ID: 8751955

Claim:
A computer-implemented method, comprising: detecting two simultaneous sliding user interactions along a display surface of a multitouch input display device axially directed relative to a length of a scrollbar and each proximate to a display location of one of first and second edges of a displayed scroll element of the scrollbar displayed on a graphical user interface (GUI) of the device; concurrently determining: whether the detected two simultaneous sliding user interactions result in a difference in relative spacing between initial user display contact locations and resulting user display contact locations; and whether the detected two simultaneous sliding user interactions also represent movement in similar axial directions axially relative to the length of the scrollbar; automatically zooming available content displayed within the GUI in proportion to any determined difference in the relative spacing between the initial user display contact locations and the resulting user display contact locations, where a detected pinching motion of the detected two simultaneous sliding user interactions closer together zooms in and enlarges a size of displayed portions of the available content and a detected stretching motion of the detected two simultaneous sliding user interactions further apart zooms out and reduces the size of the displayed portions of the available content; and concurrently scrolling the available content in proportion to any determined movement of a center of the scrollbar in the similar axial directions axially relative to the length of the scrollbar.
