Abstract: In one example, a method includes receiving an indication of an input gesture detected at a presence-sensitive input device, where the input gesture includes one or more input points and each input point is detected at a respective location of the presence-sensitive input device. The method may also include determining a focal point of the input gesture, and determining a radius length. The method may also include determining a shape centered at the focal point and having a size determined based on the radius length. The method may also include responding to a change in a geometric property of the shape by scaling information included in a graphical user interface, where the scaling of the information being centered at the focal point.

Abstract: Methods and apparatus for displaying display windows in a graphical user interface are disclosed. An example method includes opening, on a computing device, a first root browser window and spawning, from a first link in the first root browser window in response to a user toss-gesture associated with the first link, a first subordinate browser window. The example method further includes displaying, in a hierarchical display feature of the computing device, a hierarchical relationship between the first root browser window and the first subordinate browser window so as to visually indicate hierarchical subordinacy of the first subordinate browser window to the first root browser window.
