Abstract
Speed-dependent automatic zooming through content such as documents and images is disclosed. In one embodiment, a method first receives an input, such as a user input on an input device, like a joystick, a mouse, a trackball, or other pointing device. The input is mapped to either speed of navigation through a content space, or scale of the content space while being navigated. The other of speed or scale to which the input was not mapped is then determined, based on the relationship that scale times speed equals a constant. The content space is then navigated, based on the speed or scale mapped from the input, and the scale or speed determined.
