Abstract
To overcome the physical limitation of the display screen size, some computing devices may use the display screen as a window to show a subset of a larger “virtual desktop”. For example, a laptop with an 800×600 pixel display may show a subset of a 1280×1024 pixel virtual desktop. The user then manipulates scrollbars on the sides of the display to move the window to the portion of the virtual desktop he wishes to view. The display screen may pose a particular problem for personal digital assistants (PDAs), cell phones, and other handheld devices which have relatively small displays. A hand held device of the present disclosure is its own mouse, such that a virtual desktop may be navigated by moving the device itself to display desired portions of the virtual desktop on the screen of the device.
