RubberEdge: Improved Interaction with Mobile Devices via Elastic-Edged Touchpads

Abstract

Pointing is a fundamental part of using any computer system. The computer mouse is probably the most efficient pointing device when using a desktop computer, but it is not always practical for mobile devices such as laptops or personal hand-held computers. Many laptops instead include a rectangular surface called a touchpad, on which the user moves their finger to move the display pointer a corresponding distance and direction. However, the limited area of the touchpad, together with the increasing size and resolution of laptop displays, makes it easy to run out of space when making large movements. When this happens, the user needs to lift their finger, move backwards, and then press down again to continue the movement. This is called clutching, and it often has to be done several times to reach distant objects. Clutching hurts performance because the pointer stops moving during each clutching action.
