The Design and Evaluation of Multi-Finger Mouse Emulation Techniques

AbstractWe explore the use of multi-finger input to emulate fullmouse functionality, such as the tracking state, threebuttons, and chording. We first present the design space forsuch techniques, which serves as a guide for the systematicinvestigation of possible solutions. We then perform aseries of pilot studies to come up with recommendations forthe various aspects of the design space. These pilot studiesallow us to arrive at a recommended technique, theSDMouse. In a formal study, the SDMouse was shown tosignificantly improve performance in comparison topreviously developed mouse emulation techniques.
