The design and evaluation of multi-finger mouse emulation techniques
Justin Matejka, Tovi Grossman, Jessica Lo, George W. Fitzmaurice · 2009
We explore the use of multi-finger input to emulate full mouse functionality, such as the tracking state, three buttons, and chording. We first present the design space for such techniques, which serves as a guide for the systematic investigation of possible solutions. We then perform a series of pilot studies to come up with recommendations for the various aspects of the design space. These pilot studies allow us to arrive at a recommended technique, the SDMouse. In a formal study, the SDMouse was shown to significantly improve performance in comparison to previously developed mouse emulation techniques.
