| Abstract: | We present a simple finger registration technique that can distinguish in real-time which hand and which fingers of the user are touching the touchscreen. The finger registration process is activated whenever the user places a hand in any orientation anywhere on the touchscreen. Such a finger registration technique enables the design of multitouch interfaces that directly map combinations of user's fingers to the interface's operations. As an initial study, we demonstrate the usability of our finger registration method in a simple application. Specifically, we design a virtual mouse interface that enables the user to perform mouse operations in a relax manner, with fingers naturally curved and the idling fingers allowed to rest comfortably, like using a physical mouse or trackball. The ability to distinguish individual contact fingers will open a new avenue for designing richer multi-touch interfaces. |
