Rubbing and Tapping for Precise and Rapid Selection on Touch-Screen Displays

We introduce two families of techniques, rubbing and tapping, that use zooming to make precise interaction on passive touch screens possible. Rub-Pointing uses a diagonal rubbing gesture to integrate pointing and zooming in a single-handed technique. In contrast, Zoom-Tapping is a twohanded technique in which the dominant hand points, while the non-dominant hand taps to zoom, simulating multitouch functionality on a single-touch display. Rub-Tapping is a hybrid technique that integrates rubbing with the dominant hand to point and zoom, and tapping with the nondominant hand to confirm selection. We describe the results of a formal user study comparing these techniques with each other and with the well-known Take-Off and Zoom-Pointing selection techniques. Rub-Pointing and Zoom-Tapping had significantly fewer errors than Take-Off for small targets, and were significantly faster than Take-Off and Zoom-Pointing. We show how the techniques can be used for fluid interaction in an image viewer and in existing applications, such as Google Maps.
