Multi-Tapping Shortcut: A Technique for Augmenting Linear Menus on Multi-Touch Surface

摘要

In this paper, we propose the Multi-Tapping Shortcut (MTS), a technique aimed at augmenting linear menus on multi-touch surfaces. We designed this multi-finger two-handed interaction technique in an attempt to overcome limitations of direct pointing on interactive surfaces while maintaining compatibility with traditional interaction techniques. Multi-tapping Shortcuts exploit multi-tapping by simply tapping a finger on the surface several times. This report describes the results of an experimental evaluation of our technique, with comparison to the Radial Stroke Shortcut (RSS) technique. Results show that the mean task completion time with MTS is 21.7% faster than that with RSS. MTS also outperformed RSS in terms of error and some users' assessments of comfort.
