Tapping on the same point twice is a common operation known as double tap, but tapping on distant points in sequence is underutilized. We explore the potential uses of consecutive distant tap operations, which we call Ta-Tap. As a single-touch operation, it is expected to be particularly useful for single-handed touch screen use. We examined three possible uses of Ta-Tap: simulating multi-touch operations, invoking a virtual scroll wheel, and invoking a pie-menu. We verified the feasibility of Ta-Tap through the experiment.
