Bounded Swipe: Swipe Gesture Inside a Target

Abstract

Touch input has the problem that the input vocabulary is limited. In this paper, we propose the bounded swipe as a new touch gesture for solving this problem. In the bounded swipe, which extends the commonly used swipe action, the start and end points are inside a target. To test the feasibility of this gesture, we first investigated whether a bounded swipe is ever performed accidentally when a user swipes normally on a target; in 99.2% of swipes performed, the end point of the swipe was outside the target. Under the bounded swipe, the success rate was 96.7%. Therefore, the bounded swipe is a touch gesture that does not conflict with the conventional swipe.
