One of the drawbacks of the touch input is limited input vocabulary. To address this problem, we designed a new touch gesture: bounded swipe. Bounded swipe is a swipe gesture that has start and end points inside a target object. We conducted three experiments to test the feasibility of this gesture. The experimental results showed that, when the user swiped normally on a target object, the probability of the accidental occurrence of a bounded swipe was 0.8%. Moreover, the accuracy of bounded swipe was 96.7%. We also investigated the accuracy when distinguishing between a tap and a bounded swipe and found that the two gestures could be distinguished accurately 97.4% of the time.
