A flying click gesture for unary selection and activation

In some situations a user needs to select or activate a single control when no other controls are plausible candidates. By reducing the precision required to complete the task we can reduce the target acquisistion and activation time. In this paper we descrbe the flying click (flick) gesture and its suitability for the selection and activation of single targets. Through experimental results we demonstrate that the flick gesture is faster and less variable for the selection of unary targets.
