Introducing Transient Gestures to Improve Pan and Zoom on Touch Surfaces

Introducing Transient Gestures to Improve Pan and Zoom on Touch Surfaces

Abstract

Despite the ubiquity of touch-based input and the availability of increasingly computationally powerful touchscreen devices, there has been comparatively little work on enhancing basic canonical gestures such as swipe-to-pan and pinch-to-zoom. In this paper, we introduce transient pan and zoom, i.e. pan and zoom manipulation gestures that temporarily alter the view and can be rapidly undone. Leveraging typical touchscreen support for additional contact points, we design our transient gestures such that they co-exist with traditional pan and zoom interaction. We show that our transient pan-and-zoom reduces repetition in multi-level navigation and facilitates rapid move- ment between document states. We conclude with a discussion of user feedback, and directions for future research.
