A study on touch & hover based interaction for zooming

Abstract

Proximity is a useful medium for interaction with high interactive digital contents. It can be used in different contexts such as for navigation through depth in 3D space in zoomable interfaces. In this paper, we propose hover-based zoom interaction as an alternative to multi-touch-based zoom interaction, such as expanding/pinching to zoom. It allows users to work rapidly and intuitively at multiple levels of zooming views as their fingertip is hovering over the surface. We evaluated our technique in the context of target search and found that hover-based zoom interaction significantly outperforms the conventional touch-based zoom interaction and touch/hover-based zoom interaction in both objective and subjective measurements: users searched targets more than twice as fast as with the conventional touch-based zoom interaction in our experiment.
