Bimanual and Unimanual Image Alignment: An Evaluation of Mouse-Based Techniques

Authors: Celine Latulipe, Craig S. Kaplan, and Charles L.A. Clarke

Abstract: We present an evaluation of three mouse-based techniques for aligning digital images. We investigate the physical image alignment task and discuss the implications for interacting with virtual images. In a formal evaluation we show that a symmetric bimanual technique outperforms an asymmetric bimanual technique which in turn outperforms a unimanual technique. We show that even after mode switching times are removed, the symmetric technique outperforms the single mouse technique. Subjects also exhibited more parallel interaction using the symmetric technique than when using the asymmetric technique.
