【 摘 要 】

We extend Forlines et al.'s idea of mixed absolute and relative ;;HybridPointing;; to large multitouch displays. In our bimanual ;;CursorTap;; interaction technique, one hand triggers a kinaesthetic relative pointing mode while the other controls a distant cursor similar to a large touchpad. A controlled experiment compares CursorTap to standard absolute touch input, and a ;;Drag;; technique, where all display content may be dragged to the user. Our results show CursorTap is fastest when accessing distant targets and returning to nearby targets, a common usage scenario. Overall, the measured selection times across distances is nearly flat for CursorTap, but linearly increases for the absolute and Drag techniques. As further validation, a second study explores how CursorTap is used in a more open setting. We developed a two-person game to create opportunities to use CursorTap under cooperative and competitive settings. The results demonstrate a willingness to use CursorTap, and reveal situations and input modalities where usage is most likely.
