为了简化大型显示器上远程目标的选择，本文提出了一种新的技术称为ShifTable。使用ShifTable，用户将手指或笔移向所需的目标，携带目标的整个屏幕将以相反的方向朝手指或笔移动。我们进行了两个实验来比较ShifTable与无辅助的直接选择（基线），手势选择和平移。结果表明，ShifTable在选择时间上明显快于直接选择和手势选择，在错误率上优于手势选择。此外，老年参与者使用ShifTable复制和粘贴目标的速度明显快于Pan。虽然ShifTable的简单操作允许用户轻松自然地在大显示器上选择远程目标，但我们也发现了需要解决的可用性问题，以便这种直观的技术更广泛地被老年用户接受。
To simplify the selection of remote targets on large displays, a novel technique called ShifTable is presented in this paper. With ShifTable, users move a finger or a pen towards a desired target, and the whole screen carrying the target shifts faster in the opposite direction, towards the finger or pen. We conducted two experiments to compare ShifTable with unaided direct selection (baseline), Gesture Select and Pan. The results show that ShifTable was significantly faster than unaided direct selection and Gesture Select in selection time, and outperformed Gesture Select in error rate. In addition, elderly participants were able to copy-and-paste targets significantly faster with ShifTable than with Pan. Although ShifTable's simple operation allows users to easily and naturally select remote targets on a large display, we also found usability issues that need to be addressed for this intuitive technique to be more widely accepted by the elderly users.
