我们进行了几个实验，使用个人数字助理（PDA）作为输入设备的非优势手沿着与鼠标的优势手。PDA是一种小型手持掌上电脑，如3Com Palm Pilot或Windows CE设备。这些都变得广泛可用，并很容易连接到PC。我们的实验结果表明，人们可以准确，快速地选择在PDA上的按钮中使用的左手不看的小数目，而且，正如预测的那样，性能下降按钮的数量增加。在键盘和设备之间移动双手的归巢时间仅比单手移动鼠标的时间慢10%至15%，这表明获得两个设备不会造成很大的损失。在一项应用任务中，我们发现使用PDA上的按钮或滚动条滚动网页的速度与使用鼠标和传统滚动条的速度相匹配，并且击败了早期实验中报道的最佳双手时间。这些结果将有助于使双手与计算机的互动更广泛，更有效。
We performed several experiments using a Personal Digital Assistant (PDA) as an input device in the non-dominant hand along with a mouse in the dominant hand. A PDA is a small hand-held palm-size computer like a 3Com Palm Pilot or a Windows CE device. These are becoming widely available and are easily connected to a PC. Results of our experiments indicate that people can accurately and quickly select among a small numbers of buttons on the PDA using the left hand without looking, and that, as predicted, performance does decrease as the number of buttons increases. Homing times to move both hands between the keyboard and devices are only about 10% to 15% slower than times to move a single hand to the mouse, suggesting that acquiring two devices does not cause a large penalty. In an application task, we found that scrolling web pages using buttons or a scroller on the PDA matched the speed of using a mouse with a conventional scroll bar, and beat the best two-handed times reported in an earlier experiment. These results will help make two-handed interactions with computers more widely available and more effective.
