支持基于触摸屏的移动的设备的单手拇指操作提出了视觉表现力和交互简易性之间的具有挑战性的折衷。ThumbSpace和Shift--两种新的独立于应用程序的、基于软件的交互技术--以截然不同的方式解决了这一问题。ThumbSpace解决远距离对象，而Shift解决小对象遮挡。我们提出了两个广泛的，比较用户研究。第一个将ThumbSpace和Shift与外围硬件（方向垫和滚轮）和站立和行走时选择对象的直接触摸屏输入进行比较。数据总体上支持Shift设计，但表明ThumbSpace对遥远的物体很有希望。我们的第二项研究探讨了在具有更大屏幕（3.5”）的设备上结合Shift和ThumbSpace的好处和可学习性。我们发现，它们的结合使用为用户提供了更好的整体速度和准确性，在击中小目标（3.6平方毫米）比单独使用任何一种方法。
Supporting one-handed thumb operation of touchscreen-based mobile devices presents a challenging tradeoff between visual expressivity and ease of interaction. ThumbSpace and Shift---two new application-independent, software-based interaction techniques---address this tradeoff in significantly different ways. ThumbSpace addresses distant objects while Shift addresses small object occlusion. We present two extensive, comparative user studies. The first compares ThumbSpace and Shift to peripheral hardware (directional pad and scrollwheel) and direct touchscreen input for selecting objects while standing and walking. The data favored the Shift design overall, but suggested ThumbSpace is promising for distant objects. Our second study examines the benefits and learnability of combining Shift and ThumbSpace on a device with a larger screen (3.5"). We found their combined use offered users better overall speed and accuracy in hitting small targets (3.6 mm2) than using either method alone.
