尽管手持式触摸屏设备越来越受欢迎，但关于如何评估和设计单手拇指点击交互的研究却很少。在本文中，我们提出了一项研究，研究了与这些交互相关的三个问题：1）是否有必要评估与首选手和非首选手的这些交互； 2）评估这些互动的参与者是否应该被要求在评估过程中站立和行走； 3）屏幕边缘的目标是否比不在边缘的目标能让参与者更准确地选择。研究中的四十名参与者中有一半使用了他们不喜欢的手，一半使用了他们喜欢的手。每个参与者一半的任务是在步行时完成的，一半是在站立时完成的。我们使用了 25 个不同的目标位置（16 个位于屏幕边缘）和五种不同的目标尺寸。使用自己喜欢的手的参与者比使用不喜欢的手的参与者更快、更准确地完成任务，差异足够大，表明有必要评估这种类型的双手交互。我们没有发现参与者行走时和站立时的表现存在差异，这表明没有必要将其作为评估中的变量。在目标位置方面，参与者认为屏幕中心附近的目标点击起来更容易、更舒适，但准确率最高的是屏幕边缘的目标。
In spite of the increasing popularity of handheld touchscreen devices, little research has been conducted on how to evaluate and design one handed thumb tapping interactions. In this paper, we present a study that researched three issues related to these interactions: 1) whether it is necessary to evaluate these interactions with the preferred and the non-preferred hand; 2) whether participants evaluating these interactions should be asked to stand and walk during evaluations; 3) whether targets on the edge of the screen enable participants to be more accurate in selection than targets not on the edge. Half of the forty participants in the study used their non-preferred hand and half used their preferred hand. Each participant conducted half of the tasks while walking and half while standing. We used 25 different target positions (16 on the edge of the screen) and five different target sizes. The participants who used their preferred hand completed tasks more quickly and accurately than the participants who used their non-preferred hand, with the differences being large enough to suggest it is necessary to evaluate this type of interactions with both hands. We did not find differences in the performance of participants when they walked versus when they stood, suggesting it is not necessary to include this as a variable in evaluations. In terms of target location, participants rated targets near the center of the screen as easier and more comfortable to tap, but the highest accuracy rates were for targets on the edge of the screen.
