Abstract In recent years, the use of touchscreen mobile devices in a variety of places and contexts has been raised. Specific interaction context induced impairment and disabilities that can limit the usage of these devices. For instance, the use of a mobile device while walking in sunlight limits the visual attention and results in performance reduction. In this paper, we present a study that investigates distinctions between the made gestures by individuals in two different situations: while walking in sunlight glare and sitting at a table without visibility impairment. The results show that (1) the individuals tend to draw larger and broader gestures in situational impairment, (2) the variation in the time and speed depended on the user familiarity with the gestures, and (3) there wasn't great different behavior in how to apply strokes.

情境障碍对公共场所触摸手势的影响：在阳光下行走

摘要 近年来，触摸屏移动设备在各种场所和环境中的使用有所增加。特定的交互环境导致的损伤和残疾可能会限制这些设备的使用。例如，在阳光下行走时使用移动设备会限制视觉注意力并导致性能下降。在本文中，我们提出了一项研究，该研究调查了个人在两种不同情况下做出的手势之间的区别：在阳光下行走时和坐在桌子旁而没有可见度障碍。结果表明：（1）个体在情境障碍中倾向于绘制更大更宽的手势，（2）时间和速度的变化取决于用户对手势的熟悉程度，以及（3）没有很大的不同行为在如何应用笔画。
