This study aims to investigate the effects of edge displays on smartphone usage in one-hand-only use scenarios and identify issues related to touch errors. Experiments were conducted by recreating typical usage environments to mimic the use of phones in cafeterias, homes, and mobile settings. A framework to analyze smartphone usage and human errors was developed. We collected data on the usage errors and use cases through a head-mounted camera donned by participants and a screen-recording application. The results showed that the number of incidents involving unintentional touching of screen edges for edge-screen smartphones is five times higher than that for typical flat smartphones. Moreover, the lying down position is more susceptible to errors for both types of smartphones. These results indicate the necessity of design strategies to reduce unrelated touching of screen edges and the importance of considering various body postures to elucidate a better understanding of smartphone usage.

这项研究旨在调查边缘显示在单手使用情况下对智能手机使用的影响，并确定与触摸错误相关的问题。通过重新创建典型的使用环境以模仿自助餐厅，家庭和移动场所中电话的使用来进行实验。开发了分析智能手机使用情况和人为错误的框架。我们通过参与者佩戴的头戴式摄像头和屏幕录制应用程序收集了有关使用错误和用例的数据。结果表明，边缘屏幕智能手机涉及意外触摸屏幕边缘的事件数量是典型平板智能手机的事件数量的五倍。此外，对于两种类型的智能手机，躺下位置更容易出错。
