Abstract

Smartphones play a crucial role in daily activities, however, situationally-induced impairments and disabilities (SIIDs) can easily be experienced depending on the context. Previous studies explored the effect of context but mainly done in controlled environments with limited research done in the wild. In this article, we present an in-situ remote user study with 48 participants’ keyboard interaction on smartphones including the performance and context details. We first propose an automated approach for error detection by combining approaches introduced in the literature and with a follow-up study, show that the accuracy of error detection is improved. We then investigate the effect of context on the typing performance based on five dimensions: environment, mobility, social, multitasking, and distraction, and reveal that the context affects participants’ error rate significantly but with individual differences. Our main contribution is providing empirical evidence with an in-situ study showing the effect of context on error rate.
语境对智能手机用户野外打字表现的影响
智能手机在日常活动中发挥着至关重要的作用,然而,根据具体情况,很容易体验到情境诱发的障碍和残疾。先前的研究探讨了环境的影响,但主要在受控环境中进行,在野外进行的研究有限。在本文中,我们对48名参与者在智能手机上的键盘交互进行了现场远程用户研究,包括性能和上下文细节。我们首先提出了一种自动的错误检测方法,将文献中介绍的方法与后续研究相结合,表明错误检测的准确性得到了提高。然后,我们从环境、流动性、社交、多任务处理和分心五个维度研究了上下文对打字表现的影响,并发现上下文对参与者的错误率有显著影响,但存在个体差异。我们的主要贡献是通过现场研究提供经验证据,显示上下文对错误率的影响。

期刊介绍: This ACM Transaction seeks to be the premier archival journal in the multidisciplinary field of human-computer interaction. Since its first issue in March 1994, it has presented work of the highest scientific quality that contributes to the practice in the present and future. The primary emphasis is on results of broad application, but the journal considers original work focused on specific domains, on special requirements, on ethical issues -- the full range of design, development, and use of interactive systems.
