论文摘要
先前的HCI研究经常为可用性和用户体验研究目的分析智能手机应用程序使用数据。应用程序使用视频通常是通过屏幕录制应用程序收集的，以便更好地分析应用程序使用行为（例如，应用程序使用时间，屏幕过渡和通知处理）。但是，很难分析应用程序使用视频以及多个用户交互流数据。当视频的长度很长时，由于用户交互数据的数量，数据分析往往需要很长时间。由于缺乏数据分析经验，对于新手研究人员来说，这甚至更加困难。在本文中，我们提出了LV链链接器（日志和视频链接器），这是一种可视化工具，可通过将多个时间序列日志数据与视频数据链接到APP使用日志和视频数据来迅速探索应用程序使用日志和视频数据。我们对八名参与者进行了初步的用户研究，以通过衡量任务完成时间，帮助和主观任务工作量来评估链接的好处。我们的结果表明，提供链接功能大大降低了任务完成时间和任务工作量。
Prior HCI studies often analyzed smartphone app usage data for usability and user experience research purposes. App usage videos are often collected by a screen recording app in order to better analyze the app usage behaviors (e.g., app usage time, screen transition, and notification handling). However, it is difficult to analyze app usage videos along with multiple user interaction stream data. When the length of a video is long, data analysis tends to take a long time due to the volume of user interaction data. This is even more difficult for novice researchers due to a lack of data analysis experience. In this paper, we propose LV-Linker (Log and Video Linker), a visualization tool that helps researchers quickly explore the app usage log and video data by linking multiple time series log data with the video data. We conducted a preliminary user study with eight participants to evaluate the benefits of linking, by measuring task completion time, helpfulness, and subjective task workload. Our results showed that offering a linking feature significantly lowers the task completion time and task workload.
