摘要

在辅助技术领域,大规模用户研究受到潜在参与者地理稀疏和纵向研究往往耗时这一事实的阻碍。在这项贡献中,我们依靠远程使用数据对iMove的用户进行大规模和长时间的行为分析,iMove是一款支持视力障碍人士定向的移动应用程序。探索性分析突出了iMove用户中流行的功能、常用配置设置和使用模式。该研究显示,通过VoiceOver访问该应用程序的用户与其他用户之间存在明显差异,后者往往更少、更偶尔地使用该应用程序。通过对VoiceOver iMove用户交互的聚类分析,我们发现了四个不同的用户群体:1)对周边兴趣点感兴趣的用户,2)在移动过程中长时间保持应用活跃的用户,3)短时间互动查询当前位置的用户,4)短时间查询周边兴趣点和地址的用户。我们的分析提供了对iMove用户基础的洞察,可以为针对不同用户群体定制应用程序、开发软件的未来改进或指导类似辅助工具的设计过程提供决策依据。

Supporting Orientation of People with Visual Impairment: Analysis of Large Scale Usage Data
In the field of assistive technology, large scale user studies are hindered by the fact that potential participants are geographically sparse and longitudinal studies are often time consuming. In this contribution, we rely on remote usage data to perform large scale and long duration behavior analysis on users of iMove, a mobile app that supports the orientation of people with visual impairments. Exploratory analysis highlights popular functions, common configuration settings, and usage patterns among iMove users. The study shows stark differences between users accessing the app through VoiceOver and other users, who tend to use the app more scarcely and sporadically.Analysis through clustering of VoiceOver iMove user interactions discovers four distinct user groups: 1) users interested in surrounding points of interest, 2) users keeping the app active for long sessions while in movement, 3) users interacting in short bursts to inquire about current location, and 4) users querying in bursts about surrounding points of interest and addresses. Our analysis provides insights into iMove's user base and can inform decisions for tailoring the app to diverse user groups, developing future improvements of the software, or guiding the design process of similar assistive tools.
