In this work, we apply an activity theory lens to analyze nonvisual computing for blind and low-vision computer users. Our analysis indicates major challenges for users in translating the activities they are working towards into specific tasks to be completed in a system comprehensible manner. Specifically, blind and low-vision students learning to use accessible technologies struggled with organizing their activities, tracking the history and status of their operations, and understanding how the system was acting underneath these interactions. We discuss how activity-centered design can be applied to nonvisual interfaces to better match user behavior in a computational system.

以活动为中心的非视觉计算机交互方法

在这项工作中，我们应用活动理论镜头来分析盲人和低视力计算机用户的非视觉计算。我们的分析表明，用户在将他们正在努力的活动转化为以系统可理解的方式完成的特定任务方面面临的主要挑战。具体来说，学习使用无障碍技术的盲人和低视力学生在组织活动、跟踪其操作的历史和状态以及了解系统在这些交互下如何运作方面遇到了困难。我们讨论了以活动为中心的设计如何应用于非视觉界面，以更好地匹配计算系统中的用户行为。
