Wheeler: A Three-Wheeled Input Device for Usable, Efficient, and Versatile Non-Visual Interaction
AI总结：
本文提出名为Wheeler的三轮固定式输入设备，通过三个轮子独立导航应用层级并支持2D光标操作，使盲人用户导航时间相比键盘减少40%，并促进混合能力协作。
摘要：
盲人用户依赖键盘和屏幕阅读器等辅助技术与用户界面（UI）元素进行交互。在现代应用中，由于UI层级复杂，导航至不同的UI元素构成了重大的无障碍挑战。用户必须听取屏幕阅读器的音频描述，并逐一按下相关的键盘按键。本文引入了Wheeler，一种新颖的、呈鼠标形状的三轮固定式输入设备，以解决该问题。在参与式设计会议的启发下，Wheeler使盲人用户能够使用三个轮子独立地在应用中导航多达三个层级，而无需像使用键盘那样一次仅导航一个层级。这三个轮子还提供了多功能性，允许用户将其重新用于其他任务，例如2D光标操作。一项有12名盲人用户参与的研究表明，与使用键盘相比，导航时间显著减少了40%。此外，与我们的盲人合著者进行的日记研究突显了Wheeler的额外益处，例如访问具有部分元数据的UI元素以及促进混合能力协作。
英文摘要：
Blind users rely on keyboards and assistive technologies like screen readers to interact with user interface (UI) elements. In modern applications with complex UI hierarchies, navigating to different UI elements poses a significant accessibility challenge. Users must listen to screen reader audio descriptions and press relevant keyboard keys one at a time. This paper introduces Wheeler, a novel three-wheeled, mouse-shaped stationary input device, to address this issue. Informed by participatory sessions, Wheeler enables blind users to navigate up to three hierarchical levels in an app independently using three wheels instead of navigating just one level at a time using a keyboard. The three wheels also offer versatility, allowing users to repurpose them for other tasks, such as 2D cursor manipulation. A study with 12 blind users indicates a significant reduction (40%) in navigation time compared to using a keyboard. Further, a diary study with our blind co-author highlights Wheeler's additional benefits, such as accessing UI elements with partial metadata and facilitating mixed-ability collaboration.
