iOS和Android引入增强现实技术，首次使主流智能手机能够高精度地估计自己在3D空间中的运动。对于辅助技术研究人员来说，这一发展提供了一个潜在的机会。本着这种精神，我们展示了利用这些技术创建智能手机应用程序的工作，使视障人士能够更轻松地在室内环境中导航。我们的应用程序 Clew 允许用户记录路线，然后随时加载它们，沿路线提供自动引导（使用触觉、语音和声音反馈）。我们展示了以用户为中心的设计流程、Clew 的系统架构和技术细节，以及应用程序的小型和大规模评估。我们讨论了利用增强现实进行定向和移动应用程序的机会、陷阱和设计指南。我们的工作扩展了可大规模分布的定向和移动技术的能力。
The introduction of augmented reality technology to iOS and Android enables, for the first time, mainstream smartphones to estimate their own motion in 3D space with high accuracy. For assistive technology researchers, this development presents a potential opportunity. In this spirit, we present our work leveraging these technologies to create a smartphone app to empower people who are visually impaired to more easily navigate indoor environments. Our app, Clew, allows users to record routes and then load them, at any time, providing automatic guidance (using haptic, speech, and sound feedback) along the route. We present our user-centered design process, Clew's system architecture and technical details, and both small and large-scale evaluations of the app. We discuss opportunities, pitfalls, and design guidelines for utilizing augmented reality for orientation and mobility apps. Our work expands the capabilities of technology for orientation and mobility that can be distributed on a mass scale.
