一路去又回：面向盲人旅行者的基于惯性、手机放口袋的室内寻路与回溯应用
All the Way There and Back: Inertial-Based, Phone-in-Pocket Indoor Wayfinding and Backtracking Apps for Blind Travelers
AI总结：
本文提出两款仅依赖手机惯性传感器、无需基础设施改造的iOS应用，分别支持盲人在室内基于楼层平面图寻路和无地图回溯，并通过智能手表与语音交互，在七名盲人参与的校园建筑导航测试中得到验证。
摘要：
我们介绍了两款iOS应用，旨在支持盲人旅行者在室内建筑环境中进行寻路和回溯。寻路涉及确定并沿建筑走廊中的路线行进以到达目的地，并假设应用能够获取该建筑的楼层平面图。另一方面，回溯自己的路线不需要任何地图知识。我们的应用仅使用智能手机的惯性和磁力传感器，因此不需要对基础设施进行任何改造（例如安装和支持BLE信标）。与使用手机摄像头的系统不同，我们应用的用户可以方便地将手机放在口袋里，同时通过智能手表与应用进行交互。路线指引通过语音给出。这两款应用在一项用户研究中进行了测试，参与者为七名盲人，他们在校园建筑中导航时使用了这些应用。
英文摘要：
We introduce two iOS apps that have been designed to support wayfinding and backtracking for blind travelers navigating in indoor building environments. Wayfinding involves determining and following a route through the building's corridors to reach a destination, and assumes that the app has access to the floor plan of the building. Backtracking one's route, on the other hand, requires no map knowledge. Our apps only use the inertial and magnetic sensors of the smartphone, and thus require no infrastructure modification (e.g., installation and support of BLE beacons). Unlike systems that use the phone's camera, users of our apps can conveniently keep their phone tucked inside a pocket, while interacting with the apps using a smartwatch. Routing directions are given via speech. Both apps were tested in a user study with seven blind participants, who used them while navigating a campus building.
