RouteNav是一款iOS应用程序，旨在为室内/室外交通枢纽的盲人旅行者提供寻路服务。它不依赖于外部基础设施（如BLE信标）；通过粒子滤波，将惯性航位推算和GPS（在可用的情况下）的空间信息融合得到定位。路径被表示为“贴图”序列，每个贴图可能包含相关的兴趣点。冗余模式用于引导用户在瓷砖内切换门柱。在本文中，我们描述了RouteNav的不同组成部分，并报告了一项由7名盲人参与者参与的用户研究，他们在一个交通枢纽穿越三条具有挑战性的路线，同时接收来自应用程序的输入。
RouteNav is an iOS app designed to support wayfinding for blind travelers in an indoor/outdoor transit hub. It doesn’t rely on external infrastructure (such as BLE beacons); instead, localization is obtained by fusing spatial information from inertial dead reckoning and GPS (when available) via particle filtering. Routes are expressed as sequences of “tiles”, where each tile may contain relevant points of interest. Redundant modalities are used to guide users to switching goalposts within tiles. In this paper, we describe the different components of RouteNav, and report on a user study with seven blind participants, who traversed three challenging routes in a transit hub while receiving input from the app.
