ABSTRACT

Intelligent guidance in complex environments where various procedures are required for navigation is critical to achieving mobility for the visually impaired. This study presents a newly developed software prototype with a hybrid RFID/BLE infrastructure to provide intelligent navigation and guidance to the visually impaired in complex indoor environments. The system enables the users to input their purpose via a specially designed user interface, and provides intelligent guidance through a chain of destination targets which are determined according to the inherent procedures of the environment. Path optimization is performed by adaptation of the traveling salesman problem, and real-time instantaneous instructions are provided to guide the users through the predetermined destination points. For evaluation purposes, a hospital environment is constructed as an example of a complex environment and the system is tested by visually impaired participants. The results show that the intelligent purpose selection and destination evaluation mechanism modules of the system are found to be effective by all the participants.

面向视障人士的智能室内导引导航系统

摘要

在需要各种导航程序的复杂环境中进行智能引导对于实现视障人士的机动性至关重要。本研究展示了一种新开发的软件原型,该原型具有混合 RFID/BLE 基础设施,可为复杂室内环境中的视障者提供智能导航和引导。该系统使用户能够通过专门设计的用户界面输入他们的目的,并通过根据环境固有程序确定的一系列目的地目标提供智能指导。通过适应旅行商问题进行路径优化,并提供实时瞬时指令以引导用户通过预定目的地点。出于评估目的,一个医院环境被构建为一个复杂环境的例子,并且该系统由视障参与者进行测试。结果表明,系统的智能目的选择和目的地评价机制模块被所有参与者认为是有效的。
