在本文中，我们提出了一种可穿戴的智能系统，帮助视障人士在街道上独自行走，在公共场所导航，并寻求帮助。该系统的主要组成部分是微控制器板、各种传感器、蜂窝通信和GPS模块以及太阳能电池板。该系统采用了一组传感器来跟踪路径，并提醒用户前方有障碍物。用户通过蜂鸣器发出的声音和手腕上的振动来提醒用户，这在用户听力损失或处于嘈杂环境中时很有帮助。此外，当用户跌倒或需要帮助时，系统会提醒周围的人，警报与系统位置一起，作为电话消息发送给家庭成员和照顾者的注册手机。此外，注册的电话可以在需要时用于检索系统位置，并激活对VIP的实时跟踪。对系统原型进行了测试，验证了系统的功能和有效性。与其他同类系统相比，该系统具有更多的特点。我们希望它能成为提高贵宾生活质量的有用工具。
In this paper, we present a wearable smart system to help visually impaired persons (VIPs) walk by themselves through the streets, navigate in public places, and seek assistance. The main components of the system are a microcontroller board, various sensors, cellular communication and GPS modules, and a solar panel. The system employs a set of sensors to track the path and alert the user of obstacles in front of them. The user is alerted by a sound emitted through a buzzer and by vibrations on the wrist, which is helpful when the user has hearing loss or is in a noisy environment. In addition, the system alerts people in the surroundings when the user stumbles over or requires assistance, and the alert, along with the system location, is sent as a phone message to registered mobile phones of family members and caregivers. In addition, the registered phones can be used to retrieve the system location whenever required and activate real-time tracking of the VIP. We tested the system prototype and verified its functionality and effectiveness. The proposed system has more features than other similar systems. We expect it to be a useful tool to improve the quality of life of VIPs.
