本文提出了针对视障人士的移动识别系统原型。它的目的是帮助他们使用嵌入式系统和最新技术在现有的手杖上乘坐公共汽车出行。该原型提供了障碍物模块，可在他四处移动时检测障碍物，还提供公交车站标识符以提醒公交车相对于公交车站的位置，以及公交车号码识别以确定公交车路线。该原型将盲文阅读替换为文本转语音模块，使视障人士能够更加独立地独自旅行。嵌入式系统分别采用超声波距离传感器、全球定位系统(GPS)技术和收发器来构建这三个模块。该项目背后的想法是构建一个系统，当盲人导航步行路径和乘坐公共汽车时，通过在手杖上嵌入相关传感设备来提高盲人的行动能力。
This paper presents a prototype of the mobility recognition system for visually impaired people. It is meant to assist them to travel by bus using embedded system and recent technologies to the existing walking cane. The prototype provides obstruction module, detecting obstacles as he moves around, bus stop identifier to alert the bus location with respect to bus stop and bus number identification to determine the bus route. The prototype replaces Braille reading to text-to-speech module giving more independence to the visually impaired person to travel on his own. The embedded system used ultrasound distance sensor, global positioning system (GPS) technology and transceiver in constructing the three modules respectively. The idea behind this project was to construct a system that increases the mobility of the blind people by offering relevant sensing device embedded to walking cane when they navigate their walking path and travelling by bus.
