摘要

本文描述了一种基于rfid的系统,可以帮助视障人士定位和导航物理环境。这种响应式环境系统是通过使用以下两种互补组合开发的:1)嵌入盲文块的射频识别(RFID)技术和2)集成电子同情的无线射频识别阅读器。RFID标签存储盲文模式的信息,并将其提供给读者以声音演示信息。演示的信息有两种类型:1)自动响应危险或障碍物位置的信息;2)当用户按下按钮要求系统识别环境、方向和目的地的物理条件时的信息。结果表明,该系统提高了视障人士的空间感知效率和可达性。用户能够在遇到障碍物之前停止行走,识别步行路径的位置和方向,并正确地到达目的地。

Application of Radio Frequency Identification (RFID) Technology for Environment Improvement to Increase Efficiency of Spatial Perception and Accessibility for the Blinds
This paper describes an RFID-based system that helps localizing and navigating physical environmentsfor the visually impaired person. This responsive environment system was developed by using a complementarycombination of 1) Radio Frequency Identification (RFID) technology embedded in Braille Block and 2) along cane RFID-reader integrated with electronic compassion. The RFID tags store information of a braillepattern and give it to the reader to demonstrate information by sounds. There are 2 types of the informationdemonstrated: 1) the information that is automatically responsive with the location of hazards or obstacles2) the information that responds when the user pushes the button for asking the system to identify a physicalcondition of the environment, direction and destination. The results showed that the system increasedefficiency of spatial perception and accessibility for the visually impaired. The user was able to stop walkingbefore encountering with obstacles, recognize positions and directions of the walk way and access to thedestination correctly.
