In existing system to guide the visually impaired people they need neighbors help for navigation and guidance. In proposed system, LED is deployed in buildings. In this method, colored LEDs are used to help the image sensor to distinguish between different light sources. Zigbee technology can be combined with VLC to realize long distance positioning. MODIFICATION PROCESS, The blind person module consists of a mobile connected through LiFi, a vibrator, and an ultrasonic sensor. Ultrasonic sensor… Expand
