PROMINENT NAVIGATION FOR VISUALLY IMPAIRED PEOPLE

The most of the technical challenges for the society to detect and find a solution for visually impaired, with increased security and service motto towards the society helped to bring a solution which would help the visually impaired in the industries and other companies. Here we had come out with a prototype as a way of finding a solution to the visually impaired. The navigation assistant technology using RFID Tag Grid minimizes the dependency. The reader used in this system is embedded in the mobile and shoes to avoid dependency on travel. The RFID reader matches with the information specified to that ID and a voice signal is generated. Wireless RF links is placed in the Bluetooth device/ headphone for voice guidance. The proximity sensing unit is an auxiliary unit is added as a solution to address unexpected and non-mapped obstacles in the user’s path. Basically it contains ultrasonic Sensor Unit interfaced with microcontroller which is inter-linked to a vibrator that would be activated when nearing obstacles. This system is technically and economically feasible and may offer a maximum benefit to the disabled.
