With over 280 million visually impaired people worldwide, there is a crucial need for an assistive device that allows the blind people to navigate freely. Location information for indoor environment is limited. Radio Frequency Identification (RFID) tags is an effective way of giving location information to the users. We propose a RFID based system for independent navigation in a building for blind or visually impaired people. The conversion of speech to text is carried out using speech recognition software modules. This system is initiated by providing a voice command, and specifying the destination to be reached by the blind person. This navigation system will guide the blind person along the path by providing audio navigation assistance to reach the desired destination. To avoid collision ultrasonic sensor will be interfaced with the Raspberry Pi. By implementing the above technique, blind people can navigate independently and they can acquire information about their current location within the intended building.
