This paper represents is an investigation of the development of navigation aid for blind and visually impaired people. It based on a microcontroller AVR Atmega328 with having synthetic speech output. This project is built to use the blind as well as they may walk easily in rural areas as well as avoid obstacles using special detection sensors. The paper shows an innovative project design and implementation of Ultrasonic sensors fitted with the system provides obstacle data to the blind person through voice message so that he/she may avoid them. As well as, to reduce the navigation difficulties of the blind, and obstacle detection system using ultrasounds and vibrators is added to this device. The proposed system detects the nearest obstacle via an ultrasonic sensor and sends back vibrator tactile feedback to inform the blind about its location. In this project, the system is designed in such a way that it gathers data about the environment via ultrasonic sensors and extracts the visual information that data. The information is to transform the audio signal and the blind person can recognize the environmental information through binaural sound generated by the system.
