God gifted sense of vision to the human being is an important aspect of our life. But there are some unfortunate people who lack the ability of visualizing things. The visually impaired have to face many challenges in their daily life. The problem gets worse when they travel to an unfamiliar location. The old system are not work properly in outdoor applications. In this paper, we propose a navigation device for the visually impaired which is focused on providing voice output for obstacle prevention and navigation using the ultrasonic sensor, ADXL325 sensor. We also use the GSM/GPS module, voice ic, mike and buzzer. Using this system we alert the blind person’s relatives.
