Proposed system provide detection and classification of obstacle in real time, used to aid visually
impaired people to provide safety within indoor and outdoor environment, by using Smartphone device. When a
blind person walking in an unfamiliar area, they faces so many problems like they does not identify true obstacles,
potholes, bumps, etc in his way. To avoid these problems, there are various ETA tools are available in market for
helping visually impaired people. But most of visually impaired people are not affordable these kind of ETA tools.
And also they does not provide complete information about the environment in which the user is present. So this
paper describes a real-time system which makes use of the ultrasonic sensor and Smartphone for detection of
obstacles that helps to find the path of visually impaired peoples. In which the ultrasonic sensor detects the
measure of distance of obstacles in front of the user. The output is given to the user in the form of audio or
vibration on the mobile.
