This paper describes the method for sustaining a visual impaired people. This helps to detect identifies and avoids objects in the field of vision of the surroundings. This paper specifically runs with ultrasonic sensor. The ultrasonic sensor is used to spot and measure the object distances and distance is measured in the form of feet. An audio representation is recognized as output unit. Then the corresponding audio will be pass on to the blind people via earpiece and guided by describing the objects and object distance to the person in the field of vision.
Finally this device embedded with the fault tolerance system such as GPS and GSM. Global Positioning System which gives the current location of the impaired people. Navigation information sends by means of text message. Global System for Mobile Communication it send message to service man and to family member when the system get fault.
Power distributed to the device by 2 way power supply . One by means of battery and other by solar. This is done to achieve robustness.
