The Blindness is frequently used to describe severe visual impairments with or without residual vision. The application of ultrasonic ranging scheme for producing electronic walking stick for the blind is a technological advancement. There is a great dependency for any type of movement or walking within area or out of the particular area, they use only their natural senses such as touch or sound for identification or walking .To overcome all these problems of blind people, need to develop a project by using simple available technologies. This walking stick for blind people which have multiple sensors, with the help of sensors it has possible to enhance more features to the walking stick. The features are to detect the obstacle for collision avoidance, it detects the object in directions up, down and front. The other sensor placed near bottom tip of the walking cane to find the pits on the ground. Integrate these sensors to the voice record and play chip. Voice record in the different tracks; respond for different sensors to give the audio message to the blind person by the speaker to alert. In this project, sensors plays key role to detect the objects in all directions to make free to walk for the blind people. A dedicated switch is to get the position of the device and send it others through global system for mobile communication (GSM).
