Ultrasonic Blind Walking Stick Using Voice Control through Mobile App.

Abstract

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. To overcome all these problems of blind people, we are developing a project by using simple available technologies. This walking stick for blind people has multiple sensors, with the help of which it has been 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 and tell the user which direction to go. The other sensor placed near bottom tip of the walking cane to find the pits on the ground and water sensor to detect the presence of water. We integrate these sensors to the voice record and play chip. In this project, sensors play a key role to detect the objects in all directions and thus help blind people to be independent.
