The visually impaired have to face many challenges in their daily life. The problem gets worse when there is an obstacle in front of them. They feel difficulties Blind stick is an innovative stick designed for visually disabled people for improved navigation. To overcome all these problems of blind people, we are developing a walking cane with OPCFD system by using simple available technologies. OPCFD system which means it can detect obstacles, pits, ceilings and fire .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 up, down and front. The other sensor placed near bottom tip of the walking cane to find the pits on the ground. Temperature sensor to detect temperature of the surroundings and wheel with generator connected to end of the walking cane while walking due to the rotation of the wheel it produce some current.In this project, sensors play a key role to detect the objects in all directions and thus help blind people to be independent.
