Independence is the building's methodology for achieving dreams, goals and objectives in life. People with visual impairments are challenged to leave independently. There are millions of visually impaired or blind people in this world who are always in need of helping hands. For many years the white cane became a well-known attribute to the navigation of blind people and later efforts have been made to improve the cane by adding remote sensor. Blind people have big problems when they walk down the street or down stairs using white cane, but they have a sharp haptic sensitivity. The electronic baton will aid the blind person by providing more convenient livelihoods. The main objective of this work is to contribute with our knowledge and services to blind people and to disable society.
Blind stick is an innovative stick designed for visually impaired people to improve navigation. Here we propose an advanced blind stick that allows visually challenged people to navigate easily using advanced technology. The blind stick integrates with the ultrasonic sensor along with the light and water it detects. Our proposed project uses ultrasonic sensors first to detect obstacles ahead using ultrasonic waves. Upon detection of obstacles, the sensor passes this data to the microcontroller. The microcontroller then processes these data and calculates whether the obstacle is close enough. If the obstacle is not so close the circuit does nothing. If the obstacle is near, the microcontroller sends a signal to sound a buzzer. It also detects and sounds a different buzzer if it detects water and alerts the blind. One more feature is that it allows the blind to detect whether there is light or darkness in the room. The system has a more advanced feature integrated to help the blind find their stick if they forget where they saved it. For this, a rf-based wireless remote control is used. Pressing the remote button sounds a buzzer on the stick that helps the blind person find his stick. Therefore, this system allows the detection of obstacles as well as finding stick if it was misplaced by visually impaired people.
