The main aim of this work is to help blind people by providing a smart stick to them. We know that blind people find a lot of difficulties in distinguishing obstacles while walking on the road. This work will provide safe communication and object recognizing for blind people by making use of Raspberry Pi. The mission of this work is to provide a voice based assistance to blind people. This system consists of ultrasonic sensors, Raspberry Pi, speaker, etc. This stick discovers an object around them and sends acknowledgement in the form of speech, danger alerts through audio by speaker for blind people. In ordinary stick, the obstacle detection is not performed and ordinary stick is not efficient for blind persons. Because the visually impaired person does not know what kind of obstacles or what type of things might come in front of him/her. It provides a low price and effective navigation and object detection assistance for blind people which provides a sense of artificial vision by giving information about the environment, things on all sides of them, so they can walk on one's own without any risk and difficulties. If any obstruction occurs in front of blind person, he/she can hear the sound produced by the speaker and can know about the obstacle or things. This stick is very useful for people who are blind and are frequently need help from others.
