Raspberry Pi and White Cane Integration for Assisting the Visually Impaired

There are at least 2.2 billion people in the world who have near or distant visual impairment according to data from the World Health Organization (WHO).According to the Perkins School for the Blind, only 2% to 8% of blind people use white canes.This is because 90% of them have accidents when using walking sticks.We have created a system to help the visually-impaired upgrading the white cane by implementing four essential elements: An electrical-setup employing a simple computer board (Raspberry Pi), connected to an HC-SR04 ultrasonic distance sensor that measures the distance to an object using ultrasonic sound waves, and voice feedback that alerts the owner of nearby objects via a speaker.Furthermore, a Raspberry Pi Camera for real-time object detection with a deep learning algorithm capability "YOLO" is used.The locations of these elements in the white cane are situated in the blind spots to avoid accidents to the owner.
