iShoes for blind and visually impaired people

This paper presents the development of an iShoes system for blind and visually impaired people. The iShoes system utilizes a microcontroller with sound output interfaced with ultrasonic sensors. The prototype system is designed to be specifically mounted on/in the shoes to aid navigation in urban routes. The ultrasonic transducers determine the range from an obstacle and then play an audio message to reflect the distance from the target. This system will assist blind and visually impaired people in navigating a path through an unfamiliar environment.
