Intelligent Stick For Visually Impaired People

Abstract

The significant developments has been made in field T of rehabilitation in last few decades. Noticeable
improvements can be seen in the commercially available devices for the help of visually impaired people. In spite of the current advance technology, this area still needs highly efficient and smart tools that can help such people in moving smoothly and with freedom. This study proposes the use of an open-source single-board computer Raspberry Pi to assemble a device for visually impaired people. The ultrasonic sensor was successfully interfaced with the Raspberry Pi board and measured the distance from the target or obstacle. The obstacle was detected on
