Abstract

Abstract: With almost 3.75 million people with visually impaired in Indonesia, according to statistical data shown that most of them not live in prosperity. To increase their productivity they need an assistive device that's allows them to navigate freely. This paper presents a novel Audio guidance system for blind in the shape of simple bag with earphone for giving them an audio guidance efficiently and safety. Different with other audio guidance, we propose a simple system consist of Raspberry Pi Camera and Ultrasonic Sensor as input, Raspberry Pi, Earphone and Power bank. This system is initiated by providing a voice command of the direction where the blind person must walk or go through, so they can avoid from obstacles. We also apply Fuzzy Logic Controller (FLC) to detect the obstacles along they walk by using 3 ultrasonic sensors. The experimental result shows that by using FLC and interfacing by Raspberry Pi the proposed system can effectively to detect the obstacles and give direction with 2.32% distance error.
