SMART SHOE FOR VISUALLY IMAPAIRED

Abstract

Mobility is one of the biggest challenges that is faced by person that has lost the gift of sight. The lack of visual prowess results in continuous accidents which in turn cause frequent injuries and limited lifestyle. In order to help these strata of people this project proposes development of smart shoe that would make use of ultrasonic sensor and haptic feedback to timely alert the user. We are thinking of fabricating a smart shoe made up of typical rubber that is found in shoe sole this ensures that project is economical and implementable. Ultrasonic distance sensors (AJ-SR04 Waterproof Ultrasonic Distance Sensor) are to be inculcated into the shoe and the time it would take for transducer to receive radiation would be used to measure distance and alert user. This information would be used by Arduino nano, which is our main processing unit and would compare it with a predefined threshold. When the object crosses the threshold signal from nano would cause motor to vibrate, providing user with haptic feedback. The electronics are to be powered by lithium phosphate battery or cell which would in turn be charged by TP 4056 charging module this ensures long term use. This system hence aims to reduce collision and accidents and be practical in terms of long-term wearability
