Comprehensive Analysis of Indian Currency Recognition System and Location Tracking for Visually Impaired

Abstract

According to a survey, approximately 5.4 million people face the problem of visual impairment in the country. Blind people face problems when moving from one place to another many of them use a white cane or stick or a working dog for assistance. When they travel from one place to another, their loved ones are worried about their location. Caretakers or their loved ones find it hard to trace the real-time location of the blind person. Moreover, blind folks face difficulties in contacting their loved ones in case of emergency. They even find it hard to recognize the currencies. Despite the advantages of technology and the enormous usage of electronic cards and e-payments, banknotes are still primarily used owing to its ease. There are about 11 different Indian currencies, and each banknote is distinct from others in various aspects like colour and dimensions. Blind folks find it hard to use the cards and other electronic payments, so they find it hard in recognizing the currencies. Currency Recognition System (CRS) could be useful in identifying currency for visually impaired persons. In the proposed system, the Android-based solution to aid the loved ones to track the real-time location of the blind folks with a smart calling facility and a Currency Recognition System based on Teachable Machine with Google design to recognize various currencies. In Teachable Machine, models are trained using the technique called transfer learning. It aims to provide fast and accurate results for the given image. The goal of this proposed scheme is to make life easier for a visually impaired person.
