Smart Shopping Assistant for Visually Impaired Persons using Raspberry Pi

Abstract

There are all-around more than 315 million people who are visually impaired in the world and the number is increasing as the generation ages. Here the work is carried to make the life of visually impaired/ blind people easy and independent. A camera-based gadget is used here which scans any type of Barcode and QR_code behind the commodity and read the detailed description of the commodity with the help of ID or unique number saved in the codes using the raspberry pi 4 microcontroller. It is very difficult for the visually impaired/ blind people to get the details of the packaged goods to compare. The device/gadget proposed here will be very beneficial for these people in this regard and hence will help them in taking the decisions of either purchasing a commodity or not. The proposed offline smart gadget can be used in different places like shops, shopping malls, Book stores and pharmacy stores, etc. This has been tested that through the device proposed in the research work, people are able to identify labeled and unlabelled commodities of their daily life use.
