Netra: An RFID-Based Android Application for Visually Impaired

In India, almost 18 million visually impaired people have difficulties in managing their day-to-day activities. Hence, there is a need to develop an application that can assist them every time and give vocal instructions in both English and Hindi. In this paper, we introduced a robust lightweight Android application that facilitates visually impaired individuals by providing a variety of essential features such as object and distance detection, Indian currency note detection, and optical character recognition that can enhance their quality of life. This application aims to have a user-friendly GUI well suited to the needs of the blind user and modules like Object Recognition with Image Captioning so that the visually challenged user can gain a better understanding of their surroundings.

This paper introduces a reliable and user-friendly Android application that helps visually impaired users recognize U.S banknotes. The application relies only on an Android Smartphone and does not require any wireless data connection or back-end infrastructure. The application is proven to be robust and reliable under various environmental conditions which differ in lighting and background conditions. The overall banknote detection accuracy is over 94% in any lighting conditions (even in a dark room) or backgrounds with near real-time banknote detection time of 7 seconds. The main contribution of this paper is the use of a robust and reliable computer vision algorithm on the Android platform combined with a friendly “vision free” user interface.

Learning Methods

Braille codes are letters that are known by blind people to be able to obtain information through books including the Qur'an. The availability of media to learn to read the Qur'an in Braille code for blind people is very limited. In addition, the availability of teachers of the Koran for the blind is very limited because not many people can see normally who understands the Qur'anic letters in Braille code, so it is necessary to design and implement an Iqra Electronic Braille device to facilitate the reading process. the Qur'an in Braille code for blind people. One of the Koran learning methods applied in this design is the Iqra method. This device consists of two parts, namely a device for teachers / instructors in the form of an android application and a device for students / blind people who will learn in the form of electronic devices Braille cell viewers using piezoelectric mechanics. Communication between the Teacher's device and the Student's device uses wireless communication media, namely Bluetooth. The Iqra electronic device for the visually impaired is expected to facilitate teachers to teach blind people to read the Qur'an in the Braille code using the Iqra method as an effort to reduce the illiteracy of the Qur'an, especially blind people.
