SUMMER WORKSHOP ON DESIGN AND INCLUSIVE INNOVATION

MOBILE CURRENCY IDENTIFICATION FOR VISUALLY IMPAIRED


Objective
Intended to help the visually impaired to identify the various currency denominations, differentiate them with ease and keep them conveniently for easy access


Introduction
India has a net population of 3.5 million visually impaired people. These people face a lot of difficulty in their monetary transactions. The relative measurement of the length of the currency notes using palms and fingers might lead to an inaccurate judgement. The tactile symbols on the currency notes are obsolete to be used for recognition. An available solution is a mechanical device like scale which has markings for the length of the various denominations of the currency notes. We aim at providing an inclusive solution in the form of an application installed in the user’s mobile. This application would use the camera module to recognise the currency and inform the user with an audio or vibratory output as desired by the user. A smart wallet is also being designed to reduce the need to use the application repeatedly while giving currency. This we believe would empower the visually impaired and instil confidence when they go through monetary transactions.


Proposed Solution

We intend to make an Android application with very simple user interface supported by audio feedback that would help the user to adjust camera; the application would automatically click a picture as soon as it detects all the edges in camera preview. Using image processing (colour detection, size estimation and pattern recognition) and OCR the audio output would be given. The application would include some other utility features like ‘Counting Mode’ to help user know the total sum in his/her hands by detected them one by one using mobile. The smart wallet is an additional support to the users to keep their money in a better organised manner and avoid situations like giving away a currency note of higher denomination due to confusion in storing
