Microcontroller Based Smart Touch Gadget Assistant for Visually Impaired

Abstract

All over the world, persons who are not able to visualize (blind) have used Braille as the primary
means of accessing information. Almost all countries have adapted the system ‘Braille’ as a universal approach that
works to get the information for visually impaired. This paper describes the hardware implementation of a text to
English Braille translator using Arduino UNO.
Visually impaired people report numerous difficulties with accessing printed text using existing technology,
including problems with alignment, focus, accuracy, mobility and efficiency. We present a device that assists the
visually impaired with effectively and efficiently reading paper-printed text. We introduce a novel, local sequential
manner for scanning text which enables reading single lines, blocks of text. The design is motivated by preliminary
studies with visually impaired people, and it is small-scale and has mobility.
