| Summary: | Individuals with a good understanding of
mathematics have better chances to do well in their life.
However, it is an extremely challenging task for people with
visual disabilities to learn and execute simple mathematical
operations. Although there are many mathematical learning
products in the current market, most of them are expensive,
with smooth input keys, liquid crystal display and audio
outputs which limit the learning process of numerical braille
code. In this paper, we present a numerical braille module
which aimed to help people with visual challenges to learn
simple mathematical operations. This module comprises 12
miniature solenoids that were controlled by an Arduino Uno
microcontroller with a numeric keypad that serves as an input
unit. The verification of input and output signals was
conducted to ensure that all the inputs are correctly stored in
Arduino board memory to perform a correct operation and
raised the correct solenoids to produce a braille code pattern.
Three operations were tested, which are addition, subtraction
and multiplication. The developed numerical braille module
was capable of performing simple calculations tasks and raised
correct solenoid output accordingly. The outcome of this work
provides an optimistic prospect of attracting the visually
impaired to learn and perform mathematical operations. |
