Abstract

Visually impaired people are not sensitive to the input and output units available in communication devices such as smartphones, tablets, etc., and they are forced to use different communication interfaces as an intermediate medium to maintain their daily electronic messaging services. Thus, the use of intermediate media creates a risk regarding the safety and communication efficiency of their data, and the purpose of this research is to carry out preliminary studies on a communication device with touch-sensitive input and output that does not use intermediate media to maintain the communication activities of visually impaired people safely. The primary purpose of this research is to study the use of micromachined refreshable braille display and braille keyboard together to maintain electronic messaging services more securely. The validity of the initial hypothesis related to the above problem was scientifically verified by studying several research papers. Based on the qualitative data collected, a comprehensive study was conducted regarding the weaknesses of the current communication interfaces and the technical solutions that should be provided. Using the data and information gathered from the research, it was possible to present a technical design for a touch-sensitive communication device, and the technical accuracy of the relevant device was confirmed through an expert in the field. The functions and model of a mobile touch-sensitive input and output communication device to carry out electronic messaging communication activities for visually impaired people have been presented here. The device is designed using Braille Grade 1 and a fingerprint sensor is installed in the device to provide security to electronic messaging and related data using bio-matrix authentication technology. There is also a braille keyboard to provide inputs to the system, which is equipped with a micro-machined refreshable braille display that can successfully capture electronic messaging and related outputs for visually impaired people. The above-mentioned braille keyboard of this communication device, designed as a mobile device, is made in slidable form. This communication device will be created to send messages to receive messages as well as to read email and SMS messages. Through this communication device, touch sensitive input and output units including micro-machined refreshable braille display for electronic messaging are designed for the study of use in a communication system, so many functionalities related to electronic messaging have been neglected. That is, here the attention is focused only on sending reply to messages to the received messages as well as reading the email and SMS messages.
