Authors: , , ,
Abstract: The majority of blind or visually impaired students in the third world countries are still using the mechanical brailler for their education. With technology advancements and electronic communication, relying on paper-based brailler would not be efficient nor productive. The "LCE Brailler" is a low-cost electronic brailler whose main features are to vocalize, braille, save and convert Braille characters typed by a blind student to alphabetical ones, which are then displayed on a computer’s monitor. In order to promote an interactive educational experience among students, teachers and parents, the proposed brailler has an affordable low price with advanced capabilities. The device’s design is simplistic and its keyboard is familiar to the blind user. It is based on the raspberry pi technology. The LCE device was tested by visually impaired students and proved to provide accurate mechanical functionality, accuracy, braille-to-text and text-to-audio blind assistant with a user-friendly graphical user interface.
