The students of Sir Syed University of Engineering and Technology (SSUET) have developed a Braille system that works on the basis of micro-controller. The micro-controller-based Braille system is a tactile communication mode that uses the mobile and other mechanical devices to enable visually handicapped children or adults to read from a portable device.
The system developers claimed that current cell technology was expensive but their project researched less costly alternatives resulting in the development of own cell using solenoids.
They said the main concern for their project was how a blind person read SMS from his mobile and for this purpose, they had designed a Braille Pad in which eight Braille Cells had been connected in parallel on which a blind can read words one by one with a button given for next and previous word.
