A group of third year engineering students studying at Cummins College
of Engineering for Women at the city of Pune, India has developed a
Braille keyboard with a speech
feedback that will make typing easy for the visually impaired. the
device will help visually impaired students to write their examination
papers on their own, without the assistance of another person.
"This keyboard has six keys out of which there are three special keys.
Any blind person can easily use these six keys. There are three
special keys
called done, space and delete. Once a blind person finishes typing an
alphabet, he can press done and if he feels he has to delete what he
has typed,
he can press delete. The keyboard has been designed exactly like the
Braille language matrix with three additional
keys. The device consists of a Braille keyboard connected to a micro
controller and a text to speech (TTS) converter, which gives output as
sound that
can be heard by using headphone or speakers. and they also plan to develop its
various language versions. "This is like a Braille slate. It is
similar to that. We can use it without any problem.
