Design of Blind Assistance System Using Refreshable Braille Display

Abstract

In this paper, we demonstrate that Braille embosser is a type of device which is very useful
for the initial stage Braille language learner. Here the input is provided with the help of
serial port by mobile through Bluetooth module. This input is in the form of alphabetical
form so the input is converted into Braille language which is displayed with the help of
actuators. Blind assistance system also allows visually impaired people to do common tasks
such as reading in Braille and reading documents. It is a portable device, they can carry
wherever they want so that they could get information of place they are visiting with ease. As
this device detect the obstacles and also determine at what distance obstacle is person can
safely use this device for indoor purpose.
