Continuing on the previous post, we would like to look at another device that has helped the visually impaired. Braille is a tactile writing system used by the visually impaired. There is an interesting innovation based to this called “Refreshable Braille Display”.This is a device which helps in displaying Braille characters. It has to be connected to the computer via a USB cable. Once connected to the computer, the Braille display acquires the highlighted words and translates into braille characters. The Refreshable Braille Display enables its users to see or read anything on electronic gadgets. They can write braille characters with the original slate and stylus or type it on a braille writer, such as a portable braille note taker or computer that prints with a braille embosser.
