6. The braille system

Braille is a tactile aid that allows visually impaired people to read and write.

Louis Braille, a visually challenged person, developed the braille system. The present Braille System was adopted in the year \(1932\).

Many Indian languages can be read using the braille system.

In the Braille code system, there are \(63\) Dots or \(63\) Characters.

Visually impaired people learn the braille system by beginning with letters, then special characters and letter combinations. Methods depend upon recognition by touching.

Each character has to be memorized by visually challenged people. When they touch the braille texts, they can recognize what is written in the material.

Braille is read by moving the hand or hands along each line from left to right.

Reading is generally done with both hands, with the index fingers doing the majority of the work.

Reading speed is around \(125\) words per minute on average. However, higher speeds of up to \(200\) words per \(minute\) can be achieved.
