Communication Methods for the Visually Impaired: Braille & Sign Language

There are a number of different languages that blind people use to communicate, including:

- Braille: Braille is a tactile system of writing and reading in which raised dots on a page are read by touch. It was invented by Louis Braille in the 1820s, and it is now used by blind people all over the world.

- Sign language: Sign language is a visual language that uses gestures, facial expressions, and body language to convey meaning. There are many different sign languages, each of which is unique to a particular country or region.

- Tactile sign language: Tactile sign language is a form of sign language that is used by people who are both blind and deaf. In tactile sign language, the sender uses their hands to sign directly onto the receiver's hands, so that the receiver can feel the gestures and understand the message.

- Lip reading: Lip reading is a skill that allows people to understand speech by watching the speaker's lips and facial expressions. Lip reading can be a helpful communication tool for people who are deaf or hard of hearing, as well as for people who are blind.

- Auditory aids: Auditory aids, such as hearing aids and cochlear implants, can help people who are deaf or hard of hearing to hear and understand speech.
