Signing Exact English (SEE)
A sign system that matches signs with the English language.
Tactile American Sign Language (formerly called Manipulated or Modelled Sign Language)
Used primarily by deaf deaf-blind people who use ASL by holding the hands of the other conversational partner and feeling the hand movements.
Alphabet Based Systems
Fingerspelling: A form of sign language in which individual letters are formed by the fingers to spell out words
Two-Hand Manual: Letters of the English alphabet are formed by a speaker’s hand positions which are placed upon a recipient’s open relaxed palm.
Print on Palm (POP): Printing large, capital letters on an individual’s palm
Print on Paper: Printing large capital letters on paper for individuals to read
Braille: A system of raised dots that can be read with the fingers by people who are blind or who have low vision
Moon Print: A code of raised shapes that corresponds to letters of the alphabet for people who are blind or have low vision
Object Cues: Cues are given to the individual who is deafblind in a predetermined order to communicate specific concepts, ideas and tasks.
Communication Boards: A display of English words or alphabet tactile symbols, art, pictograph symbols, etc. and is used to encourage the individual who is deafblind to communicate with individuals in their surroundings
Speech Based Systems
Voice Over: Words spoken in a tone, speed and volume that makes it able for the person who is deafblind to be able to hear what is being said.
Speech Reading: Looking at the speaker’s lips and through visual and contextual cues and exaggerated enunciation and lip movements gather an idea of what is being said.
Tadoma: The person who is deafblind places his hand on the face of the speaker, the thumb gently touching the lips and the other fingers spread over the cheek, jaw and throat.
Hearing Aids: Assistive devices that individuals wear in their ear that amplify voices and noises in the environment.
Cochlear Implants (CI): Devices that are surgically implanted into an individual’s ear that is hooked up to a transmitter. This allows individuals who have severe or profound hearing loss to be able to hear speech and/or environmental noises.
