Alphabetic Systemes

Definition: Any communication system used based on the letters of the alphabet

Some examples of alphabetic systems: :

  • Braille (alphabet used by the visually impaired)
  • Gestual Alphabet (used by the deaf)
  • By-the-si-lab (association of syllables to convey a message)
  • Alphabet (the classic alphabet printed on a cardboard sheet)

Highlights of these systems:

  • Fine and precise communication
  • Remote communication possible (letter), except for the sign language alphabet.
  • Unlimited message composition

Weak points of these systems:

  • Requires excellent mental skills
  • Ability to read and write
  • Very slow (often supported by availability word prediction)
