A Method to Transmit the Message
AAC users may convey their message through visual and/or auditory output. With manual signs/gestures or communication boards the listener must watch the individual to interpret the message. Many electronic devices provide voice output (either computer generated or recorded) or a written display. AAC aids fall into three categories:

AAC devices range in complexity. They may include one symbol at a time that is available to the user, or may be more complex devices which use a sequence of icons to represent different concepts.

Communication Boards and Books
Communication boards or books are generally inexpensive and can be modified to meet varying situations. Users may point to or remove symbols to express messages. They can be taken anywhere, are easy to use and durable. There are many options to allow users to access communication symbols: including single boards, large or small notebooks,rings, caregiver vests or aprons. Participation is enhanced when multiple limited context communication displays are available. Mini displays can be mounted in specific locations such as on the wall, the dashboard of the car, and the pages of a story, so the person can communicate wherever they are. Minboards for specific events can be constructed and stored until the next occasion. Pictures mounted on a transparent acrylic board may be used for a person with limited mobility to indicate their messages through eye gaze.
