Assistive Technology for Communication
The term augmentative alternative communication (AAC) or “aug. comm.” is often used when referring
to the use of some means other than natural speech to communicate. This is a complex area with many
variables. In beginning to understand it, let us look first at the various systems and devices that can be
used to augment communication.
Simple Communication Boards
♦ Communication boards consisting of objects or parts of objects, miniature objects, pictures, or
graphic symbols,
♦ Communication boards may consist of one, a few, or many pictures.
♦ They may be of various sizes depending upon user ability.
♦ Various displays or arrangements may be used to increase “effectiveness” of communication
interactions.
♦ They may be used as an AAC option for a young child or an individual with very limited vocabulary
or as a back up to a more complex voice output device.
♦ Simple communication boards are also used for “aided language stimulation”. Aided language
stimulation is the process in which the partner points to picture symbols on a simple communication
board in conjunction with ongoing verbal language stimulation.
♦ Often individual communication displays are made for specific activities or to use in the community
or in congested or noisy environments where a voice output device may not be effective.
♦ Picture communication symbols are often generated using software like Boardmaker from Mayer-
Johnston, Inc. Images and clip art from other sources may also be used for picture communication
systems.
Examples: Object boards, communication wallets/books, displays created with single or
multiple photos, symbols, etc.
Back up: Make additional copies of the communication boards and keep a record of the
vocabulary which is used on those boards in case the original boards get
destroyed or lost.
Eye Gaze Frame or Board
This is a system where objects, pictures, or symbols are placed in such a way that the student can
communicate by looking at the desired item. A vertical frame is frequently made out of PVC or CPVC
pipe with the pictures or other items placed several inches apart around the frame. This allows a
communication partner to sit facing the student and see very accurately where the student is looking as
he gazes at the desired object or picture to communicate a choice or interest. WATI has designed and
sells a clear acrylic eye gaze frame that is free standing and folds when not in use.
