Just because a person uses an AAC device doesn't mean she can't also use speech, gestures, or other forms of communication. She doesn't have to pick one or the other - she can use ALL.
One device/strategy may not (and doesn’t have to) meet all needs.
Communication needs change across time, partners, and environment. Someone could be successful using verbal speech with his family, but need more help (like a low-tech communication board) to talk to new people at a restaurant.

AAC supports help when a condition prevents a person from communicating verbally.
For example, patients in the hospital may use an alphabet spelling board to communicate when they have a breathing tube preventing them from speaking.
Children may use AAC while they are working to develop or improve their spoken speech. Later, they may not need these same supports.
AAC can help people who have chronic or ongoing conditions.
AAC approaches can be used across the lifespan, but the specific strategy or device will probably change across time.

Examples of Low Technology AAC

Making your own communication boards can be easy!
Here are some helpful tips:
Use the "Visuals Engine" on
to design and print your communication boards. Create a
log-in to use this resource. It lets you make boards with 1-16 images per page. You can use their pictures, or upload your own. You can even add a text label.
Download and install the Picto-Selector program (
) on your computer. This free software gives you access to 1000s of picture symbols. It also allows you to use your own photographs and re-arrange the boards as many times as needed. You can save the file to make changes later. You can also save or print as a PDF file.
Find pictures in newspapers, magazines, or circular advertisements. Just cut them out and tape or glue them to your communication board or book. This works especially well for pictures of foods or objects (e.g., toy, tv, movie).
Examples of Mid Technology AAC
Did you know some stores carry recordable products that can also be used as AAC!

Alternate access allows people to interact with and control their world, even with limited use of their hands! Switches give people the power to use small movements (or even breath) to activate devices. Switches can be used to access communication devices or for environmental control (e.g., turn on/off lamp, radio, change TV channel).
To learn more about switches, see the Presentation below (or view the handout
Alternate access requires creative problem-solving to find the right position for the person (and the switch). Let's Play-Buffalo offers some ideas for positioning switches in this
What is functional communication?
Participating productively in interactions with other people requires functional communication skills (National Joint Committee for Communicative Needs of Persons with Severe Disabilities, 1992).
Individuals who have functional communication skills have the ability to communicate for a variety of purposes (e.g., give directions, share opinions, ask for a drink) to a variety of people (e.g., strangers, friends, family) relevant to their life experience.
Functional communication skills include having the ability to use a variety of modes, or ways, of accomplishing communication goals (e.g., waiving, writing, speaking).
An individual with functional communication skills is able to begin, maintain and end social interactions effectively.
For many communicators functional communication occurs everyday in real life or natural settings.
For individuals with complex communication needs, achieving functional communication often requires implementation of AAC strategies and tools.
