AAC includes equipment and services that enhance face-to-face communication and telecommunication. Writing aids are also included in AAC.

The devices allow an individual to communicate when traditional speaking and writing are not effective. AAC equipment is customized to address a user’s motor and communication needs.

“…the combination of communication tools available to an individual, including any speech, vocalization, gestures, and communication behaviors related to specific methods and devices.” (Johnston et al., 2007 p. 116).

According to Benson (2003) AAC can either supplement,

enhance or replace conventional methods of communication (Johnston et al. 2007, p. 102)

Augmentative communication devices “add to”, “assists”, or “supplements” an individual’s present communication skills.

Alternative communication devices are ones that “by pass” or “replace” an individual’s oral communication system altogether

Discussion: Turn to the person next to you and provide an example of each of these communication devices. Discuss how AAC systems can enhance an individual’s speech and language development.

Based on the student’s physical, cognitive, sensor, and receptive language skills

Selection of AAC devices should be a team’s decision, especially with input from the student, an SLP, and an AT specialist

The team should assess both the student and their environment to select the most appropriate AAC device.

Refer to the SETT framework and Chapter 3:

Communication Power Point from www.wati.org on the wiki

What is the goal for selecting and implementing AAC devices?

A technique an individual uses to make their message known (Johnston et al. 2007, pg. 103)

Scanning

Encoding

Direct selection

Devices used by an individual to supplement, enhance, or replace communication (Johnston et al., 2007)

1. Provide a supportive environment2. Challenge the student3. Keep open communication between team

members4. Participate in ensuring the student is

successful using the AAC device5. Follow IEP6. Use simple strategies first (low tech to high

tech)

What size keyboard would be most beneficial to meet the student’s needed?

How much pressure will be required to press the keys? How much space between keys would be most beneficial to

meet the needs of the student? What adaptations are needed to use two keys

simultaneously? Will the user need visual or tactile cues? Is moisture in the keyboard area a potential problem? Can the student reach and target the keys? Can keys be released quickly to avoid repetition of

depressed key?
