The AAC Files: "Low Tech" AAC

"Low tech" AAC is essentially any sort of communication method that is not an "electronic," but it requires some sort of equipment outside one’s body. It can be as simple as a pen and a piece of paper, or as involved as a communication book made up of many pages. As mentioned in other posts, many individuals who use "low tech" AAC devices for communication also use other types of AAC.

First things first, what are some examples of "low tech" AAC?

Pen and paper: an individual can write or draw their messages. A portable whiteboard or Boogie Board (LCD tablet) is another option.

Alphabet board: an individual can point to letters/numbers to spell their message for their communication partner (i.e. someone an individual communicates with on a regular basis, whether it be a parent, caregiver, nurse, etc.).

Core words board: a few basic symbols an individual can point to in order to communicate their message. Core words boards are typically laminated pieces of paper.

Pictures/symbols: a few symbols (similar to those on a core words board) on different cards or laminated squares an individual can hand to their communication partner to communicate their message.

Communication book: multiple pages of symbols, often grouped by category (e.g., food, toys, places) with familiar vocabulary to the individual whom it belongs to.

Who would use a low tech AAC device?

Anyone who is unable to communicate effectively (taking developmental milestones into consideration) would benefit from some form of "low tech" AAC. In the world of speech-language pathology, individuals with autism, down syndrome, intellectual disabilities, and/or developmental disabilities may benefit from "low tech" AAC. Additionally, individuals who have brain injuries, aphasia, or progressive/degenerative conditions may also use a "low tech" AAC device. As you may have gathered, the scope is broad.

Why would someone use a "low tech" AAC device as opposed to another form of AAC?

Sometimes, a "no tech" AAC system (head nods, gestures, etc) is not enough to communicate effectively. A "low tech" AAC system consisting of pictures, symbols, or a core words board provides more ways for an individual to communicate.

"High tech" AAC devices (think tablets, iPads) can be incredibly effective for individuals in most situations, but what if an individual is in a pool? It is probably not wise to have an electronic device that could sustain water damage next to the pool, but a laminated communication book could be used for this situation. Individuals with "high tech" AAC systems may benefit from having a "low tech" AAC system as well.

Some individuals may not be a proper candidate for a "high tech" AAC system, secondary to physical and/or cognitive impairments. They may not be able to communicate more than a few messages, so a few symbols (more, finished) or choices may be adequate for them.

What else do I need to know?

It is important to remember that these types of AAC systems may be temporary. An individual may change, and their communicative needs may change as well. For example, their ability to communicate may improve, and they are able to use spoken language; or their ability to communicate may decrease. This may happen if they have a degenerative condition and it progresses. In this situation, a more robust AAC system may be necessary for effective communication.
