High Tech and Low Tech AAC: How to Effectively use both

With high tech AAC systems, the possibilities are truly endless when it comes to providing a voice to those with communication deficits. From remote therapy (teletherapy) to literacy supports, high tech AAC seems to have it all. It makes you wonder if low tech AAC devices are still relevant and useful for children with communication challenges. 

What is Low Tech AAC?

Augmentative and alternative communication (AAC) is a term referring to all communication other than natural speech. Low-Tech AAC comprises tools and strategies that do not involve electronics and do not require batteries. Examples of Low-tech AAC are PECS (Picture Exchange Communication System), symbol charts, communication boards, communication books, etc.

Low-Tech Vs High-Tech AAC

Most high tech systems are compatible with social media and messaging platforms which allows more learner engagement. They also facilitate communication autonomy by giving the user a wide choice of vocabulary that supports a variety of communicative functions.

More importantly, high tech AAC devices support SNUG (Spontaneous Novel Utterance Generation) which allows an individual to say whatever they want to, whenever they want to.

A robust AAC system also supports the language development and literacy acquisition of a communicator in addition to building communication.

Why a Multi-Pronged Approach Might be the Right Formula

Communication is complex and we constantly use several modes of communication to get our message across to others. We use facial expressions, gestures, and body language in addition to our speech to communicate. Similarly, people with communication challenges could potentially use multimodal communication to convey their messages.

Taking away their means to communicate can leave people feeling helpless and frustrated. So, users must be encouraged to choose multiple modes of communication. When used in conjunction with high tech systems, low tech AAC devices can be a powerful communication solution for people with complex communication needs.

Low-tech AAC (Augmentative and Alternative Communication), including laminated communication charts, is useful in demanding environments like pools and beaches. You can also use low tech AAC as a backup communication mode in case the high tech AAC systems run out of charge, or are not functional. You can take a printout of your child’s vocabulary and keep it in your bag or car for quick accessibility.
