What is Low Tech AAC?

Low-Tech AAC (Augmentative and Alternative Communication) comprises of 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.

The user selects letters, words, or phrases from the communication charts to convey their message. Users can use a body part such as their finger or toe, a head pointer, eye gaze,  mouth stick, light pointer or a hand-held pointer for the selection.

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.

Low-tech AAC, 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.

Avaz AAC app, for instance, has a handy feature where you can print out a child’s personal vocabulary from the app itself. 

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.
