What kind of systems does Low Tech Systems in AAC include?

Low Tech Systems in Augmentative and Alternative Communication (AAC) primarily refer to communication methods that are straightforward, accessible, and do not require complex technology or power sources. This includes the use of simple communication boards or picture systems that allow individuals to express their needs, wants, and thoughts through symbols, images, or combinations of both.

These aids are often tangible and can be made from materials like paper or cardboard, making them easy to use and implement in various settings. Their simplicity is a key advantage, especially for individuals who may struggle with more technologically advanced alternatives. Low Tech Systems provide an essential means for effective communication without the barriers that electronic devices might impose, ensuring that users can engage meaningfully in conversations and social interactions.

The other options represent different classifications of communication technologies. Devices that require power sources or electronics are considered high-tech systems, and this includes sophisticated speech-generating devices. Highly complex technologies for speech generation add another layer of intricacy and typically involve advanced software and hardware, which separates them from the straightforward nature of low-tech systems. Lastly, non-verbal communication through expression only does not fit within the AAC framework, which emphasizes the incorporation of tools and systems to facilitate communication beyond verbal skills.
