AAC is not just about the individual using the system. In order for someone with Rett Syndrome to learn how to use a communication aid it must be consistently demonstrated to them in the same way as we expect them to use it. This is exactly what we do with normally developing children. As a child learns to point and indicate, we give meaning to their actions. Children with developmental delays through conditions such as Rett Syndrome need the same level of input, but facilitators need to presume what they would say in a certain situation and model it appropriately. In time we expect the AAC user to understand and use the same utterances appropriately.
The eyes are the best pointer for people with Rett Syndrome, which makes learning how to track their eyes a critical stage. Good vocabularies based on communicating in the “here and now” are important.
At Tobii Dynavox we have a number of vocabularies available in our software titles depending on your language, symbol preference, language level. All of our vocabularies feature TOPIC based pages allowing that instant situation based communication. Rather than make definite choices at an early stage, you can download all of our tools for trial, free of charge.
