Unaided

Since unaided AAC only requires the use of the individual’s body, the two main considerations for using this type of system are the physical and cognitive abilities of the person with complex communication needs.

Physical ability: The scope of physical movements affects the amount and/or type of communicative messages that can be expressed. When evaluating an individual with complex communication needs

Cognitive ability: Unaided AAC does not provide the same type of visual supports available with aided AAC and therefore may be cognitively more difficult for an individual.
