AAC app for children with Autism

Speech Scientist Ajit Narayanan presents his findings on language development and how using visuals and language "mapping" can increase expressive language, across any spoken language. He has also created an iPad application that he believes helps non-verbal children learn and use language and it can be especially useful for children with Autism. 
As we know, children with Autism are high visual learners and I am excited to see how this progresses!
