Parents, each with a Bluetooth device in their ears, sit in a play-based early intervention therapy session with their autistic child. As they interact through a series of exercises, they receive instruction, feedback and encouragement audibly through their earbuds. The voice talking to them is a community-based early intervention professional trained by a team of coaches led by Heather Coleman, UNC Greensboro Assistant Professor in the Department of Specialized Education Services. The goal: support early intervention therapists, who work with families of autistic children to help them better understand and communicate with each other.
