Technology does not need to be complex to work well. Hugh Murtagh from Coláiste Mhuire in Co Westmeath has designed wristband that will help students with Autism alert their teachers in a subtle manner when they feel they need a break from the class.
As simple as a wristband you can push, like an Amazon Dash button, and a notification is sent to the teacher. Simple, subtle, effective.
