A-Rrounding Relay is a toy designed to enhance attention and cognitive order in children with ADHD through cooperative play and Sensory Integration Training,providing social companionship for ADHD children. The ball runs aroud with the gyroscope. The central indicator lights up yellow or green randomly, reminding the child to put the corresponding track before the ball reaches the fracture. Movement of the turntable with building block feeds back the time that ADHD children persist in the whole play process. After the game, children can use the blocks they get to create patterns they like.
