Movement imitation underlying coaching platform for children with ASD

This paper presents a movement imitation platform which offers a natural way for coaching children with autism spectrum disorder (ASD). The system is built up by a NAO humanoid robot that mimics the upper limb movement, and a depth camera that captures the action of human. We use skeleton tracking data of upper limb with SDK, and then calculate the joint angles and positions of the upper limbs; The posture parameters of upper limb are scaled and then transformed into those of the NAO robot´ joints. The tests on both normal adults and children with ASD show that the system performs robust for upper limb imitation¹.
