A robotic treatment approach to promote social interaction skills for children with autism spectrum disorders

In this paper, we propose with a robot-assisted behavioral intervention system to easily improve children's social capability. In particular, the system for children with autism spectrum disorders (ASD) is basically achieved through the discrete trial teaching (DTT) protocol with three task modes of therapy, encouragement, and pause in social training scenarios. In child-robot interaction architecture, the robot firstly offers therapeutic training elements of mutual greeting and interplay game, and evaluates the level of children's reactivity by recognition modules for frontal face and touch features. Thence, the system in the decision-making process determines the task mode to perform subsequent action by grasping behavioral state of the children, and then it copes with individual response appropriately by using the robotic stimuli with the combination of kinesic acts and displayable contents. From the experiments of clinical trials with children with non-ASD and ASD in each robotic stimulus, the system showed the potential to increase their attention and activeness for social training, and we believe that the proposed system has some positive effect on developing children's social skills.
