The purpose of this paper is to propose and examine the feasibility of the robot-assisted intervention system for facilitating the eye contact of the children with autism spectrum disorder (ASD). The treatment system was based on the discrete trial teaching (DTT) protocol with three task modes of treatment process; reward, encouragement, and pause. In child-robot interaction architecture, the robot was designed to offer 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. We compared the reactivity of the children depending on the diagnostic groups (3 subjects with ASD and 3 subjects with non-ASD) and on the type of robotic stimuli (K, D, and KD) type. Also, we surveyed the parents’ subject satisfaction and children’s friendliness to the robotic stimuli using the questionnaire developed by research group. As the results, the children’s response showed difference depending on the diagnostic group and type of stimuli in terms of response time and gaze ratio, though statistical analyses were unavailable due to small sample size. The treatment process and robotic stimuli showed high level of user satisfaction. The results suggest that the reinforcement and facilitation using robotic stimuli are generally feasible to incorporate into the standard treatment process
