Measuring the Efficacy of Robots in Autism Therapy

A significant amount of robotics research over the past decade has shown that many children with autism spectrum disorders (ASD) have a strong interest in robots and robot toys, concluding that robots are potential tools for the therapy of individuals with ASD. However, clinicians, who have the authority to approve robots in ASD therapy, are not convinced about the potential of robots. One major reason is that the research in this domain does not have a strong focus on the efficacy of robots. Robots in ASD therapy are end-user oriented technologies, the success of which depends on their demonstrated efficacy in real settings. This paper focuses on measuring the efficacy of robots in ASD therapy and, based on the data from a feasibility study, shows that the human-robot interaction (HRI) metrics commonly used in this research domain might not be sufficient.
