This paper presents a series of 4 single subject experiments aimed to investigate whether children with autism show more social engagement when interacting with the Nao robot, compared to a human partner in a motor imitation task. The Nao robot imitates gross arm movements of the child in real-time. Different behavioral criteria (i.e. eye gaze, gaze shifting, free initiations and prompted initiations of arm movements, and smile/laughter) were analyzed based on the video data of the interaction. The results are mixed (...) and suggest a high variability in reactions to the Nao robot. The results are as follows: For Child2 and Child3, the results indicate no effect of the Nao robot in any of the target variables. Child1 and Child4 showed more eye gaze and smile/laughter in the interaction with the Nao robot compared to the human partner and Child1 showed a higher frequency of motor initiations in the interaction with the Nao robot compared to the baselines, but not with respect to the human-interaction. The robot proved to be a better facilitator of shared attention only for Child1. Keywords: human-robot interaction; assistive robotics; autism. (shrink)

Many studies have shown that using robot platforms can be effective for teaching children with autism spectrum disorder (ASD). The aim of this study was to compare performance on an imitation task, as well as focus attention levels and the presence of social behaviours of children with ASD and typically developing (TD) children during an imitation task under two different conditions, with robots and human demonstrators. The results suggested that TD children did not imitate more than children with ASD. Children (...) with ASD did not imitate the robot more than they imitated a person, but they showed more focused attention to robots and expressed more social behaviours in interaction with the robots. Behaviours that were significantly more present in ASD children than in TD children included touching the robot in the robot demonstrator condition and focusing on the robot in the person demonstrator condition. This implies a possible preference of children with ASD towards robots rather than towards people. (shrink)

The use of robots in therapy for children with autism spectrum disorder raises issues concerning the ethical and social acceptability of this technology and, more generally, about human–robot interaction. However, usually philosophical papers on the ethics of human–robot-interaction do not take into account stakeholders’ views; yet it is important to involve stakeholders in order to render the research responsive to concerns within the autism and autism therapy community. To support responsible research and innovation in this field, this paper identifies a (...) range of ethical, social and therapeutic concerns, and presents and discusses the results of an exploratory survey that investigated these issues and explored stakeholders’ expectations about this kind of therapy. We conclude that although in general stakeholders approve of using robots in therapy for children with ASD, it is wise to avoid replacing therapists by robots and to develop and use robots that have what we call supervised autonomy. This is likely to create more trust among stakeholders and improve the quality of the therapy. Moreover, our research suggests that issues concerning the appearance of the robot need to be adequately dealt with by the researchers and therapists. For instance, our survey suggests that zoomorphic robots may be less problematic than robots that look too much like humans. (shrink)
