Interactive robots for communication-care: a case-study in autism therapy

摘要

The paper proposes possible use of interactive robots in the remedial practice for children with autism, who have difficulties mainly in interpersonal communication. For this purpose, we built a small creature-like robot, Keepon, which was carefully designed to get autistic and non-autistic children involved in playful interaction. We observed how autistic children (2-4 years old) interacted with Keepon without any experimental setting or instructions in a playroom at a day-care center for children with special needs. From the longitudinal observation for a year and a half (totally, over 500 child-sessions), we found that Keepon's simple appearance and predictable responses gave the autistic children a playful and relaxed mood, in which they spontaneously engaged in dyadic play with Keepon, which would then expand into interpersonal communication where Keepon worked as the pivot of triadic play with adults or other children. Each child showed a different style and a different unfolding of interaction over time, which tell us a "story" of his or her personality and developmental profile, which would not be explained thoroughly by a diagnostic label like "autism".
