AbstractThis paper presents a proof-of-concept of a robot that is adapting its behaviour on-line, during interactions with a human according to detected play styles. The study is part of the AuRoRa project which investigates how robots may be used to help children with autism to overcome some of their impairments in social interactions. The paper motivates why adaptation is a very desirable feature of autonomous robots in human-robot interaction scenarios in general, and in autism therapy in particular. Two different play styles namely ‘strong’ and ‘gentle’ are investigated experimentally. The model relies on Self-Organizing Maps and on Fast Fourier Transform to preprocess the sensor data. First experiments were carried out which discuss the performance of the model. Related work on adaptation in socially assistive and therapeutic work are surveyed. In future work, with typically developing and autistic children, the concrete choice of the robot’s behaviours will be tailored towards the childrens interests and abilities. The study provides proof of concept of on-line behaviour classification and adaptation of a robot’s behaviour according to human-robot interaction styles. Experiments have shown that with our proposed model of classification a) the Aibo is able to classify a dyadic human-robot interaction it is involved in on-line, and b) it can adapt to the interaction by changing its own behaviour and thus changing the interaction with the subject. Concerning the process of the Aibo changing its own behaviour, more investigations needs to be done to define more accurately the different relevant behaviours for the context of child-robot interaction and more specifically for the Au- RoRa project, i.e. in a therapeutic context involving autistic children. As already mentioned above, in future work with typically developped and autistic children, the concrete choice of these behaviours will be tailored towards the childrens interests and abilities.
