Impact des préférences sensorielles chez les individus souffrant de troubles du spectre autistique sur leur interaction sociale avec un robot

Abstract : The goal of this thesis is to provide contributions that will help in the long term to enable personalized robot-based social interaction for individuals with Autism Spectrum Disorders (ASD). This work was done in collaboration with three care facilities for people suffering from ASD: IME MAIA (France) and IME Notre Ecole, medical and educative schools for children and teenagers with ASD, and FAM La Lendemaine (France), a medical house for adults with ASD.Inter-individual differences are present in ASD, and impact the behaviors of each individual in their lives, and in this study, during their interactions with a robot.The first step of our work was to propose an appropriate method to define the proprioceptive and visual profiles of each of our participants. We based our work on the hypothesis that the proprioceptive (the ability of an individual to determine body segment positions (i.e., joint position sense and to detect limb movements in space) and visual integration of cues of an individual with ASD is an indicator of their social and communication skills. We posit that a mitigated behavioral response (i.e., hyporeactivity) to visual motion and an overreliance on proprioceptive information are linked in individuals with ASD to their difficulties in integrating social cues and engaging in successful social interactions.We used two methods to define the proprioceptive and visual profile of our participant: a well-known questionnaire on sensory preferences and an experimental setup. With the setup, we were able to observe three different groups of postural behaviors in our participants. Thanks to these individual profiles, we could make assumptions on the behaviors that one can expect from each of our participants during interactions with the robot.We aimed to assess various social skills of our participants in regards to their profiles. We designed three single case studies: (1) emotion recognition with different embodiments (two robots, a virtual agent and a human); (2) a short greeting social task with the robot Nao; and (3) a game evaluating joint attention response to the robot Nao. We also conducted eight weeks-long sessions with an imitation task with Nao.Through these studies, we were able to observe that the participants that display an overreliance on proprioceptive cues and a hyporeactivity to visual cues had more difficulties to interact with the robot (less gaze towards the robot, less answers to joint attention initiation behaviors, more difficulties to recognize emotions and to imitate a partner) than the other participants.We were able to observe that the repeated sessions with the robot Nao were benefic for participants with ASD: after the sessions with the robot Nao, the participants showed an improvement in their social skills (gaze to the partner, imitations).Defining such individual profiles could provide promising strategies for designing successful and adapted Human-Robot Interaction for individuals with ASD.
