Development and evaluation of a social robot platform for therapy in

  1. Development and evaluation of a social robot platform for therapy inautism<br />Daniele Mazzei, University of Pisa<br />EMBC11Boston 29th August - 3thSept 2011<br />
  2. ASDs and Robotics<br />One of the main difficulties in subjects with autism spectrum disorders (ASDs) is their inability to understand and analyze the emotional state of their interlocutor. <br />Recent research shows that ASDs perceive robots not as machines, but as their artificial partners <br />
  3. Our Hypothesis<br />A therapist guided interaction between a robot able to express emotions and ASDs can help them to improve social skills.<br />The FACE of Autism, Mazzei et. All, ROMAN2010, Viareggio Italy, Sept. 2010<br />
  4. What we need?<br />
  5. The FACE Android<br />
  6. The FACE ‘mood’<br />Emotion Cartesian Space (ECS) based on the Posner theory called ”The circumplex model of affect”<br />
  7. FACET platform<br />FACE android<br />Gaze tracking hat<br />Sensorized T-Shirt<br />Face Control Unit<br />(Bodymap and brain)<br />Face tracking and facial expression recognition<br />Inertial platform<br />Room motorized cameras<br />Face configurator and control interface<br />Environmental microphone<br />
  8. FACET Software modules<br />
  9. Physiological signal acquisition<br />Based on e-textiles<br />HR, HRV, RR, skin conductance, skin temperature, respiratory rate and accelerations<br />All this signals can be correlated with subject emotional states<br />Made by Smartex Srl, Italy<br />Valenza, G et all., Towards a smart glove: Arousal recognition based on textile ElectrodermalResponse, EMBC10<br />
  10. HATCAM Eye Tracker<br />Wearable and specifically designed to investigate early attention disorders in infants<br />Hat or Band mounted system <br />fast and easy calibration procedure <br />Mirror allows to use images of both eyes (3D gaze point identification)<br />A.Armato, Implementation of new assistive technologies for people affected by Autistic Spectrum Disorders ASDs", Pisa May 2011. (Patent: TO2008A000862)<br />
  11. FACET platform<br />
  12. The FACET protocol<br />Phase A:Familiarization with the FACET room and the android<br />Phase C:Conversation with psycologist about FACE<br />Subject – Robot interaction<br /> 20 min<br />0 min<br />Phase B:Exposition and inteprretation of FACE’s expressions<br />Phase D:Conversation with FACE (if starts)<br />
  13. Preliminary results<br />At the moment this therapy/paradigm has been tested with 4 ASD subjects and 2 controls <br />No subjects showed discomfort or fear during the therapy<br />increased cardiac sympathetic activity was observed in ASDs.<br />
  14. Conclusions<br />Well accepted by ASDs<br />Could have a wide range of applications in the study of non-verbal communication and expression.<br />Can become an innovative therapeutic approach aimed to gradually increase social cognitive skills of ASDs.<br />
  15. Future Works<br />On going experiments on control and ASDs<br />More tests of the FACET hardware/software infrastructure<br />Using of the FACET platform to perform generic studies about human-robot empathic link <br />
  16. Future Works<br />Complete and integrate the face adaptive control algorithm trying to close the loop<br />
