Riassunto analitico
Individuals with Autistic Spectrum Disorders (ASDs) have impairments in the processing of social and emotional information. The<br>number of children known to have autism has increased dramatically since the 1980s. This has sensitized the scienti¯c community to the<br>design and development of technologies suitable for treating an autistic patient in order to broaden the emotive responsiveness, such as<br>the employment of robotic systems to engage proactive interactive<br>responses in children with ASDs.<br>My PhD work focuses on the design and develop of new technologies<br>for therapy with individual affect by ASD. The main challenge of my<br>work has been to design and develop a novel control architecture able<br>to reproduce the brain characteristics in terms of high concurrency processing, flexibility and the ability to learn new behavior. The<br>main di±culties in implementing Artificial Neural Networks (ANNs)<br>in hardware in terms of accuracy, gate complexity and speed performance are discussed.<br>A new wearable eye tracking system able to investigate attention<br>disorders early in infancy is proposed. Technological choices are emphasized with respect to unobtrusive and ecological to adapt the<br>device for infants. New algorithms to increase the system robustness under illumination change and during calibration process have<br>been developed and herein presented. Experimental test prove the<br>effectiveness of the solutions.<br>Considerations on the future research directions are addressed, stressing the multiple application fields of the designed device.
