Implementation of new assistive technologies for people affected by Autistic Spectrum Disorders (ASDs)

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