Autism Spectrum Disorder is the fastest growing developmental disability today. Autism is a syndrome with a diverse set of symptoms--rarely consistent across diagnosed individuals, and requiring a combination of therapies, educational approaches, and treatments. There is no known cure for autism. Instead treatment is left to educators and therapists, who must adapt treatment to the specific needs of each individual student. The past 10 to 15 years has seen the application of many new technologies to autism. This article surveys technologies which have been or could be applied to diagnosis and assessment, therapy, social skills, affect and emotion processing, communication, managing problem behavior, and synthesizing data. Finally, the article suggests criteria for understanding the value of future technologies as they apply to the treatment and education of individuals on the autism spectrum.
