Optimized User Experience Design for Augmentative and Alternative Communication via Mobile Technology: Using Gamification to Enhance Access and Learning for Users with Severe Autism

One of the most significant disabilities in autism spectrum disorder (ASD) includes a delay in, or total lack of, the development of spoken language. Approximately half of those on the autism spectrum are functionally non-verbal or minimally verbal and will not develop sufficient natural speech or writing to meet their daily communication needs. These individuals receive intervention in the area of augmentative and alternative communication (AAC) using mobile technologies. AAC services ideally should be provided starting at an early age but many young learners experience some degree of difficulty in gross and fine motor functioning that prevents accessing and benefitting from mobile AAC applications.
