The goal of this project is to develop a virtual reality technology in the form of computer-assisted, photo realistically animated simulations to augment social skills interventions for school-age children and youth with mild to severe autism spectrum disorders. This Phase 1 Development Project will write 10 social narrative 'scenarios,' which will then be imported into programmed finite machine-state packages. These packages will allow users to select a social predicament, witness it unfolding, and make a response or series of responses. The nature of the user's response will tell the computer to change states, resulting in a follow-up scenario, user response, and change-in-state. Social narratives will be drawn from a panel of content experts who will generate and confirm social narrative content as well as 'mark up' such social characteristics as hand/arm gestures, facial expressions, and vocal features. These simulations can be animated with photorealistic human characters that will move and interact in three dimensional (virtual) reality.
