There is a growing gap between the number of children with autism requiring early intervention and available therapy. We present a portable platform for pervasive delivery of early intervention therapy using multi-touch interfaces and principled ways to deliver stimuli of increasing complexity and adapt to a child's performance. Our implementation weaves Natural Environment Tasks with iPad tasks, facilitating a learning platform that integrates early intervention in the child's daily life. The system's construction of stimulus complexity relative to task is evaluated by therapists, together with field trials for evaluating both the integrity of the instructional design and goal of stimulus presentation and adjustment relative to performance for learning tasks. We show positive results across all our stakeholders-children, parents and therapists. Our results have implications for other early learning fields that require principled ways to construct lessons across skills and adjust stimuli relative to performance.
