On the Adaptability and Applicability of Multi-touch User Interfaces Addressing Behavioral Interventions for Children with Autism

Abstract

Principles of human-computer interaction (HCI) are imperative when it comes to efficient user interface design. This becomes even more significant when the interface is for users with special needs and especially when there is a treatment methodology incorporated in a piece of software. This study investigates user interfaces that are specifically made for children with autism-spectrum disorders. We conducted a survey to evaluate the adaptability and applicability of various interfaces. For this, we selected four of the behavioral interventions for autism namely discrete trial training (DTT), cognitive-behavioral therapy (CBT), empathy enhancement and verbal behavior approach (VBA). User interfaces (UIs) of 16 software applications were assessed for the said features. Results of this assessment revealed that these Applications were adaptable to two behavioral interventions, on the average. Moreover, these Applications were simultaneously applicable for treatment of three levels of autism; namely high functioning, low functioning, and autistic adults. These interfaces were also applicable to the children with no autism (typically developing) who acted as a controlled group.
