User interface adaptability within an augmentative communication app for children with autism spectrum disorder

Abstract

Facilitating communication is considered the first step to developing learning interventions for individuals with autism spectrum disorder. The introduction of tablets and augmentative communication apps is changing the way that communication is being approached. There is presently no clear set of criteria to identify which interface settings could work best for each individual. This study focused on the user interface of Proloquo2Go and specifically looks at the effect that button size and array size has on the usability of the app for individuals with autism spectrum disorder. It was found that 2 of 3 participants exhibited similar response rates and patterns of use with the app, showing low influence of button size and array size. Further research is needed in the area of user interface characteristics for individuals with autism spectrum disorder to draw solid conclusions about a relationship between button size/array size and usability for these individuals.
