ABSTRACT
Abstract This chapter considers the role of theory in design and how it can be used to better support technology to improve quality of life for individuals with autism and their caregivers. It also provides a review how theory has been used by human computer interaction (HCI) researchers from the beginning of the discipline to now. Finally, Urie Bronfenbrenner’s Ecological Systems Theory is proposed as another theory that can be used by HCI researchers. A set of examples are provided that show how this theory can be used to aid design.
