Abstract
Approximately 1 in 160 children worldwide is diagnosed with Autism Spectrum Disorder (ASD). ASD prevalence is on the rise in the United States. Virtual reality (VR) techniques have been tried in several studies to improve the shopping skills of people with ASD. However, in these VR applications, the effectiveness in training people with ASD in shopping has never been tested in the real-world environments. Our studies show that individuals with ASD become anxious when exposed to a new environment such as a supermarket, without knowing what to do next. Also, VR applications are less accessible, portable, or affordable compared to the emerging mobile augmented reality (AR) applications. Therefore, we have created a mobile AR application that augments real shopping scenes with visual-audio annotations via object recognition, barcode reading, and automatic categorization. Through a user-friendly visual interface, the app can help people with ASD learn shopping skills effectively, by guiding them through the shopping process step by step in a real environment with AR.
