Autism spectrum disorders (ASD) are characterized by a reduced ability to understand the emotions of other people; this ability involves recognizing facial expressions. This study assessed the possibility of enabling three adolescents with ASD to become aware of facial expressions observed in situations in a school setting simulated using augmented reality (AR) technology. The AR system provided three-dimensional (3-D) animations of six basic facial expressions overlaid on participant faces to facilitate practicing emotional judgments and social skills. Based on the multiple baseline design across subjects, the data indicated that AR intervention can improve the appropriate recognition and response to facial emotional expressions seen in the situational task.
