Interpersonal distance and face-to-face behavior during therapeutic activities for children with ASD

Abstract

This study proposed a quantitative estimation method for interpersonal distance by using a prototype measurement system. With the aid of motion capture technology and marker caps, we estimated the body position and orientation of children with autism spectrum disorders (ASD) and their therapists. A prototype measurement system was introduced in practicing therapy rooms and captured behavior during ongoing therapy for children with ASD. This study confirmed that approaching behavior and, to a lesser extent, interpersonal distance can be effectively estimated using the proposed motion capture system. Additional system improvements are required to capture face-to-face behavior.
