Measuring Method and Evaluation of Interpersonal Distance Using RTK-GNSS During Parent-Child Outdoor Activity

Abstract

This paper focuses on interpersonal distance as a form of non-verbal communication, and proposes a method using RTK-GNSS as a method for measuring interpersonal distance in children’s outdoor play for use in developmental support therapy for children with autism spectrum disorder. Preliminary distance measurement experiments using the proposed method showed its practical feasibility, and measurement experiments were conducted with typically developing children. The experimental results showed that the proposed method has practical feasibility, since the results of the experimental measurements showed a trend consistent with the observations by experts, similar to the Observetion method.
