An Optical See-Through Augmented Reality System for the Treatment of Phobia to Small Animals

摘要

This paper presents an optical see-through (OST) Augmented Reality (AR) system for the treatment of phobia to small animals. Our group has already presented two AR systems for this treatment. The first system was a video see-through (VST) AR system. The second one was a markerless AR system. And now, we present a third version using an OST approach. To check whether the OST AR system is more or less effective than the OST AR system, we have carried out an experiment comparing both systems. In this paper we focus on the anxiety level of participants during the experiment. Results show that both systems provoke anxiety in participants even if they do not have fear to cockroaches/spiders. OST AR system provokes slightly more anxiety than the VST AR system.
