We are developing a learning support system for zoos that enables children to learn through body movements. For children, the zoo is an important place for science education outside of school. However, learning methods in zoos are mainly limited to observing exhibits and explanations. In addition, when children want to observe animals that are hiding, they can neither touch nor observe them. Therefore, in this study, we develop a body-experience-based learning support system that can be applied in zoos. The system measures the learners' body movements using a sensor, and provides a sense of immersion in the environment where animals live by adapting the surroundings based on these movements. In the first stage of this project, we have developed a prototype that allows learners to jump with animals, and enables children to efficiently learn animals' physical characteristics. In this paper, we describe the results of our experimental evaluation of by measuring physiological responses.
