HyperMirror is a tool that aims to create a shared space that facilitates collaborative activities. In contrast to traditional videoconferencing systems, HyperMirror allows local and remote participants to feel as if they are in the same room, share materials, and do collaborative activities using a single shared video image. Utilizing these unique features of HyperMirror, we have implemented various interna- tional distance learning projects using HyperMirror between Japan and countries around the world for the past several years.
