Introduction
Various tools have been designed to allow people to communicate from a distance. Some tools create ‘shared work spaces’ where participants can interact with each other doing various activities. One of these tools is HyperMirror.
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 international distance learning projects using HyperMirror between Japan and countries around the world for the past several years.
However, our projects also used other tools in addition to HyperMirror: standard video cameras, overhead cameras, and cameras showing a shared drawing space.
This paper provides information about our HyperMirror projects and the use of HyperMirror with other tools, and concludes looking at the role and effectiveness of HyperMirror and other tools for distance learning.
1 What’sHyperMirror?
Morikawa et al. (1998) designed HyperMirror which is a new video image communication tool. Unlike the traditional video conferencing system, HyperMirror uses composited video image with chroma-key effect (Figure 1). For this, HyperMirror allows local and remote participants to feel as if they are in the same room, share materials, and do collab- orative activities (eg. Figure 2). In addition, partici- pants can interact naturally because their own image is reversed and appears just as if they were looking in a mirror.
