In order to solve these problems, we switch the HyperMirror image to the standard video camera image not composite and self image is not reversed For example, Figure 8 is the picture of a HyperMirror image that students were painting a pic- ture. As stated above, it is difficult for HyperMirror to zoom in participants and/or materials. By contrast, Figure 9 is the picture of a standard video camera image. Unlike the HyperMirror video image, the stan- dard video camera allows participants to focus on what they want to shoot. In other words, if partici pants want to show details of what they are working on, it is necessary to switch to the standard video camera image as necessary.
