For example, Figure 8 is the picture of a HyperMirror image that students were painting a picture. 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 standard video camera allows participants to focus on what they want to shoot. In other words, if participants want to show details of what they are working on, it is necessary to switch to the standard video camera image as necessary As shown in Figure 10, the picture illustrates another way of use of a standard video camera image. The picture shows students in Thailand who participated in distance learning and did their work--whole of classroom. Thus, in case of showing details of students working on a task and a scene of the classroom, we switched HyperMirror to the standard video camera image.
