Teleconference is to connect two or more remote places by interactive telecommunication technology, and hold the meeting with a bidirectional picture and sound. It is also a kind of groupware. The advantage of a teleconference is that travel time and cost can be held down. It is not necessary to prepare the place of a meeting and to go to a conference hall place. It is only to connecting to television. Moreover, unlike an ordinary telephone, since the teleconference can see a mutual face and speak, it can aim at deep communication. However, there are a little problems here. It is known that eye contact is important in conversation. Although a partner’s face cannot be seen by ordinary telephone, since a face can be seen, the wrong impression may be given at a teleconference. Research which combines the picture of the right look with a stereo system in order to cope with this problem is advanced.

Projecting the images taken by the camera

The image taken by the digital camera and video camera can be projected on television, and can be seen. By projecting on television, a still picture and an animation can be seen in big screen rather than seeing with the camera itself. And by seeing by a big screen, it can see together with many persons. It is recommended projecting on television to see animation, such as a children’s exhibition and an athletic meet, with all families.
