Abstract There is provided a communication apparatus for exchanging messages while a virtual space and avatars (symbols) of users are displayed on a display screen. The communication apparatus has a viewpoint element inputting unit for inputting a viewpoint element (a viewpoint position and a viewpoint direction). An image of the virtual space is produced on the basis of the viewpoint element inputted from the viewpoint element inputting unit. According to the communication apparatus, it is possible to increase a degree of freedom in plotting the virtual space.
