A view image rendering module (102) generates an image of a virtual space
on the basis of a first viewpoint indicating the viewpoint of a user on
the virtual space, and displays the generated image on a view image
presentation module (101). A map image rendering module (104) generates a
map image indicating a region around the position of the first viewpoint
on the virtual space, and displays the generated map image on a map image
presentation module (103). The position of the first viewpoint and the
visual axis direction are controlled using a viewpoint
position.cndot.visual axis direction input module (106) which is provided
on the display surface of the map image presentation module (103).
Furthermore, a virtual object set on the virtual space undergoes
manipulation control using a virtual object manipulation input module
(107) which is provided on the display surface of the map image
presentation module (103).
