PROBLEM TO BE SOLVED: To visualize time of recording and storage and to facilitate window retrieval by setting time bases in arbitrary directions in a virtual space, deciding the time when each window is recorded and stored, and displaying the window on its corresponding time base. SOLUTION: A user moves in the virtual space by using a key board etc., and a virtual space moving means 2 retrieves a window displayed at a display part 14. A signal control part 6 converts signals obtained by the virtual space moving means 2, a three-dimensional position input means 1, and a window selecting means 3 into proper signals. An image processing part 11 generates images to be displayed in the virtual space and window on the basis of the signals obtained from the signal control part 6 according to data in an external storage device 10. Then a window display control part 9 sets time bases in arbitrary directions in the virtual space, decides the time when each window is recorded and stored, and displays the window on its corresponding time base at the display part 14. |
