<p><P>PROBLEM TO BE SOLVED: To provide pleasant and efficient operability which temporarily stops a view point follow-up function and smoothly restores the visual field to a state immediately prior to the stop, when the function is reopened, in a virtual reality generation system. <P>SOLUTION: In the virtual reality generation system, a request for stopping and reopening a view point follow-up operation is made by a controller 106, and when the request for stopping the view point follow-up operation is made, the state of a user's view point which is detected by means of a receiver 102 is stored and laid in a restoration view point status. Then, the view point follow-up operation is stopped, and the receiver 102 continues to monitor the state of the user's view point after the view point follow-up operation is reopened, and then the view point follow-up operation is reopened for the first time when the present status of the user's view point comes nearly to the restoration view point status. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
