Abstract: A virtual space control system sets a virtual space in a first virtual space, and expresses an embodiment space embodying a second virtual space in the virtual space. Virtual objects embodying embodiment target objects in the second virtual space are disposed in the virtual space. A disposition configuration of the virtual objects in the first virtual space is aligned with a disposition configuration of the embodiment target objects in the second virtual space, which are associated with the virtual objects. captured images serving as sources of embodiment images that undergo texture mapping onto the virtual objects are generated in a sub-server system. The embodiment images are created by causing the captured images to undergo calculation amount reduction processing.

Abstract: A computer system controls in parallel multiple virtual spaces that are set so as to have a common world view and that enables users to change their participation virtual spaces, manages occurrence incidents, which are incidents that occur or probably occur in each virtual space, and manages a target user's participation record for the first virtual space. Moreover, the computer system manages a restriction on target user's participation in a virtual space other than the first virtual space, based on (a) the difference between the first occurrence incident, which is an occurrence incident in the first virtual space, and an occurrence incident in the virtual space other than the first virtual space, and (b) the target user's participation record for the first virtual space.
