Abstract: A method of controlling users in a multi-user virtual space and a system for controlling users in a multi-user virtual space. The method includes the steps of: a) connecting lines formed by vertically and equally dividing lines obtained by connecting fixed points, which are center points of fixed objects in a three-dimensional virtual space, to partition the space into sub-spaces; b) calculating the distance between the position of a new user and fixed points of each partitioned sub-space and distributing the new user to the partitioned sub-space having the shortest distance; c) checking and controlling positions, movement and rotation information of each user; and d) repeatedly checking whether there is a new user, and repeating steps b) and c) when there is a new user. Accordingly, the three-dimensional virtual space is partitioned around a fixed point irregularly arranged in the virtual space, and users are assigned to a sub-space and a server according to the distance between the fixed point and the user.
