7. The method according to claim 1 , further comprising:

replaying another event associated with a second virtual space recorded at the first point-in-time, in response to receiving a user input selecting a graphical object associated with a movement to the second virtual space during the replaying of the first event, the another event including the second virtual space recorded at the first point-in-time and motion data for another set of avatars in the second virtual space.

8. The method according to claim 7 , further comprising:

determining whether the user has user rights associated with switching between virtual spaces; and

activating the graphical object associated with the movement to the second virtual space, in response to the user input selecting the graphical object associated with the movement to the second virtual space during the replaying of the first event, if the user has the user rights associated with switching between the virtual spaces.

9. The method according to claim 1 , further comprising:

initiating recording of the first virtual space and motion data of a set of avatars in the first virtual space, in response to receiving a user input selecting a graphical object associated with an event recording.

10. The method according to claim 9 , further comprising:

determining whether the user has user rights associated with the event recording; and

activating the graphical object associated with the event recording, only if the user has the user rights associated with the event recording.

11. A non-transitory computer-readable recording medium storing instructions that, when executed by one or more processors, cause performance of the method according to claim 1 .

12. A method of displaying a virtual space at various point-in-times using one or more processors of a user terminal, the method comprising:

displaying a user's avatar on a first virtual space;

displaying a user interface including a plurality of point-in-time information associated with the first virtual space, in response to receiving a first user input selecting a first graphical object associated with a movement between the various point-in-times;

receiving, from a user, a selection of a first point-in-time from among the plurality of point-in-time information;

replaying a first event associated with the first virtual space recorded at the first point-in-time, the first event including the first virtual space recorded at the first point-in-time and motion data for a first set of avatars in the first virtual space,

receiving, from the user, a selection of a second point-in-time from among the plurality of point-in-time information associated with the first virtual space; and

displaying a second set of avatars associated with an expected participant at the second point-in-time, on the first virtual space associated with the second point-in-time, and

wherein the second point-in-time is associated with a scheduled second event scheduled to occur after a current point-in-time, and the displaying the user interface comprises:

displaying, on the user interface, date information of the second point-in-time and a second set of keywords associated with the scheduled second event.

13. A user terminal, comprising:

a communication device;

a memory; and

one or more processors connected to at least the memory, the one or more processors configured to execute one or more computer-readable programs included in the memory to configure the user terminal to display a virtual space at various point-in-times by,

displaying a user's avatar on a first virtual space,

displaying a user interface including a plurality of point-in-time information associated with the first virtual space, in response to receiving a first user input selecting a first graphical object associated with a movement between the various point-in-times,

receiving, from a user, a selection of a first point-in-time from among the plurality of point-in-time information, and

replaying a first event associated with the first virtual space recorded at the first point-in-time, the first event including the first virtual space recorded at the first point-in-time and motion data for a first set of avatars in the first virtual space,

wherein the first point-in-time is a past point-in-time occurring prior to a current point-in-time, and

the replaying comprises:

replaying the first event such that the first virtual space includes therein date information of the first point-in-time and a first set of keywords associated with the first virtual space at the first point-in-time, and

wherein the one or more processors are configured to execute the one or more computer-readable programs to further configure the user terminal to,

extract the first set of keywords from one or more of voice data or text data included in a first set of the motion data in the first virtual space recorded at the first point-in-time.

14. The user terminal according to claim 13 , wherein the one or more processors are configured to execute the one or more computer-readable programs to further configure the user terminal to,

receive, from the user, a selection of a second point-in-time from among the plurality of point-in-time information associated with the first virtual space, and

display a second set of avatars associated with an expected participant at the second point-in-time, on the first virtual space associated with the second point-in-time.

15. The user terminal according to claim 14 , wherein the second point-in-time is associated with a scheduled second event scheduled to occur after a current point-in-time, and

the user interface is configured to display date information of the second point-in-time and a second set of keywords associated with the scheduled second event.

16. The user terminal according to claim 13 , wherein the one or more processors are configured to execute the one or more computer-readable programs to further configure the user terminal to,

replay another event associated with a second virtual space recorded at the first point-in-time, in response to receiving a user input selecting a graphical object associated with a movement to the second virtual space during the replaying of the first event, the another event including the second virtual space recorded at the first point-in-time and motion data for another set of avatars in the second virtual space.

17. The user terminal according to claim 13 , wherein the one or more processors are configured to execute the one or more computer-readable programs to further configure the user terminal to,
