Abstract: A method for mediating uses of smart devices of group users includes creating a location-based virtual self-control space, searching for a virtual self-control space that is adjacent to a smart device of a requester for mediating uses of the smart devices of the group users, from the created virtual self-control space, selecting an interest space which the requester is to participate in, from the found virtual self-control space, and allowing smart devices of group users pertaining to the interest space to participate in self-control of use, allowing the smart devices of the group users to apply a use restraining mode in the virtual self-control space corresponding to the interest space, and after applying the use restraining mode, allowing the smart devices of the group users to release the use restraining mode in the virtual self-control space corresponding to the interest space.
