Abstract
Provided is a system and method for perceiving an outcast in a group. The system may include: a plurality of member terminals held, respectively, by a plurality of members conducting an outdoor activity and configured to transmit waves with a radio frequency; and a leader terminal held by a leader of the outdoor activity and configured to receive the waves transmitted from the plurality of member terminals, to sense intensities of the waves, to obtain distances between the plurality of member terminals from the sensed intensities of the waves, to calculate a group distance based on the obtained distances between the member terminals, to sort the plurality of member terminals into at least one subgroup, and to determine an outcast member terminal excluded from the at least one subgroup.
