Abstract:
Disclosed herein is a system and method that analyze a plurality of types of interactions between devices and between users, predict intimacies therebetween, find small groups within a certain group based on the intimacies, and then detect outcasts. The system for detecting a small group and an outcast includes a data collection unit for collecting data based on interactions between objects. A data analysis unit analyzes the data. An intimacy prediction unit calculates intimacies between objects based on the analyzed data. A small group configuration unit detects one or more small groups from a certain group, based on the calculated intimacies. An outcast detection unit detects an outcast, based on presence or absence of each object in the one or more small groups and the intimacies.
Abstract:
Disclosed herein is an apparatus and method for recognizing a nearby device, which measure distances between devices and calculate intimacies between the devices, thus notifying a user of the distances to and intimacies with nearby devices. The apparatus includes a distance determination module unit for determining distances to a plurality of nearby devices based on signals for distance determination, received from the respective nearby devices. A zone determination module unit determines zones to which the respective nearby devices belong, among multiple zones, depending on the distances to the respective nearby devices. A nearby device recognition module unit recognizes the nearby devices using received information of the nearby devices. An intimacy determination module unit determines intimacies with the nearby devices, based on previously stored information required for intimacy determination. A user interface unit displays results of distance determination and intimacy determination to a user.
