Method and apparatus for preventing separation of accompanying persons
First Claim
1. A method for preventing separation of accompanying persons using a first apparatus and a second apparatus connected through a short-range wireless communication network, comprising the steps of:
- calculating, by the first and second apparatuses, self-locations of the first and second apparatuses;
exchanging, by the first and second apparatuses, the self-locations with each other;
calculating a distance between the first and second apparatuses using the self-locations;
outputting, if the distance between the first and second apparatuses exceeds a pre-set distance, an alarm warning of separation state and designating current locations of the first and second apparatuses as absolute locations;
detecting travel routes from the absolute locations of the first and second apparatuses;
exchanging the detected travel routes; and
displaying, by the first and second apparatuses, travel routes of counterparts.

Abstract
Disclosed herein are a method and apparatus for preventing separation of accompanying persons by using a first apparatus and a second apparatus connected through a short-range wireless communication network. The method includes: calculating self-locations of the first and second apparatuses; exchanging the self-locations with each other; calculating a distance between the first and second apparatuses using the self-locations; outputting, if the distance between the first and second apparatuses exceeds a pre-set distance, an alarm for warning a separation state and designating current locations of the first and second apparatuses as absolute locations; detecting self-travel routes from the absolute locations of the first and second apparatuses; exchanging the detected self-travel routes with each other; and displaying the travel routes of counterparts.

12. An apparatus for preventing separation of accompanying persons comprising a first apparatus and a second apparatus connected through a short-range wireless communication network,
wherein the first and second apparatus each comprise: -
a short-range communication network interface for transmitting/receiving data through the short-range wireless communication network; a location data input unit for inputting location data; a self-location calculator for calculating self-locations using the location data; a travel route detector for detecting travel routes of the first and second apparatuses using the location data; a distance calculator for calculating distance from a counterpart using a location of the counterpart first or second apparatus transmitted through the short-range communication network interface and the calculated self-location; a controller for, if the distance calculated by the distance calculator exceeds a pre-set distance, controlling the travel route detector to detect a travel route of the apparatus by designating a current location of the apparatus as an absolute location and controlling the short-range communication network interface to exchange the detected travel route with the counterpart; and a display unit for displaying a travel route of the counterpart transmitted through the short-range communication network interface. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
