Method and apparatus for preventing separation of accompanying persons |
摘要 |
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.
