Design and implementation of a user-support system for finding the other person talking on smart phones

In this paper, we have designed and implemented a user-support system for finding the other person using smart phones. When users of this system talk over smart phones, it displays a map on the screen showing locations of both talkers as they share position information (GPS information) via a support server. Using this system, the user can check where to wait for other persons. It also enables the user to search for a lost child or to search for an illiterate person who wandered off and cannot return. In our system, the position of searchers is also displayed on the terminal of the person being searched for, therefore the child or illiterate person can check the searcher’s position on the screen of the smart phone in real time while talking.
