The widespread use of smartphones has prompted the provision of a variety of services that exploit sensors installed in the smartphones, such as GPS, and augmented reality (AR). This paper proposes a method in which a user of such a smart terminal receives a message from a person passing by, and has the message displayed alongside the image of that person on the screen of the camera installed in the user's terminal. Specifically, the paper proposes a gravity center method that calculate the positions of the user and the passing person taking errors in the GPS measurements into consideration, and a method of displaying the message sent by the other person at a position on the camera screen calculated from the position data sent by the other person's terminal. These methods have been implemented in Android terminals, and the effectiveness of these methods has been evaluated.
