The spread of social media has increased contacts of members of communities on the Internet. Members of these communities often use account names instead of real names. When they meet in the real world, they will find it useful to have a tool that enables them to associate the faces in front of them with the account names they know. This paper proposes a method that enables a person to identify the account name of the person (“target”) in front of him/her using a smartphone. The attendees to a meeting exchange their identifiers (i.e., the account name) and GPS information using smartphones. When the user points his/her smartphone towards a target, the target’s identifier is displayed near the target’s head on the camera screen using AR (augmented reality). The position where the identifier is displayed is calculated from the differences in longitude and latitude between the user and the target and the azimuth direction of the target from the user. The target is identified based on this information, the face detection coordinates, and the distance between the two. The proposed method has been implemented using Android terminals, and identification accuracy has been examined through experiments.
