AR (Augmented Reality) on mobile device is beyond providing simple additional information. Moreover, it has extended its range to variety domains. The latest AR service for device recognition uses POI (Point of Interest), GPS (Global Positioning System) or digital compass. These technologies could not be applied well in home and office environments, because it is difficult to recognize small and uniform shaped devices like industrial products. Nowadays, other methods of device recognition have been widely studied. One is tracking device features. This makes feature model and then compares feature model with trained model. The other is that using bar code or RFID. Such methods are hard to get into user-space because dynamic device status, device sensing or recognition could not be made into trained model. Therefore, in inner space like home or office, AR has not been used widely compared to outer space. In this paper, we propose new concept of technology about device recognition using network profile information though a mobile camera interface. In addition, we provide preview method about device's service, contents, and real-time status information so that users can use faster, more intuitive user-interface in mobile devices. We implement the system of media server and renderer to share digital contents. This provides intuitive interaction for contents sharing just using camera preview.
