AR Room: Real-Time Framework of Camera Location and Interaction for Augmented Reality Services

Recently, as there has been increasing interest in augmented reality, relevant technologies are being developed in many fields. With the advance of camera-based technologies for augmented reality, new services are emerging. In this paper, we propose a new framework of augmented reality service application that multiple users can experience various contents respectively in the single space. To implement the proposed framework, we consider the structure which can share the view and data; such as device location, interaction and so on. This structure performs the following functions. In order to detect camera locations, we use the rear-facing camera of the device to estimate the position and pose. Estimated location information of all clients is sent to the server. The server synchronizes the location and interaction information of client based on point cloud map and broadcasts it to all clients. Using this information, users experience multiple contents interacting with other users in a single space while looking at the screen of the device. To demonstrate our framework, we build the AR service called “Winter Village” and show the performance of our framework.
