Mobile AR Contents Production Technique for Long Distance Collaboration

This study proposes that mobile AR users with different physical spaces can use one collaboration coordinate by synchronizing each other's coordinates. When each user uses mobile AR remote contents from a distance, it is difficult to maintain the same working environment depending on their physical environment. In order for physical spaces to maintain the same working environment in different situations, the coordinates of the virtual object must be matched to the direction of each client. To solve this problem, this paper proposes a coordinate synchronization technology using a shared coordinate flag. Through this technique, the interaction of all subsequent objects can be performed based on the shared coordinate system of the local client. The user installs a coordinate synchronization flag on a map formed based on each physical space. Through this flag, the location of the virtual object may be synchronized based on each client to perform collaboration. To verify the proposed technology, the mobile AR remote technology was implemented as a painting contents application. Three users synchronized the coordinate system together on three Android mobile devices to verify the feasibility of the technology proposed in this paper.
