In this paper, we propose a DigiLog space that combines physical real world and its mirrored world to realize a 4D+ augmented reality. To support this, a RGB-D-based feature map is designed which is robust to lighting changes and enables texture-less object detection and tracking. Then we suggest a real-time context of interest(CoI) registration method for dynamic augmented reality(AR) information visualization. Through these technologies, a user wearing AR glasses can seamlessly experience CoI-based AR information of the 4D+ mirror world while moving indoors or outdoors. Therefore, a human's activity can be spatially/temporally extended by sharing and experiencing the mirror world’s useful information.
This could be applicable to AR-based time/space-transcended smart work, next-generation experimental education, AR simulation, video-based information surveying, AR medical information, and AR entertainment.
