AR Telecommunication

Abstract

• The main contribution of this paper is to examine the new method of augmented reality from a telecommunication point of view. Then, we tried to present the fact that the concept of social presence is an important cue for developing telecommunication system based on augmented reality technology. The evaluation was conducted with 32 participants. According to the questionnaires results, the augmented reality based telecommunication system was better than 2 dimensional based display telecommunication system. To develop our concept, we should closely analyze communication patterns and improve our augmented reality based communication system.

DigiLog Space: Real-time Dual Space Registration and Dynamic Information Visualization

Abstract

• • 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
