  • Immersive media, also known as spatial media, has become essential with the decrease in face-to-face activities in the COVID-19 pandemic era. Teleconference, metaverse, and digital twin have been developed with high expectations as immersive media services, and the demand for hyper-realistic media is increasing. Under these circumstances, MPEG-I Immersive Media is being standardized as a technologies of navigable virtual reality, which is expected to be launched in the first half of 2024, and the Audio Group is working to standardize the immersive audio technology. Following this trend, this article introduces the trend in MPEG-I immersive audio standardization. Further, it describes the features of the immersive audio rendering technology, focusing on the structure and function of the RM0 base technology, which was chosen after evaluating all the technologies proposed in the January 2022 "MPEG Audio Meeting."

  • The Republic of Korea (ROK) Army is developing the Army Synthetic Battlefield Training System and plans divisional-level Live, Virtual, and Constructive (LVC) integrated training. This study proposes a plan to apply VR/AR/MR (Virtual Reality/Augmented Reality/Mixed Reality) technology to LVC integrated training systems to enhance the efficiency and effectiveness of future LVC integrated training. The study investigated immersive military training systems in the ROK and advanced countries. As a result, we confirm that immersive technology can significantly improve the efficiency and effectiveness of military training. Accordingly, we review the key technologies required for building a defense training system with immersive features and propose training subjects that can be enhanced in effectiveness and efficiency when built with an immersive approach. We also propose a plan to apply immersive technology to the Live, Virtual, and Constructive systems for the development of future LVC integrated training system.

  • The aim of this study was to examine the trends (e.g., the distribution of the studies by year, country, research methods, and participants' education level) and fundamental findings [e.g., interaction in Virtual Reality (VR) environments, educational content through VR and Augmented Reality (AR) technologies, learning environment in AR, etc.] regarding immersive learning technologies such as VR and AR in English Language Teaching (ELT) between 2010 and 2019. Employing a systematic review research methodology, data was gathered from 59 academic articles published in the following databases: EBSCOhost, ERIC, Web of Science, and Taylor & Francis. The studies were analyzed using a content analysis approach, and findings demonstrated that immersive learning technologies in ELT came to prominence in 2017. Mixed methods research was the most widely employed research method. The most studied language skill was vocabulary for AR and speaking for VR. The results also revealed advantages and challenges with regards to the use of immersive learning technologies in ELT. Further analysis illustrated the findings related to characteristics of immersive learning technologies in ELT. Based on this review, research and design implications for researchers and practitioners are presented.

  • The purpose of this study is to investigate the potential of immersive environments in the design domain by analyzing students' design process in immersive environments from cognitive and experiential aspects. To do this, we reviewed major concepts and theories such as users' immersion, participation, presence, and awareness and developed a comprehensive conceptual framework of immersive shared environments. In three different visualization systems of HIVE, teams consisting two students were assigned to design tasks and the design process was analyzed by a customized framework. The characteristics of the immersive environment related to the performance of the design task were different from those of the previous studies. The perception of the relationship between the spaces is very important, and the perception of the surrounding objects is interested in the shape or the material such as whether the object is flat or inclined. Also, it is found that the multi-technology of immersive environments is very useful for creative collaboration. In the future, a more comprehensive analysis of the effects on design decisions in a more diverse visual interface condition and the effects on more diverse design areas should be added.

  • Virtual reality is being increasingly used for healing and therapy for mental health. In this study, we developed VR-based immersive content that enables virtual travel without the limitations of time and physical conditions. We aim to develop and produce VR content for relaxation and meditation using the beautiful natural scenery. To make realistic and immersive content, we took a video of natural sceneries with a small UAV connected to a VR camera. The content was developed through stitching, video editing and post-processing of the initially captured video data, and then the created VR video was inserted into the VR device. The produced content will be helpful for stress and used to heal the mind and body of exhausted modern people by providing the place with great scenery and sound in an immersive way at any time.

  • The research on the immersive media technology is actively being done with the emergence of immersive services using immersive media, especially in the broadcasting industry and with the increased market demand for it. The industry which produces, transmits, processes and services the immersive contents is commonly called Immersive Media Industry. Immersive Media Industry has recently received attention as next-generation strategic industry with its high marketability and its high possibility of market expansion through convergence with other industry such as education, health, advertisement, travel and public service industry. As other advanccd country such as the U.S., Japan and Europe buckle down to take the innitiative in the immersive media industry, Korea government also begins to make plan to promote the immersive media industry.

  • The market size of immersive 360-degree video contents, which are noted as one of the main technology of the fourth industry, increases every year. However, since most of the images are distributed through illegal distribution networks such as Torrent after the DRM gets lifted, the damage caused by illegal copying is also increasing. Although filtering technology is used as a technology to respond to these issues in 2D videos, most of those filtering technology has issues in that it has to overcome the technical limitation such as huge feature-point data volume and the related processing capacity due to ultra high resolution such as 4K UHD or higher in order to apply the existing technology to immersive 360° videos. To solve these problems, this paper proposes a feature-point recognition ratio improvement method for immersive 360-degree videos using deep learning technology.

  • Although virtual reality technology may not be deemed as having a satisfactory quality for all users, it tends to incite interest because of the expectation that the technology can allow one to experience something that they may never experience in real life. The most important aspect of this indirect experience is the provision of immersive 3D audio and video, which interacts naturally with every action of the user. The immersive audio faithfully reproduces an acoustic scene in a space corresponding to the position and movement of the listener, and this technology is also called spatial audio. In this paper, we briefly introduce the trend of spatial audio technology in view of acquisition, analysis, reproduction, and the concept of MPEG-I audio standard technology, which is being promoted for spatial audio services.
