Safety is paramount for construction industry throughout the world. Human errors which contribute to more than half of construction accidents, could be proactively prevented through effective education and training methods. Although Virtual Reality (VR) and Augmented Reality (AR) have gained much attention in various disciplines, few studies applied them for construction safety education. This research presents a new approach in construction safety education by utilizing VR and AR. The vision of aligning teaching & learning strategies is examined in order to ensure the potential benefits of the new method. This innovative approach shifts safety education from "Listen, and I will forget. See, and I may remember" towards "Practice, and I understand".

Recently, realistic contents such as virtual reality(VR) and augmented reality (AR) are widely used for education to provide beneficial learning environments with thee-dimensional(3D) information and interactive technology. Specially, AR technology will be helpful to intuitively understand by adding virtual objects registered in the real learning environment with effective ways. In this paper, we developed an AR learning system using 3D spatial information in the 2D based textbook for studying math related to geometry. In order to increase spatial learning effect, we applied to solid shapes such as prisms and pyramids in mathematics education process. Also, it allows participants to use various shapes and expression methods (e.g., wireframe mode) with interaction. We conducted the experiment with our AR system, evaluated achievement and interest. Our experimental study showed positive results, our results are expected to provide effective learning methods in various classes through realistic visualization and interaction methods.

This paper suggests the robust localization system in the application of ambient display with multiple ultrasonic range sensors. The ambient display provides the interactive image and video to improve the quality of life, especially for low mobility elders. Due to the limitation of indoor localization, this paper employs linear prediction algorithm to recover the missing information based on AR(Autoregressive) model by using Yule-Walker method. Numerous speculations from prediction error and computation load are considered to decide the optimal length of referred data and order. The results of these analyses demonstrate that the linear prediction algorithm with the 16th order and 50 reference data can improve reliability of the system in average 74.39% up to 97.97% to meet the performance of interactive system.

In the context of the 4th Industrial Revolution, IoT, Big Data, and VR are rapidly emerging as core sectors of future industries. In particular, the VR has been under the limelight as a new media content appealing to new generation. And the VR user is not merely a 'spectator', but the 'actor'. In other words, the newness of VR is not in the 'more likely representation of the virtual reality', but in the 'making it act more virtual (more technically, 'interactive')' in the virtual world. In this paper, we examine the VR cinema in terms of film composition unit, montage, cinematic space, mise-en-$sc{\grave{e}}ne$ and perspective. The VR cinema, which is in the early stage of evolution, is basically based on $360^{\circ}$ image that strengthens the autonomy of the audience's point of view, but other factors like haptic or sonic immersion are becoming increasingly important. In addition, the VR cinema will be combined with AR, MR, SR, and Interactive technologies, and will expand its horizon as it is produced in various forms. Therefore, it is expected that more detailed viewpoint will be applied in the subsequent study on VR cinema.

Biometric technology with the advance of deep learning enabled the new types of content. Especially, face recognition can provide immersion in terms of convenience and non-compulsiveness, but most commercial content has limitations that are limited to application areas. In this paper, we attempted to overcome these limitations, implement content that can utilize face recognition technology based on realtime video feed. We used Unity engine for high quality graphics, but performance degradation and frame drop occurred. To solve them, we augmented Dlib toolkit and adjusted the resolution image.

Super-realistic content technology has recently attracted attention as a core of the "new normal" that can overcome the spatial constraints caused by pandemics. It is moreover the core that allows users in remote locations to meet and engage in various social, cultural, and economic activities based on a network. Content technology is rapidly spreading beyond the existing entertainment area to various industries as an innovative tool that can be used to overcome space-time constraints and improve the productivity of industrial sites, because reality and virtual reality are now super-connected with ultra-low latency. However, existing services such as teleconferencing and tele-collaboration do not provide a level of realism that replaces face-to-face services, and various technical requirements have been proposed to overcome this. The trends in core technologies such as XR twins, hyper-realistic reproduction, sensory interaction, and emotional recognition technology, which are necessary for interactive realistic content that leads to feelings, from reproduction to experience and emotion, are explained. In this article, our aim is to present the future of realistic content that enables human care and can even overcome psychological difficulties such as the "Corona blues".

A hologram projects a 3 dimensional video as same as a real subject and it is made by principles of holography. Many researches about holographic technology have been developed. Studies for visualization of 3D videos, holographic storages, and optical media have proceeded mostly in engineering. It is hard to find any researches about the convergent system from the viewpoint of interactive elements and motion graphic design such as this paper's concept. Most studies of augmented reality have been developed in the domain of technology and education but the field of content production. AR has been convergent with various fields and media, so it is time to make an active progress in the study of convergent content development. The goal of this study is to develop cultural contents and create new values through the convergence of holography and AR. The purpose of this paper is to propose the way of developing the convergent type of cultural contents and construct the production system by the new approach to users using the convergence technology of holography and augmented reality.
