Purpose: The purpose of this study is to investigate how the type of virtual reality content production affects the interaction and immersion that is a virtual reality characteristic, and to provide the platform companies and content producers with the basic information necessary to provide the production and service of content suitable for VR characteristics. Methods: Based on the data collected in the survey, multiple regression analysis and hierarchical regression analysis were used. The measurement tools used in this study were studied through three-dimensional composition, including the characteristics and interaction and immersion of content produced in 2D, 3D and 360°, which are elements of virtual reality characteristics. Results: The results of this study are as follows. Among the types of content production, content produced with 2D and 360 technologies was found to affect immersion, while content produced in 3D affected interaction. Motion sickness has been investigated to affect both immersion and interaction. Conclusion: Service-provided platform enterprises and content-making enterprises should consider content-making and providing services that suit service characteristics and purposes, taking into account the characteristics of interaction and immersion in content-making investment and service delivery.

In this paper, we present a design evaluation system with visualization and interaction of mobile devices using virtual-reality-based prototypes which can be used to easily change design parameters and simulate embedded software. To evaluate and predict affective-engineering-based design preferences for mobile devices under a virtual environment, we have developed a high quality visualization platform which creates images that look similar to real mobile devices in addition to real-time simulation of realistic motions and functions of mobile devices. To support a quantitative usability test scenario for external design shape, we also have built a system which consists of a mixed-reality-based testing platform for measuring hand load.

This year, global IT companies such as Google, Apple, and Facebook launched a mobile augmented reality platform. Existing augmented reality technology required a special device such as AR glass or tango phone, but now it will be easy to experience augmented reality in general Android phone and iPhone. The mobile augmented reality game market, which has been attracting interest since the Pokemon game, is expected to become more active. In this article, we introduce augmented reality platforms technology for mobile augmented reality game and mobile augmented reality games including ETRI prototype centered on user interface.

Recent advances in augmented reality (AR) and virtual reality (VR) technologies have led to a significant increase in metaverse platforms. Metaverses are setting a new direction for the digital world. This paper examines the phenomenon of virtual worlds that are becoming an issue these days, focusing on [Ready Player One]. One of the common features of the metaverse platform in [Ready Player One] and the platforms currently in use is the concept of open world. This is a feature that goes beyond simply moving around in a virtual world and allows users to freely reset, participate in, and control the environment. This innovative concept is a hallmark of metaverse platforms, and it is becoming increasingly important and influential. Through this study, we focused on the [open world system] of the platform in the movie and the modern metaverse platform, and suggested and studied how the scalability of the metaverse will present a turning point in the future.

This study proposes suitable input processing technique for producing the mobile platform based virtual reality contents. First of all, we produce the mobile platform based virtual reality interactive contents to be used in experiments for improve user's immersion who experience the virtual reality contents, get interests and design the input processing that easily controllable. Then design the input processing technique in two methods, with gamepad that accessibility to mobile and with directly through user's gaze to interface. Through virtual reality based input processing technique that we proposed, we analyse effect of improve user's immersion, cause of get interests and whether provide the convenience or not for controlling contents through experiments. Moreover we verify whether bring negative psychological elements like sickness, fatigue or not.

This paper tried to study how the narrative to allow the audience to emotionally immerse in documentary using virtual reality platform has shown. For this purpose, it defined the VR documentary as contents what make creative approach and rebuild reality using VR media platform, and analyzed it by comparison with narrative of existing documentary. First, the contents like succeeding journey documentary use mainly virtual realty as experience of accessibility. However the contents that have purpose to experience other people's reality show from self-narrative of first person documentary to interactive storytelling of web interactive documentary. The case of interactive VR documentary is taking a step forward from web documentary and shows easy way to reach internal purpose of documentary as making experience with virtual self. The VR documentary has a lot of possibility as virtual space experience to give accessibility and virtual self.

We implemented virtual reality training system for city gas virtual training platform using oculus $rift^{TM}$, gear $VR^{TM}$ and dome screen. And we carry out a survey targeting ordinary person using each device. The contents of survey are usability and reality about each training system and the goal of survey is a verification how to bring effectiveness using city gas governor safety training system. The survey method used each VR device for the ordinary person and investigated the difference. Based on the survey it was to find out the direction for the implementation of platform, could find out the possibility of a virtual training system.

The research of combining virtual reality technology with the design elements of children's picture book education is a relatively new topic in virtual reality technology in recent years. Based on the combination of picture book design elements with virtual reality technology and the development of a children's picture book teaching game, this article analyzes the effectiveness of the application of virtual reality technology in children's teaching, and explores the usability of picture book design elements in teaching [1]. Through literature research methods, practical research methods and investigation research methods, this paper lucubrates the application of virtual reality technology in the design elements of children's picture book education so as to provide adequate theoretical and practical support for the research theme. The spatial positioning, vision, sound, and functional requirements of children's picture book games play a leading role in teaching. Practical statistics have proved that it is easier to promote children's mastery of teaching knowledge in a virtual environment. Moreover, use VR's game management function and setting function to solve the boringness of traditional education methods and the limitations of the teaching environment. The feasibility of game operation provides a virtual teaching platform system for children's education, and the teaching effect is remarkable.
