본 논문에서는 개발한 가상현실 게임의 소개와 적용기술에 대하여 서술하였다. 가상현실(Virtual Reality, VR) 게임은 기존의 게임과는 다른 몰입도와 평면을 넘은 가상의 공간, 활동적인 액션의 이점을 가지고 있고 사람들과 같이 활동적인 플레이를 더하기 위해 다중사용자 환경의 기반을 구현하고, 좀 더 활동적인 다중사용자 환경으로 만들기 위해 서로 경쟁하는 사격게임과 같이 협력하여 플레이해 나가는 디펜스게임을 개발하였다. 개발도구로는 에픽 게임스의 언리얼 엔진4 v4.19.2을 개발엔진으로 활용하였고, HTC Vive의 VR장비와 컨트롤러를 사용하여 다중사용자를 위한 VR 게임 콘텐츠를 개발하였다.

VR기기를 착용하고 주변 시야가 차단된 상태로 일정 시간 사용하면, 다소 편차는 있지만 누구에게나 사이버 멀미 현상이 쉽게 일어날 수 있다는 문제점이 VR 관련 콘텐츠 개발자 및 사용자들에게 대두되고 있다. 이 문제를 현시점에서는 완전히 해결할 수는 없지만, 일반적으로 VR 게임을 개발할 때 사전에 숙지해야 할 중요한 부분 중 하나이다. 따라서 사용자가 VR 게임을 체험하기 전에 사이버 멀미를 예방하기 위해, 미리 개발 과정에서부터 사이버 멀미가 일어날 수 있는 변수를 최대한 줄이며 개발하는 여러 가지 방안에 대해 연구하였다. 본 논문에서는 먼저 고려해야 할 사항으로 사이버 멀미 현상이 일어나는 원인을 분석하고, 이를 예방할 수 있는 방법을 모색하여 상용 엔진인 Unity3D를 이용한 VR 게임 개발에 실제로 적용하였다.

The purpose of this paper is to identify the significance of heterogeneity in multi-player VR games. Heterogeneity is a concept of multi-player mode that a game uses the immersive VR and non-immersive system at the same time. As immersive VR device has become more commercial, multi-player VR games try to use heterogeneity strategically. is the best example to explain a new phenomenon, so this paper analyses by using a revised and reinforced MDA framework. As a result, we can find heterogeneity concept not only in the separation of player's interface, but also in the division of play patterns and experiences within a game itself.

Lately the VR (Virtual Reality) game genre is becoming increasingly more popular and it has been cementing its place in the market as its own independent game genre. The key advantage of VR is that it lowers the barrier between player and the virtual world, thus creating an immersive experience. The suggested method develops a game that allows the player to experience what it is like to be visually impaired using the unique characteristics of VR. A distinctive feature of this game is that the character is provided only a limited range of sight, which is created using silhouette outlines. This restrictive visual field is then grafted onto VR and the player can indirectly experience blindness in a highly immersive manner. The silhouette outline along with the particle system is created using Oculus Rift, a headset highly used in VR game development, and Unity 3D game engine. We will also explain in detail regarding the removal of borders between the objects.

With the technical development of fourth industrial revolution, VR game market is rapidly expanding. Meanwhile, heavy user group means the group consisting of people consuming certain media or contents more than others, which is the core constituency of the media industry, and there have been only a few studies on them. This study identified the factors that influenced the continuous intention of use of VR game heavy users and figured out their characteristics by verifying the difference in variables with the light user group. According to the results, the heavy user group showed higher behaviors than the light user group in terms of personal innovation, presence, and continuous intention of use variables. In addition to this, it was found that personal innovation, perceived quality, and presence had a significant influence on the continuous intention of use. This study is intended to empirically analyze the characteristics of heavy VR game users and influential factors, thereby preparing baseline data for VR game development and other relevant studies.

Good reviews that Half-Life: Alyx received created a turning point for the vitalization of the VR market with an uncertain future due to the absence of a revenue model together with the increased sales of VR equipment. Based on previous studies, this study categorized the characteristics of VR games according to graphs, first-person system, interface, controller, interaction technology, sound and stories. The analysis results show that the seven elements corresponded with "interactions" and "virtual images," which represent the completion level of games as part of VR components, and were connected to one another, which led to the proposal of an upper-rank concept "presence" to put them together. "Immersiveness," which represents users' emotions as part of VR components, was analyzed with the immersion theory to assign tasks of proper difficulty level for users' abilities. In the research process, the Delphi technique and FGI were administered to a panel of 15 experts to ensure objectivity. Finally, "presence" and "immersiveness" are characteristics in proportion to each other and can be valid concepts in future analysis of VR games as well as Half-Life: Alyx, which led to the proposal a new concept framework called 'presence effects' by combining the two words.

As virtual reality drew attention, VR room escape games were based on the most popular and successful VR content. This study was based on the survey results of citizens who experienced actual VR room escape and field-type room escape. It clarifies the parts that can be implemented and the parts that have technical limitations. And the factors that can increase the immersion of VR room escape games are analyzed. It is hoped that the significance of the research can contribute to the production of more advanced VR escape games and further VR contents.

This study aims to analyze the cases of VR space to improve the regulations. The space is divided according to the multi-use business act when the VR simulator and the VR game are simultaneously installed in a single space. It is necessary to amend the rules of the Tourism Promotion Act so that it can operate at a certain area of the youth game room subject to the Game Industry Law. Amendments that do not compartmentalize a space partition in the Multi-use Business Act should be carried out simultaneously. This is safer alternative by collective management rather than by the safety applied within a limited space by eliminating the compartment by industry. This is a legal amendment that allows VR simulator and VR game to be operated in the same space even in small sized amusement facilities such as other amusement facilities. This regulatory improvement plan is expected to help the activation of small sized VR theme parks.

본 연구는 신산업분야 특화 선도전문대학 지원사업 연구를 통해 개발된 CK-AR/VR PBL 교수법을 팀 프로젝트 기반의 캡스톤디자인 정규 교과목 수업에 적용해봄으로써, 해당 교수법의 장점 및 문제점을 파악하고 활용방안을 모색하기 위해 진행되었다. CK-AR/VR PBL 교수법은 기존 PBL(문제중심수업) 교수법의 특징과 장점을 유지하고 AR/VR 게임콘텐츠 특성에 맞는 특징을 중심으로 구축된 교수법으로 15주 정규교과목 수업인 '취업과창업을위한차세대게임창작프로젝트(캡스톤디자인)' 수업과 '취업과창업을위한차세대게임 포스트프로덕션(캡스톤디자인)' 수업을 수강한 200여 명의 학생에게 적용하였고 장단점을 파악하게 되었다. 이를 바탕으로 게임 개발 팀 프로젝트 교육과정을 운영 중인 교육 관계자들이나 앞으로 유사한 교육과정을 운영하기 위해 준비 중인 교육 관계자들에게 조금이나마 도움을 주고자 한다.

ICT 기술발전에 힘입어 게임은 짧은 시간 동안 기술적으로 큰 발전을 이뤄냈다. 최근에 들어서는 증강현실(AR;Augmented Reality), 가상현실(VR;Virtual Reality) 기술의 연구가 활발한데, 이는 사용자가 직접 게임의 가상공간에서 활동함으로써 독보적인 사용자경험을 제공할 수 있다는 점에서 차세대 게임 기술로 주목받고 있다. 그러나 AR VR 기술은 현재 상용화가 어려우며, 더 다양한 분야의 연구성과가 뒷받침되어야 비로소 구현이 가능하다는 점에서 근미래 게임기술의 목표로 삼기에는 부적합하다. 이에 반해 연관현실(Relative Reality) 플랫폼은 기술적인 요소의 비중이 큰 AR VR과는 다른 방법으로 현실과 가상현실을 엮어낸다. 연관현실은 현실에 가상현실을 더하는 AR과 현실에 기초한 가상현실을 구현하는 VR과 달리, 현실과 가상현실의 상호작용에 주목하고 있다. 이에 따라 연관현실 플랫폼은 기존 게임과는 차별화된 사용자경험을 제공하고, 현재의 기술 수준으로 지속가능한 개발이 가능하며, 향후 AR VR을 통한 대체현실 구현에 기여할 수 있다는 점에서 그 가치가 높다.
