This study aims to explore the problems of the VR content industry, which is the core of the newly emerging fourth industrial revolution and convergence new industry, and to find alternatives to solve them. Through in-depth interviews with experts, we collected elements that impeded the development of VR content industry. As a result, the simplification of the VR simulator's content changes, the regulation of the VR simulator was newly established within the Game Industry Act, and the diversification of the input amount were the reasons. Simplification of deliberation provides the basis for new platform business. The new law is to reflect the characteristics of VR content properly and to avoid unnecessary regulation by existing laws. The adoption of various input methods is intended to actively expand the market for new industries. This study is expected to contribute the safe ecosystem by reviewing the factors that impede the development of the new industry as suggesting alternatives.

This paper proposed a method which enabled the designing and implementation of a serious game based on AVR microcontroller on a virtual serial port before making the actual circuit by performing simulation, and which made it possible to develop a serious game. The implemented serious game implemented a mole game which can be enjoyed by one person, a love game with which a male gamer and a female gamer can play, and a marathon game in which a gamer can run the marathon while listening to cheerful music and looking at a region he/she wants to visit. The development of a microcontroller device that provides those functions showed that not only does the device make it possible to develop games more easily and conveniently through the implementation of a game using virtual serial communications with a board designed by an ISIS simulator, but also it reduces trials and errors during game development.

A simulation game represented the real world and situation as a video games, In the first time, this simulation game primarily applied to military practice areas and then it's applied areas were extended to strategy, flighting, racing, life areas. In this paper, we developed the driving simulator that operate the 3-axis sensor attached driver's handle which could forward/backward moving, control of direction, and transmit of gear in the virtual space. For more the realities of the situation and accuracy of the location and speed, we adopted the 3-axis sensing informations, Unreal engine4' and Blueprint.

자율주행 시뮬레이터를 위한 대체재로 게임 엔진을 통한 가상 환경 모의 연구가 수행되고 있다. 하지만 게임 엔진에서는 자율 주행에 필요한 센서를 기기에 맞게 사용자가 직접 모델링을 해줘야 하기 때문에 개발 비용이 크게 작용된다. 특히, Ray 를 활용한 3D LIDAR 는 GPU(Graphics Processing Unit) 사용량이 많은 작업이기 때문에 저비용 시뮬레이터를 위해서는 저비용 3D LIDAR 모의가 필요하다. 본 논문에서는 낮은 컴퓨터 연산을 사용하는 C++ 기반 3D LIDAR 모의 프레임 워크를 제안한다. 제안된 3D LIDAR 는 다수의 언덕으로 이루어진 비포장 Map 에서 성능을 검증 하였으며, 성능 검증을 의해 본 논문에서 생성된 3D LIDAR 로 간단한 LPP(Local Path Planning) 생성 방법도 소개한다. 제안된 3D LIDAR 프레임 워크는 저비용 실시간 모의가 필요한 자율 주행 분야에 적극 활용되길 바란다.

3D modeling and rendering technologies are getting more attention from landscape planners and architects because the virtual reality based on 3D graphic technology could give more realistic experience to landscape simulation users and boost promotional effects. The 3D landscape simulation, however, not only requires a lot of cost and time in production, but also demands efforts to distribute to consumers due to various computing environment of them. The purpose of this study is to suggest a process for developing an interactive 3D landscape simulator with low-cost, which can support multi-platform functionality in high quality through reviewing related current software and web services. We select GIMP for 2D image texturing, SketchUpfor 3D modeling, Unity for real-time rendering, and Google Earth for terrain modeling considering price and workability and apply the developed process for Windows, Web, and Android versions to test the applicability for Sangji-ri, Gosam-myeon, Gyeonggi-do, Korea.

Some innovative researchers have had a dream of self-thinking intelligent computer. Alphago, at last, showed its possibility. With it, most computer engineers including even students can learn easily how to do it. As the interest to the deep learning has been growing, people's expectation is also naturally growing. In this research, we tried to enhance the game ability of a 7-poker system by applying machine learning techniques. In addition, we also tried to apply emotion analysis of a player to trace ones emotional changes. Methods and outcomes are to be explained in this paper.

The purpose of this study is to investigate the problems of the VR simulator industry represented by the 4th industrial revolution and to examine measures for industrial promotion. For this purpose, we consider the VR simulator regulation and examine the problems. Since the VR simulator has the features of existing arcade games and amusement facilities, it should be classified as game or inspected with amusement facilities depending on the viewpoint. This can be a dual regulation, and before the VR simulator industry starts, there is a risk that the industry itself can be damaged by existing legal limitations. For this purpose, it is necessary to provide a unique legal system for VR simulator and it is necessary to examine the contents to be included in such laws and systems. It is expected that the legal system of VR simulator will lead to promotion of new industry.

This research was conducted to explore relationships among situation awareness, presence, and performance on a handheld game console. Situation Awareness was measured by SAGAT (Situation Awareness Global Assessment Technique) while presence was measured by PQ (Presence Questionnaire) version 3.0. The performance was measured by the number of aircraft shot down during the flight simulator game. The results show that both situation awareness and presence were positively significantly correlated with performance. In order to investigate the effect of performance level, subjects were divided into two significantly different groups: low and high performance groups. In the low performance group, both situation awareness and presence showed a significantly positive correlation with performance. The correlation between presence and situation awareness also showed a positively significant correlation. However, in the high performance group, there were no significant correlations among them. In conclusion, different performance levels could be said to be an important factor in the study of situation awareness and presence. Furthermore, this study also proved that the domain of research on situation awareness and presence was extended to small displays such as the handheld game console.

Korea DM&S(Defence Modeling & Simulation) development plan includes construction of a distributed simulation model which enables us to construct, operate, integrate and connect war game simulations. US DoD and IEEE set the HLA/RTI as the standard of distributed simulation model. HLA/RTI models each simulator as a Federate and group of them as a Federation. Simulation with the model shows interoperability and finally executes a war game simulation. Because of different resolutions and features, it is not satisfied 'interoperability' and 'reusability' of simulation perfectly MRM (Multi Resolution Modeling) has been introduced, and many developed countries including the United States have studied the technology to simulate the model with different resolutions. This thesis proposes the need for introduction of MRM and analyzes both technical and operational validity when we apply MRM model to army war game simulations. For these purposes, we 1) find MRM main issues with the study about MRM basic concepts and case studies of MRM's applications, 2) present the need of MRM and its relation with DM&S development plan, and 3) analyze its technical and operational validity when we apply MRM to an example, CHANG-JO21 and JEON-TOO21.
