  • Virtual reality (VR) technology has been increasingly more frequently used day by day in industries, entertainment and performances due to the development of AR and MR technologies. Performance arts also actively utilize $360^{\circ}$ VR technology due to the free expression of stage settings and auditoriums. However, technologies for systems in which performers wear VR devices firsthand rather than being in the sandpoint of bystanders while audiences wear VR head mounted displays(HMDs) to see performance stages have been rarely studied yet. This study investigated the technical possibilities of possible methods of expression that will enable performers to appear on the stage wearing VR devices. Since VR can maximize the sense of immersion with its closed HMD structure unlike augmented reality (AR), VR was judged to be suitable for studies centered on the mental interactions in the inner side of humans. Among them, to implement shamanistic expression methods with the phantoms of the body and soul, a motion capture technology linked with VR display devices and real-time cameras was realized on the stage. In this process, the importance of body ownership experienced by the performers (participants), reactions when they lost it, and the mental phenomena of the desire to possess the subjects of gaze could be seen. In addition, high possibility of development of this technology hereafter could be expected because this technology includes the technical openness that enables the audience to appear on the stage firsthand to become performers.

  • The motion base to a film used in 4D cinema theaters or theme parks is different depending on the operator's control or hardware system and this causes inefficiency in management of the theater. There are several different simulation software on the present market, but these are difficult for an animation producer to use them. This study introduces the idea in which a film producer simulates the movement of the motion base by using computer graphic animation tools mostly adopted by production for creating 3D animation and motion control data. Maya and 3D Cross were used to show the path of a motion camera visually. Attitude and axis control data were extracted from the movement of the virtual motion base and were used to control a prototype of the motion base. As a result, the motion control data from computer graphic animation tools can be created so that a film producer can create standard motion control data independently regardless of the hardware and operator's skill.

  • 국방 시뮬레이션 유형은 워게임 모형으로 분류되는 Constructive 시뮬레이션, 실 기동에 의한 Live 시뮬레이션, 그리고 가상현실을 적용한 Virtual 시뮬레이션 등 3가지로 분류될 수 있다. 워게임 시뮬레이션은 일반적으로 대부대 훈련에 적합하지만 많은 가정사항을 내포하게 됨으로써 현실감이 떨어지고 실 기동 시뮬레이션은 실전적인 훈련이 가능하지만 전구급 수준의 대부대 훈련에의 적용이 곤란한 단점이 있다. 또한 이들 시뮬레이션 유형들은 개별적으로 운용됨으로써 각 유형들이 가지고 있는 취약점이 노출되고 있는 현실이다. STOW(합성전장 훈련체계, Synthetic Theater of War)는 실제훈련이 가능한 분야는 실 기동으로, 실 훈련이 불가능한 전장상황은 시뮬레이션 기법을 활용하여 상호결합 시킴으로써 각 시뮬레이션 유형들의 제한사항을 상호 보완하여 실제와 유사한 전장을 조성하여 훈련하는 종합적이고 체계적인 훈련체계로써 21세기에 예상되는 전쟁이외의 작전(OOTW), 비대칭전, 정밀타격 및 C4I를 모의할 수 있는 엔티티 수준의 합성전장이다. 본 고는 STOW의 구성요소(합성부대, 합성환경, 시뮬레이션 네트워크, 지형 DB 개발도구, C4I 인터페이스, 기반체계 등)를 국내기술 능력과 비교, 분석함으로써 우리의 여건에 적합한 STOW 체계 구축방안을 제시하고자 한다.

  • In this study, we apply the facial Facial Action Coding System for coding the muscular system anatomical approach facial expressions to be displayed in response to a change in sensitivity. To verify by applying the virtual character the Duchenne smile to the original. I extracted the Duchenne smile by inducing experiment of emotion (man 2, woman 2) and the movie theater department students trained for the experiment. Based on the expression that has been extracted, I collect the data of the facial muscles. Calculates the frequency of expression of the face and other parts of the body muscles around the mouth and lips, to be applied to the virtual character of the data. Orbicularis muscle to contract end of lips due to shrinkage of the Zygomatic Major is a upward movement, cheek goes up, the movement of the muscles, facial expressions appear the outer eyelid under the eye goes up with a look of smile. Muscle movement of large muscle and surrounding Zygomatic Major is observed together (AU9) muscles around the nose and (AU25, AU26, AU27) muscles around the mouth associated with openness. Duchen smile occurred in the form of Orbicularis Oculi and Zygomatic Major moves at the same time. Based on this, by separating the orbicularis muscle that is displayed in the form of laughter and sympathy to emotional feelings and viable large muscle by the will of the person, by applying to the character of the virtual, and expression of human I try to examine expression of the virtual character's ability to distinguish.

  • As recent advances in science, technology and performance requirements of the weapons system are getting highly diversified and complex, the performance requirements also get stringent and strict. Moreover, the weapons system should be intimately connected with other systems such as watchdog system, command and control system, C4I system, etc. However, a tremendous amount of time, cost and risk being spent to acquire new weapons system, and not being diminished compared to the rapid pace of its development speed. Defense Modeling and Simulation(M&S) comes into the spotlight as an alternative to overcoming these difficulties as well as constraints. In this paper, we propose the development process of virtual test framework based on the synthetic environment as a tool to analyze the effectiveness of the weapons system of underwater engagement model. To prove the proposed concept, we develop the test-bed of virtual test using Delta3D simulation engine, which is open source S/W. We also design the High Level Architecture and Real-time Infrastructure(HLA/RTI) based Federation for the interoperation with heterogeneous simulators. The significance of the study entails (1)the rapid and easy development of simulation tools that are customized for the Korean Theater of War; (2)the federation of environmental entities and the moving equations of the combat entities to manifest a realistic simulation.

  • The principle of Effective Based Operation applied to the Korean Theater resulted in measurable effects to win the minimum battle. Based on the finding, this study recommends the effect analysis methodology under the V-C interoperability system to acquire a weapon system. This method is followed as below; to confirm the effect data on the organized weapon system, to set MOE, MOP and effect considering the purpose of the analysis, to apply the appropriate operational concept and scenario on the weapon system, and then the available C Model is after action reviewed, adjusted, and given feedback. The V-C interoperability system enables to perform the real-time combat experiment under the virtual synthesized battlefield circumstances. The defensive battle organization and displacement of the future anti-tank guided weapon system was considered in the modeling process. Scenario was written, which encompasses company-level units and the battalion-level operation. Then the available AWAM was embodied and effect-analyzed, which formed the foundation of SBA.

  • The inter-disciplinarity in arts is not confined to recent issues. It has been sought to exceed the boundaries of each genre for the novelty and vision different from before. Among those efforts, this thesis focuses on the collaboration of Merce Cunningham and Robert Rauschenberg who were leading artists in 1960s. Their collaborative works marked with innovative concepts ever in performing arts. They pursued new possibilities in both dance and painting through reformist experiments of chance operation, or improvisational encounters of the unexpected. After the end of their collaboration, they developed their own artistic creations such as Cunningham's shifting from theater to video dance executed in virtual space of computer and Rauschenberg's new "Combines" series. This study examines how the two artists practically embodied the concepts of chance, impermanence and formlessness, centering around their meaningful collaborations from 1954 to 1964.

  • 360 VR technology is used not only in movies, but also in performing arts such as music, theater, dance, and so on due to the characteristics of immersion and presence. The technology allows the audience can be perceived a feel of participation in a story. This study is conducted an analysis of the techniques of 360 video shooting in order to find the answers of the following questionaries: how to make viewers enhance to a better understanding of a space, how to make the viewer feel comfortable ceding control of the experience, how to generate greater empathy with a 360 video. Thirty cases were analysed 360-degree videos of live performances performed on stage among 360-degree images of music performance content shared on Youtube from 2015 to 2020. The result shows that live performances are performed with the audience, so the stage shape and the layout of the audience seats are preferred to the characteristics of the performance. It was also shown that directing using a 360 VR camera was also greatly affected by the stage and audience placement. The stage is manly classified into three types, and the camera layout and characteristics mainly used are organized according to the number of 360 VR cameras, whether fixed or mobile cameras are used.
