In recent years, training systems in various industrial fields have been made using virtual reality (VR) technology and widely used in education. Virtual reality based training system is safe, there is no waste of material, and there are many advantages to be able to practice anytime and anywhere. For example, virtual reality welding training simulation system is widely used for field worker because it can perform actual joining of steel plate in immersive environment. At this time, realistic representation of the steel plate joint is important to maximize the effectiveness of the training, but existing techniques have limited the natural expression of the effect. In this study, we propose a method of visualizing joint effect based on shader in order to construct welding training system. The results of this study can be applied to the welding training system to improve the weld training effect to provide the user with high-quality visualization.

Billiards is a fun and popular sport, but both route planning and cueing prevent beginners from becoming skillful. A beginner in billiards requires constant concentration and training to reach the right level, but without the right motivating factor, it is easy to lose interests. This study aims to induce interest in billiards and accelerate learning by utilizing billiard path prediction and visualization on a highly immersive augmented reality platform that combines a stereo camera and a VR headset. For implementation, the placement of billiard balls is recognized through the OpenCV image processing program, and physics simulation, path search, and visualization are performed in Unity Engine. As a result, accurate path prediction can be achieved. This made it possible for beginners to reduce the psychological burden of planning the path, focus only on accurate cueing, and gradually increase their billiard proficiency by getting used to the path suggested by the algorithm for a long time. We confirm that the proposed AR billiards is remarkably effective as a learning assistant tool.

Rapid growth in computer and digital-based technology has brought about changes in various human services including psychotherapy. This paper will look into one of these changes, focusing on a rising area of mental health therapy : Art therapy. Although development of art therapy is not so fast compared to other branches of psychotherapy, some art therapists are studying how to adopt and use it properly. Both art therapists and mental health experts have concluded that technology is a powerful tool despite its limitations and reservations. While some of them think that patients have benefited from the implementation of technology, others have felt concerns about the replacement of basic professional practices. The use of digital technology in the area of art therapy, however, continues to increase, encouraging patients to benefit from it in various therapeutic processes. This thesis therefore focuses on the analysis of literature related to digital art therapy published up to now. The following field study on Korean art therapists aims to examine the current practice of digital art therapy and discuss its feasibility and future. These two methods will contribute to enhancing the understanding of art therapy not only in theory but in practice and also suggest how digital art therapy may overcome limitations of conventional art therapy by exploiting its advantages. Furthermore, this study will present some clues on a possible new position of digital art therapy in the future. I hope that this analytical examination on digital art therapy will stimulate further discussion on this issue and particularly encourage more interdisciplinary work between art therapy and digital technology.

Recently, due to COVID-19, non-face-to-face online lectures are being held all over the world. In higher education in the post-corona era, distance learning has become the main teaching and learning method. At this time, Metaverse is being proposed as a new alternative. Metaverse has basic elements such as avatars, 3D space, and activities accompanied by interaction, which can be seen as a difference compared to existing VR (Virtual Reality) contents. This study designed and built an educational metaverse platform that can be applied to actual lectures by reflecting the three elements of the metaverse.In addition, we implemented a cross-device-platform that supports various devices such as HMDs, smartphones, tablets, and PCs by reflecting user requirements through usability tests such as middle school, high school, college students, and parents, so that anyone can easily participate in Metaverse lectures. Currently, the metaverse platform is being developed and serviced in various ways, but there are hardly any services designed for education. Just as services such as Zoom, the existing video conferencing solution, were used for non-face-to-face education, some functions of the currently serviced metaverse are utilized for education and used in the form of a one-time event. The educational metaverse platform developed through this study is expected to be a reference in constructing the metaverse for education in the future.

컴퓨터 기술이 발전함에 따라 디지털 게임 속 가상경관은 보다 정교해지고 있으며, 설계 및 구현 과정에서 고려를 요구하는 요소들이 증가하고 있다. 하지만 여태 가상경관 설계를 위한 정형화된 설계 방법론도 전무한 관계로, 디자이너들은 비효율적인 설계 과정을 거치며 동시에 질적으로도 만족스럽지 못한 결과물을 구축하고 있다. Ian McHarg의 도면 중첩법은 레이어 단위로 설계 고려요소를 정리하여 설계를 진행하기에, 설계에 고려할 요소들을 체계적으로 종합하는 디자인의 진행이 가능하다. 이에 본 연구에서는 도면 중첩법을 활용한 가상경관 설계 방법론을 구축하였다. 이를 위해서 우선 가상경관의 공간적 특수성에 따라 분류를 진행하는 분류 방법론을 문헌 조사를 통해 파악하여, 이들을 각각의 레이어로 조직하였다. 그리고 설계 영역으로서의 가상경관과 실공간의 차이점을 파악하여 이들을 기반으로 한 가상경관 설계 방법론을 구축하였다. 마지막으로 프로토콜 분석방법론과 공간 구성요소의 비교분석을 통하여 본 연구에서 구축한 설계 방법론의 유효성을 검증하였다. 검증 결과, 본 설계 방법론은 디자이너들의 작업 시간을 22% 이상 줄일 수 있었으며, 동시에 작품의 질을 향상시킬 수 있었다. 향후 본 설계 방법론은 디지털 게임을 비롯한 가상경관 설계 및 구현의 영역에서 활발한 활용을 기대할 수 있을 수 있으며, 나아가 가상경관을 조경 설계의 한 영역으로써 확장이 가능할 것임을 시사한다.
