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.

In this paper, we propose applying interactive technology in virtual environments to enhance interaction and immersion by inducing more natural movements in the gesture recognition process through the concept of affordance. A technique is proposed to recognize gestures most similar to actual hand movements by applying a line segment recognition algorithm, incorporating sampling and normalization processes in the gesture recognition process. This line segment recognition was applied to the drawing of magic circles in the <VR Spell> game implemented in this paper. The experimental method verified the recognition rates for four line segment recognition actions. This paper aims to propose a VR game that pursues greater immersion and fun for the user through real-time hand tracking technology using affordance Elements, applied to immersive content in virtual environments such as VR games.

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.

Virtual reality technology is a new practical technology developed in the 20th century. In recent years, the related industry is rapidly developing due to the continuous development and improvement of virtual reality (VR) technology, and various image contents that are realistic through the use of virtual reality technology provide users with a better visual experience. In addition, it has excellent characteristics in terms of interaction and imagination, so a bright prospect can be expected in the field of video content production. This paper introduced the types of display of VR video, technology, and how users view VR video at the current stage. In addition, the difference in resolution between the past VR equipment and the current equipment was compared and analyzed, and the reason why the resolution affects the VR image was explored. Among the future development of VR video, we will present some development directions and provide convenience to people.

본 논문에서는 360도 카메라기반 식물 전자 상거래서비스 어플을 제안한다. 식물을 이용한 재테크 일명 "식테크"라고 불리는 재테크가 증가하고 있는 추세이다. 현재 다른 중고거래 플랫폼에서는 본 거래가 제안되어 있어 거래가 어렵고 일종의 재테크의 개념이라 전문적으로 거래하기 힘들다는 문제점이 있다. 이를 해결하기 위해 본 프로젝트에서는 실시간 차트를 활용하여 식물 거래가를 알려주고, 360도 카메라와 VR을 활용하여 식물의 육성일기 공유하여 어플 사용자들의 커뮤니티 장소가 되고, 은퇴 후 귀농을 하는 사용자에게는 식물을 잘 기르는 법의 정보를 알 수 있는 다방면에서 활용이 가능하여 여러 문제를 효율적으로 해결할 것으로 기대된다.

Global virtual reality (VR) and augmented reality (AR) markets are growing as VR and AR become a new source of revenue for industries around the world. In the edutech sector, an industry that combines traditional education, research on new innovative educational models and business models are scarce, and improvements are needed in the technology group and business environment to realize edutech in detail. Therefore, this study aims to define the elements strategically required for VR Toon development by comparing and analyzing the characteristics of existing touch panel-based display Toon and VR Toon content experiences. Tablet PC Toon and VR Toon were selected to conduct the research. Thirty people (19 men and 11 women) from their teens through their forties were surveyed using questionnaires. The questionnaires were formulated through a quantitative method by using AttrakDiff with a 7-point scale (-3: negative words to 3: positive words). Qualitative evaluations were also performed addressing nine concepts (satisfaction, novelty, operability, creativity, understanding, education, interest, participation, expressiveness). As a result, the usability test results of educational content using tablet personal computers and VR equipment were analyzed from the viewpoint of user experience to define elements expected to be strategically required for VR Toon development.

Virtual Reality (VR) has high potential to provide learners with rich learning experience based on a sense of presence and various interactions. The purpose of this study is to investigate the effect of career education programs for the future society using VR. To this end, 29 third grade students were given an eight-session education program, and changes in their perception of career and their overall opinion on the program were examined. The results are as follows: First, the VR-based career experience program for the future society had a positive effect on changes in the students' self-understanding and their attitude and perception of career. Second, the study subjects showed high interest in and satisfaction with the VR-based career education program. The results of this study suggested the need for the extensive use of VR in career education, the development of content considering achievement criteria and learners' characteristics, and the establishment of VR learning environments.

Recently, virtual reality and augmented reality technology have been extensively utilized in brand communication. The purpose of this study is to investigate digital reality contents as branded entertainment and content-analyze its format and contents for brand communication. Coding categories were derived to examine marketing characteristics of 300 digital reality contents and key descriptive statistics were presented and interpreted. The results revealed that consumer responses(i.e., view count, like, and dislike) toward Branded Digital Reality contents vary according to types of storytelling. Moreover, perceived values of contents also varied by the types of digital reality(VR vs. AR). Based on the results, this paper discusses the academical and managerial implications of study findings.

This study attempts to find out how science classes using VR content affect students' scientific attitudes and spatial senses. For 4th and 5th graders of an elementary school, a comparative class and an experimental class were set up for each grade, and a total of 11 classes were conducted for each grade. Before and after class treatment, pre- and post-tests were conducted on scientific attitudes and spatial sensations, and interviews with students were conducted during class. After all the classes for the research unit were completed, a survey was conducted to find out the changes in students' perceptions. As results of this study show, it was found that science classes applying virtual reality (VR) content have positive effects on students' scientific attitudes and spatial ability.

Most cultural contents currently we face are not suitable for associating with state of arts and high technology as simply providing one-sided learning. Pictures and movies of cultural contents also sees to utilize for efficacy of cultural education. There are still some limitations to draw interest from users when providing one-sided learning for cultural study, which aims to only deliver knowledge itself. In this paper, we propose interactive HMD VR cultural contents that can support more experience to get rid of aforementioned limitations. To this end, we first select quite interesting and wellknown cultural contents from world wide to draw more attention and effect. To increase immersion, presence and interactivity we have used HMD VR and Leapmotion, which intentionally draws more attention to increase interest. The cultural contents also facilitate augmented information as well as puzzle gaming components. To verify, we have carried out a user study as well.
