본 연구는 완전 몰입형 가상현실 게임을 통하여 완전 몰입형 가상현실 동작과 실제 동작에서의 근수축 개시시간을 비교 하여 보고자 한다. 정상성인 30명을 대상으로 가상현실 동작(펀치, 활쏘기)과 실제 동작(펀치, 활쏘기)에서의 근수축 개시시간을 비교하여 보았다. 본 연구 결과 가상현실 동작과 실제 동작에서의 근수축 개시시간에는 유의한 차이가 없었다(p>0.05). 본 연구를 통하여 물리치료와 완전 몰입형 가상현실을 융합하여 새로운 완전 몰입형 가상현실 콘텐츠를 개발 하여 물리치료에 적용 할 수 있을 것으로 생각되며, 다양한 치료 방법이 개발 될 것으로 보인다. 또한 추후 연구에서 뇌졸중 환자를 대상으로 완전 몰입형 가상현실을 적용하여 치료에 적용 할 수 있을지 알아볼 필요가 있다.

본 연구는 실감콘텐츠에서 다양하게 나타나는 인터랙션 유형을 존 듀이의 경험이론을 통해 도출하고, 도출된 유형이 실제 사례에서는 어떤 방식으로 전달되는지 탐구하는데 목적이 있다. 이를 위해 국립중앙박물관 '디지털 실감 영상관'과 '아르떼미술관제주'의 두 사례를 경험이론에서 도출된 인터랙션 유형을 통해 분석하였다. 경험이론을 바탕으로 도출한 인터랙션 유형은 '다중감각'과 '동시체험' 그리고 '감각확장' 이다. 이 유형들이 두 사례에서 공통적으로 하나씩 접목되어 나타나기보다는 연결되어 나타났다. 단방향에서는 '다중감각'에서 '감각확장'으로 이어지고 양방향에서는 '동시체험'에서 '감각확장'으로 연결되었다. 이처럼 기술과 인간이 소통하는 핵심 유형은 한 가지씩만 전달되는 것이 아니라 다중적인 방법으로 인터랙션 순환 고리가 형성되었다. 따라서 실감콘텐츠의 인터랙션 유형은 1:1의 부분적인 전달 방식이 아닌 다방면에서 다양한 감각과 체험이 융합되어 단계적으로 확장된다고 볼 수 있다. 이를 바탕으로 향후 실감콘텐츠에서 인터랙션이 구현되었을 때 유형들은 어떻게 확장되고 관람객들에게 어떤 영향을 주는지의 연구가 필요할 것이다.

In recent years, Otome Games, as a popular game genre, have a considerable number of players in the game market and gained high profits. This paper explores the characteristics and influence of Otome Games by analyzing the audience group characteristics, narrative structure, audiovisual design, and other aspects of Otome Games. The study shows that Otome Games attract young women through immersive relationship experiences and diversified plot directions, but there is a trend of templatization in audiovisual design. Nevertheless, the genre's emphasis on high realism and sophisticated simulation systems continues to deliver a compelling immersive experience, making these games an integral part of players' lives.

In this paper, we propose a novel CALL (Computer-Assisted Language Learning) system, which is called POMY (POSTECH Immersive English Study). In our system, students can study English while talking to characters in a computer-generated virtual environment. POMY also supports haptic feedback, so students can study English in a more interesting manner. Haptic feedback is provided by two platforms, a haptic chair and a force-feedback device. The haptic chair, which is equipped with an array of vibrotactile actuators, delivers directional information to the student. The force-feedback device enables the student to feel the physical properties of an object. These haptic systems help the student better understand English conversations and focus on studying. We conducted a user experiment and its results showed that our haptic-enabled English study contributes to better learning of English.

As the level of consumption is improved and cultural life is pursued, the consumer's consciousness structure is rapidly changing, and the demand for product selection level, variety, and quality is becoming more diverse. The restaurant economy is falling due to the prolonged COVID-19, the economic recession, income decline, and changes in population structure and lifestyle, but the Meal- kit market is growing rapidly. This study aims to identify the consumer perception of Meal-kit, which is rapidly growing as an alternative to existing meals in the fields of dining out, food, and distribution due to the development of technology and social environment using big data. As a result of the analysis, the keywords with the highest frequency of appearance were in the order of Meal-kit, Cooking, Product, Launching, and Market and were divided into 8 groups through the CONCOR analysis. We want to identify consumer trends related to the key keywords of Meal-kit, present effective data related to Meal-kit demand for Meal-kit specialized companies, and provide implications for establishing marketing strategies for differentiated competitive advantage.

Recent improvements in technology have increased the consumption of virtual reality (VR) contents on immersive displays. The VR experience depends on the type of displays as well as the quality of VR contents. However, research on the impacts of VR content quality on VR experience and comparisons among different types of immersive display devices are lacking. In this study, VR contents created with our VR framework, are provided to participants on conventional two-dimensional (2D) immersive displays and VR headset. The geometric alignment of VR contents is improved with the addition of two calibration modes (i.e. preprocessing and straightening). The subjective feelings of presence and cybersickness experienced by participants while consuming VR contents created by our framework and commercial solutions are recorded in the form of questionnaires. The results of this study indicate that the improvements in VR quality lead to a better presence and less cybersickness in both conventional 2D displays and VR headset. Furthermore, the level of presence and cybersickness increases in VR headsets as compared to conventional 2D displays. Finally, the VR content quality improvements lead to a better VR experience for our VR framework as compared to commercial solutions.

Despite skepticism about commercial potential, the stereoscopic 3D cinema is still a form that any filmmaker can choose to employ for its aesthetics and its immersive potential. Based on a haptic illusion, the stereoscopic media content requires a new perspective different from the principle of 2D media content in terms of creation and acceptance. This paper examines the technical and aesthetic issues of stereoscopic 3D film production from the perspective of today's emerging realistic and immersive media through a case study. One of the key factors for successful content creation and research and development in stereoscopic 3D cinema is the combination of artistic principles together with technical mastering of the new image technology. The purpose of this paper is to outline the principal challenges and research topics in stereoscopic 3D cinema through a case study of stereoscopic 3D pilot film production for the 'User-Selective UHD Stereoscopic Media Service Platform' of the ETRI (Electronics and Telecommunications Research Institute). This paper intends to examine stereoscopic 3D filmmaking workflow and production methodologies, as well as technical elements and aesthetic issues.

Objective: This study aimed to explore the effects of balance training using fully immersive VR devices on the balance and walking abilities of stroke patients. Design: Randomized controlled trial Methods: This study involved 54 stroke patients divided into three groups: VRT(VR and traditional physical therapy), VR(VR only), and TPT(traditional physical therapy only). Interventions were administered twice daily for 30 minutes over eight weeks. Outcome measures included the Berg Balance Scale, Timed Up and Go Test, 10-meter walk test, gait analysis, and Activities-specific Balance Confidence Scale. Results: The VRT and VR groups showed significant effects on spatiotemporal variables and confidence compared to the TPT group (p<0.05). Specifically, the VR group demonstrated superior effects in TUG, 10MWT, velocity, stride length, single-leg support, and ABC compared to the other two groups (p<0.05). Conclusions: Fully immersive VR balance training had a positive impact on balance, walking, and confidence in chronic stroke patients. Traditional physical therapy alone showed limited effectiveness, highlighting the potential of VR-based interventions in stroke rehabilitation. These findings underscore the importance of integrating VR technology into clinical practice to enhance outcomes for stroke survivors.

본 논문에서는 수중에 존재하는 몰입형 에이전트의 움직임을 사실적으로 표현하고 수중 오브젝트들과의 상호작용에서 나타나는 외력을 시각적으로 표현할 수 있는 프레임워크를 제안한다. Unity3D와 HTC Vive를 이용해 사용자의 움직임을 추적하고 수중 물리적 요소인 부력, 저항력, 매그너스 효과를 몰입형 에이전트에 적용시켜 사용자로 하여금 수중에 작용하는 외력을 사실적으로 인지할 수 있게 한다.
