The purpose of this study is to investigate the potential of immersive environments in the design domain by analyzing students' design process in immersive environments from cognitive and experiential aspects. To do this, we reviewed major concepts and theories such as users' immersion, participation, presence, and awareness and developed a comprehensive conceptual framework of immersive shared environments. In three different visualization systems of HIVE, teams consisting two students were assigned to design tasks and the design process was analyzed by a customized framework. The characteristics of the immersive environment related to the performance of the design task were different from those of the previous studies. The perception of the relationship between the spaces is very important, and the perception of the surrounding objects is interested in the shape or the material such as whether the object is flat or inclined. Also, it is found that the multi-technology of immersive environments is very useful for creative collaboration. In the future, a more comprehensive analysis of the effects on design decisions in a more diverse visual interface condition and the effects on more diverse design areas should be added.

본 연구는 몰입형 가상현실에 존재하는 다수의 HMD 사용자들에게 보다 향상된 현존감과 만족스러운 경험을 제공하기 위하여 협업기반 다수 사용자 상호작용을 제안한다. 제안하는 다수 사용자 상호작용의 핵심은 가상현실 환경에 존재하는 HMD 사용자가 각자 구분된 역할과 행동을 기반으로 소통과 협업을 통해 상호작용할 수 있는 방향을 제시하는 것이다. 가상협업환경에 존재하는 사용자 각각은 손을 활용하여 가상 환경 또는 가상의 객체와 직접적으로 상호작용하는 기본 구조를 바탕으로 사용자간 소통과 협업을 통해 공동의 목표를 수행해 갈 수 있는 방식(동기화, 의사소통)을 함께 설계한다. 그런 다음 제안하는 다수 사용자 상호작용을 통해 향상된 현존감과 만족하는 경험을 제공하는지를 검증하기 위하여 소통과 협업을 고려한 아케이드 장르의 가상현실 어플리케이션을 제작한다. 그리고 참가자들을 대상으로 한 설문 실험을 진행한다. 이러한 과정들을 통해 제안한 몰입형 가상협업환경에서의 상호작용이 사용자 모두에게 만족하는 현존감과 경험을 제공함을 확인한다.

In this paper, we describe our vision of a "Just-in-time" initiative to solve the Data Interoperability Problem (a.k.a. INTEROP.) We provide an architectural overview of our initiative which draws upon existing technologies to develop an immersive and collaborative approach which aims at empowering data stakeholders (e.g., data producers and data consumers) with integrated tools to interact and collaborate with each other while directly manipulating visual representations of their data in an immersive environment (e.g., implemented via Second Life.) The semantics of these visual representations and the operations associated with the data are supported by ontologies defined using the Common Logic Framework (CL). Data operations gestured by the stakeholders, through their avatars, are translated to a variety of generated resources such as multi-language source code, visualizations, web pages, and web services. The generality of the approach is supported by a plug-in architecture which allows expert users to customize tasks such as data admission, data manipulation in the immersive world, and automatic generation of resources. This approach is designed with a mindset aimed at enabling stakeholders from diverse domains to exchange data and generate new knowledge.

기능성 게임은 사용자에게 재미와 함께 특정한 학습 목표를 달성하기 위한 훈련 또는 교육의 경험을 제공하는 것이다. 본 연구에서는 몰입형 메타버스 플랫폼에서 여러 훈련생과 감독자 들이 서로 실시간 동기화된 자신들의 아바타들 간 협업을 통해 화재 탈출 훈련을 제공하는 기능성 게임을 제안하고 구현하였다. 제작된 시스템 아키텍처는 착용형 동작 센서와 헤드 마운트 디스플레이로 구성되어 메타버스 사이버 공간에서 각 사용자의 의도된 행동을 사용자의 아바타의 동작과 동기화시킨다. 개인화된 착용형 시스템은 사이버 체험 기반의 화재 대피 훈련 시스템에 편리한 사용자 인터페이스와 몰입형 환경을 저렴한 구성 비용으로 제공할 수 있도록 한다. 본 연구의 기능성 게임은 건물의 화재 현장에 대해서만 구현되었으나 제안하는 플랫폼은 공공의 안전을 위한 다양한 재난 상황에 대해 구성을 확장할 수 있다. 본 시스템의 실험 결과를 통하여 제작된 시스템이 화재 탈출에 필요한 능력을 향상시키는 훈련 효과를 검증하였다.

최근, 몰입형 가상현실(IVR) 환경에서 가상 객체(Virtual Object)를 이용한 상호작용을 통해 교육, 의료, 산업, 원격지 협업 등 다양한 서비스에 활용되고 있다. 특히, 인공지능(AI) 기술을 접목하여 가상 휴먼을 사용자에게 가시화하고, 상호작용을 수행하는 연구가 활발하게 진행되고 있고, 이를 확장한 가상 반려동물에 관한 연구도 시작되고 있는 단계이다. 몰입 VR공간에서 가상 반려동물과 상호작용을 수행하기 위해서는 실제 환경에서 반려동물과 신체 접촉(쓰다듬기 등) 및 제스처와 같은 비언어적 상호작용(Non-verbal Interaction)이 소통을 위해 중요한 것처럼 가상 환경에서도 이러한 상호작용의 재현을 통해 몰입 경험을 높이는 요소에 대한 영향 분석이 필요하다. 본 논문에서는 몰입형 VR 환경에서 사용자가 가상 반려동물과 상호작용 체험을 수행할 때 패시브 햅틱(Passive Haptic)을 제공하고, 그 촉각(Tactile) 요소에 대한 영향 분석을 수행하였다. 패시브 햅틱의 촉각(Tactile) 요소를 모양(shape), 재질(texture) 항목으로 분류하여 그 변화의 정도에 따라 상호작용 효과에 어떠한 영향이 있는지 측정하였다. 실험 결과, 패시브 햅틱 피드백이 제공되는 몰입형 가상 환경에서 가상 반려동물 상호작용을 수행할 때 재질 요소의 단계(Level)의 차이에 따라 몰입감(Immersion), 공존감(Co-presence), 사실감(Realism), 친근감(Fridenliness) 측면에서 통계적으로 유의미한 차이가 있다는 것을 알 수 있었다. 또한, 재질과 모양에 따른 통계적 상호작용 영향 분석에서 친근함 측정 결과에서 불쾌한 골짜기(Uncanny Valley) 효과가 있다는 것을 확인하였다. 본 논문의 연구 결과는 가상 반려동물 상호작용을 수행하는 콘텐츠 개발에 가이드라인으로 기여할 것으로 기대된다.

This paper, as a conlcusion to this special issue, presents the future work that is being carried out at NTU Singapore in collaboration with Microsoft Research and Microsoft Azure for Research. For our research team the real frontier research in world histories starts when we want to use computers to structure historical information, model historical narratives, simulate theoretical large scale hypotheses, and incent world historians to use virtual assistants and/or engage them in teamwork using social media and/or seduce them with immersive spaces to provide new learning and sharing environments, in which new things can emerge and happen: "You do not know which will be the next idea. Just repeating the same things is not enough" (Carlo Rubbia, 1984 Nobel Price in Physics, at Nanyang Technological University on January 19, 2016).

In this paper, we propose sharing 3D media between multisite using enhanced Access Grid (e-AG) which is a composition of 3D display and Access Grld (AG) Conventional AG and other collaborative systems have a limitation to share immersive 3D media Thus, proposed system supports sharing 3D media contents in a AG meeting section. Real object can be shared by acquiring stereo image with pre-calibrated stereo camera and by delivering, and virtual object can be shared by transmitting state information after downloading 3D model. And also, real video scene acquired by stereo camera and virtual object from 3D model can be displayed on the 3D display system of each node adaptively. The characteristics of proposed sharing method are sharing 3D media, displaying 3D media on a system adaptively, supporting real-time interaction. The proposed sharing method will be used remote lecture, remote collaboration with 3D media.

Recently, immersive VR/AR contents have actively increased, and various services related to VR/AR allow users to experience remote places. For example, if failure situations occur frequently in factory of the remote site, mixed reality (MR) with a synthetic virtual human expert in reconstructed remote location can help immediate maintenance task with interaction between the operator and the virtual expert. In this paper, we present a technique for synthesizing the virtual human after capturing a 360-degree panorama of a remote environment, and analyze the effects to apply a method of guiding virtual human by interaction types. According to this paper, it was shown that co-presence level significantly increased when verbal, facial expression, and non-verbal animation of the virtual human was all expressed.

Architectural & Interior design communication is a process of exchanging information between architects and other professionals, clients, and prospectus users, and a design medium is a means of communication. Using non-immersive, conventional media, it is challenging for architects communicate physical details and users' activities in not yet built three-dimensional buildings to others. Recent advances online, Multi-User Virtual Environments (MUVEs) allow architects and other professionals to experience a virtually constructed building together using anthropomorphic avatars. In addition, MUVEs also enable them to be aware of the presence and activity of each other. Previous studies suggest that the aforementioned characteristics of MUVEs may facilitate communication between architects and others. But these are focused on communication in controlled experimental conditions. This paper discusses the ways in which MUVEs are applied for authentic and long-term collaboration, design studio, and cultural heritage reconstruction projects, produced by digital design group at the UC Berkeley and the Technion-Israel Institute of Technology, and analyzes the influences of MUVEs on those projects. MUVEs helped more precise communication between architects, electronic engineers, and medical staffs, who are collaborating for developing pioneering technology for hospitals. In design studios, MUVEs allowed students to experience other students' design outputs, and thus helped them share ideas mutually. In addition, in cultural heritage reconstruction projects, MUVEs were used for communicating with historians and residents in order to collect evidence. Based on this study, we propose that MUVEs have strong potential for enhancing the communication between architects and other professionals.
