Recently, with the excessive uses of Internet, virtual spaces for the on-line introduced VRML are emerging. The inhabited virtual world includes a complex process and human experiences. The VR interactivity is now being examined, and it is the important aspect for creating VR application which may include navigating the virtual world, turning features on and off, and interacting with other users. Therefore, the study of this field is favored with a competitive advantage to the present and future multimedia designer. Thus, the subject of this thesis is for the design of virtual world, focusing on interactivity. The contents include the types of the VR interactivity, and their classifying and studying, according to the existing theories based on the literature and web sites. The types are for the user navigation, for the user interactions with other users and objects, and for the creation of metaphors. As the results of this study, it is suggested the effective application and the proposal.

The virtual patient dataset is a collection of diagnostic data from various sources acquired from a single patient into a coordinate system of three-dimensional visualization. Virtual patient dataset makes it possible to establish a treatment plan, simulate various treatment procedures, and create a treatment planning delivery device. Clinicians can design and simulate a patient's smile on the virtual patient dataset and select the optimal result from the diagnostic process. The selected treatment plan can be delivered identically to the patient using manufacturing techniques such as 3D printing, milling, and injection molding. The delivery of this treatment plan can be linked to the final prosthesis through mockup confirmation through provisional restoration fabrication and delivery in the patient's mouth. In this way, if the diagnostic data superimposition and processing accuracy during the manufacturing process are guaranteed, 3D digital smile design simulated in 3D visualization can be accurately delivered to the real patient. As a clinical application method of the virtual patient dataset, we suggest a decision-making method that can exclude occlusal adjustment treatment from the treatment plan through the digital occlusal pressure analysis. A comparative analysis of whole-body scans before and after temporomandibular joint treatment was suggested for adolescent idiopathic scoliosis patients with temporomandibular joint disease. Occlusal plane and smile aesthetic analysis based on the virtual patient dataset was presented when treating patients with complete dentures.

The navigation in 3D virtual space is a procedure which must be carefully established in advance with understanding of a complicate perception process. Although current various desktop softwares are suppling developers with easier production circumstances in accordance with popularization era of interactive 3D media it is true that previous systematic conceptual study has been performed exclusively at specific institutions. Therefore, based upon the examples of virtual reality research reported by universities and companies core concepts giving the background for navigation realization and direct/indirect factors supporting substantial realization were analyzed and discussed in this paper.

Recently, many people can experience the virtual space by smartphone, and they use many games. In particular, this change has great implications in the collaborative and communicative planning paradigm, which is residents' participation and agreement becoming important in community making and urban design. This study analyze the case of the five virtual space games about community making and urban design, and examine the related regal system. Game users can construct roads, houses, buildings and facilities in the virtual city. Then, they create profit, and promote the growth of virtual city. In these games, construction elements are classified residential, commercial, industrial, parks, green spaces, public building, and roads. But these elements does not identified clearly, and they mixed. By analyzing of related regal system, these games focus on the individual buildings, spaces, and facilities rather than considering the terms of urban planning. To complement the virtual space game with the aspects of urban planning, these games can encourage the participation capability and enhance the communication skills of citizens.

건물 및 주택의 가구배치나, 인테리어 디자인 등을 신규로 구성하거나 재배치하는 것은 고비용의 작업일 뿐만 아니라, 사용자가 정확히 판단하기 어렵다. 가상현실 시스템을 적용하면 공간적, 물리적 제약에 의해 현실 세계에서는 직접 경험하지 못하는 상황을 간접 체험할 수 있어 재배치에 대한 비용 및 시행착오의 오류를 줄일 수 있다. 따라서 본 논문에서는 EON Studio를 이용하여 건물 내부의 인테리어를 바꿔가며 디스플레이 할 수 있는 실내 인테리어 시스템 프로토타입을 제시하고자 한다. 현실 건물 내부와 가구를 EON Studio를 통해 구축한 후 회전 및 이동을 통해 재배치 도록 하였다. 구현된 시스템을 통해 제안된 인터페이스가 공간 배치 응용 분야에서 유용성 이 있음을 확인하였다.

ICT 기술이 발전하면서 놀이동산 같은 체험이 필요한 것들까지도 디지털화 하는 것이 가능하게 되었다. 최근에는 가상현실 기술을 이용하여 컴퓨터 시뮬레이션으로 창출된 3차원 가상공간에서 사용자의 오감 경험을 확장하고 공유함으로서, 기존의 놀이동산 게임에서 느낄 수 없는 3차원 현실세계와 유사한 경험을 추구할 수 있게 되었다. 따라서 본 논문에서는 가상현실을 이용하여 유저와 상호작용하고, 사용자에게 현실과 유사한 즐거움을 줄 수 있는 놀이동산 테마파크 게임을 개발하였다. 본 연구의 놀이동산 테마파크 게임은 Eon Studio 개발툴과 JavaScript를 이용하여 구현되었으며, Eon I-CUBE안에서 1인칭 주인공 시점으로 게임을 진행하도록 하였다. 또한 유저가 선택한 스토리 중심으로 놀이동산 테마파크를 구현하였다.

Persona means the mask of personality where the internal ego exposes itself to the outside. The complicated structure and diversity of contemporary society has provided men with a more variegated and diversified persona; in addition, advancements in internet and information communications creates the possibility for the emergence of more variegated and new persona. This study probes the persona of virtual space expressed in fashion designs; subsequently, this study reviews the concept and various characteristics of persona and examines the type of persona in the virtual space from the perspective of the manifestation of identity. The type of persona in the virtual space canbe categorized into flexible identity and falsified identity; subsequently, the characteristics and meanings of virtual space persona in fashion designs are analyzed. Flexible identity-oriented personas expressed in fashion designs are revealed through the images of animals or dolls. This is a childlike persona expression that expresses ego through other substances in an effort to express infantile substances such as dreams and fantasy cherished in childhood. Falsified identity-oriented personas are expanded as a realm of expression of the body and the realities are camouflaged as transformed persona. Negating existence itself by covering the eyes or face as well as the concealment of the body with masks or veils is an expression of a self-denying persona.
