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.

Numerous scholars have explored the modeling, control, and optimization of energy systems in buildings, offering new insights about technology and environments that can advance industry innovation. Eye trackers deliver objective eye-gaze data about visual and attentional processes. Due to its flexibility, accuracy, and efficiency in research, eye tracking has a control scheme that makes measuring rapid eye movement in three-dimensional space possible (e.g., virtual reality, augmented reality). Because eye movement is an effective modality for digital interaction with a virtual environment, tracking how users scan a visual field and fix on various digital objects can help designers optimize building environments and materials. Although several scholars have conducted Virtual Reality studies in three-dimensional space, scholars have not agreed on a consistent way to analyze eye tracking data. We conducted eye tracking experiments using objects in three-dimensional space to find an objective way to process quantitative visual data. By applying a 12 × 12 grid framework for eye tracking analysis, we investigated how people gazed at objects in a virtual space wearing a headmounted display. The findings provide an empirical base for a standardized protocol for analyzing eye tracking data in the context of virtual environments.

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.

This study presents the angular effects of virtual vertices inserted for effective treatment of the boundary edge laid on an infinite conducting surface in a half-space scattering problem. We investigated the angular effects of virtual vertices by first computing the radar cross section (RCS) of a specific scatterer; i.e., a tilted conducting plate in contact with the ground surface, by inserting the virtual vertex in half-space. Here, the electric field integral equation is used to solve this problem with various virtual vertex angles (${\theta}_{\nu}$) and conducting plate inclination angles (${\theta}_r$) ranging from $0^{\circ}$ to $180^{\circ}$. The effects of the angles ${\theta}_{\nu}$ and ${\theta}_r$ on the RCS computation are clearly shown with numerical results with and without the virtual vertices in free- and half-spaces.

VR 가상현실 콘텐츠는 여러 분야에서 사용하는 매체가 되고 있다. 가상현실 콘텐츠가 현실감이 있기 위해서는 가상현실상의 물체들의 스케일이 실제의 크기와 같아야 하고, 또 같은 크기로 사용자에게 느껴져야 할 필요가 있다. 하지만 현실에서 느껴지는 캐릭터의 크기와 비교해서 가상현실 공간상의 캐릭터의 크기는 수치상으로 같은 크기로 제작했다 하더라도 사용자가 HMD로 영상안의 사물을 바라봤을 때 크기의 왜곡이 느껴지기도 한다. 본 논문에서는 가상현실상에서 크기와 관련된 요건들을 알아보고, 이러한 요건들이 가상현실에서는 어떠한 차이점을 가져오는지, 차이점이 사용자에게 어떠한 영향을 미치는지를 알아보고자 하였다. 가상현실 공간상에서 물체의 크기와 실제 공간에서의 물체 크기를 비교해보는 실험과 설문을 통해 원거리와 근거리에서 스케일의 왜곡이 어떻게 일어나고 있는지 살펴보고자 하였다. 이 연구가 가상현실 개발자에게 도움이 되는 연구가 되길 바란다.

본 논문에서는 가상현실 기술로 전 세계를 도보 여행할 수 있는 시스템을 제안한다. 가상 여행 콘텐츠에 대한 가상현실 이용자들의 관심이 높으나 기존의 가상 여행 콘텐츠는 체험할 수 있는 공간이 한정되어 있고 상호작용성이 부족한 문제가 있었다. 기존 콘텐츠의 단점인 현실감 부족과 제한된 공간의 문제를 해결하고자 본 시스템에서는 구글 스트리트 뷰 이미지를 사용하여 가상 공간을 생성하였으며 사용자는 실제 거리 이미지를 통해 현실적인 체험이 가능하고 구글 스트리트 뷰 이미지에서 제공하는 방대한 지역을 여행할 수 있다. 또한 가상공간 안에서 사용자의 상호작용성을 높이고 몰입감을 극대화 하기 위하여 가상현실 헤드셋과 트레드밀 장비를 사용하여 사용자가 실제로 도보를 하며 가상공간을 이동할 수 있도록 하였다. 실제 관광 명소에서 산길과 골목길까지 자연스러운 도보 여행이 가능한 본 시스템의 활용으로 사용자들의 여가 활동에 크게 기여할 것으로 기대된다.

Recently several methods have been developed for the virtual space construction. Generally, most of the methods are geometric-based rendering technic, but they are difficult to construct real-time rendering because of large data. In this paper, we present a three dimension image-based rendering method that enable a constant speed of real-time rendering regardless of object complexity in virtual space. The Proposed method shows good performance for the virtual space construction with high complexity.

In this study, presents geographic analysis of Heuksando Island We classified each area of the island according to physical attributes. Then, we derived the meaning of each area as a physical space and virtual space. In order to symbolize the events that happens around the spaces, we set directions and relations for those spaces. In this process, we figured the stages of voluntary experience that originates from the user's actions. This study proposes hierarchical categories of virtual environments from spacial reality, experience and the creation of simulacrum.
