This study could begin with the improvement of computer graphic technology The graphic technology is the standards of computer technology level and up-to-date technology intensive. Above all, the technology of virtual reality has developed rapidly and the development of the program has changed from professional one only for the experts to easy of access ones for the space designers. Moreover, the program which major internet user's can experience the virtual model has been made, as the development of virtual reality technology that is based on the web. These graphic technology and the development of the web helped to extract human experiences on the space design step. However, to find the meeting point with real recognition is not easy though the virtual reality technology develops. Because the real space is made up of various senses that people feel in their surroundings. But, this study was possible because most of the space recognition is based on the visual organ, even though it can't satisfy all sensible factors that we feel in reality. Therefore, the significant of this study is the standards and criteria of evaluation, the technological proposal, expecting to make more advanced alternative design than before.

A haptic interface can be a passive system with virtual coupling as a filter virtual coupling has been designed for satisfying passivity. However, it affects transparency of haptic interface as well as stability. This paper suggests new design criterion of a haptic interface controller by considering transparency. As a result, sampling time and the range of impedance or admittance should be considered as well as virtual coupling for desired performance of hapticdisplay. And experiments show that the suggested design criterion can be applied successfully for desired performance.

With the continuous development of artificial intelligence using computers in the Fourth Industrial Age, the virtual space created by virtual reality experiences boosted by the power of artificial intelligence, provides a new experience for us. The purpose of this study is to explore the new aesthetics that the fashion industry provides to users in virtual space created by virtual reality technology. This research method is based on theoretical research on virtual reality technology and virtual space and constructs a research model applied to this research. The scope of this study is the application of virtual reality technology to fashion shows, fashion exhibitions, and fashion design apps on the website of professional virtual reality technology and fashion for the last five years from 2014 to 2019, which actively merged virtual reality technology with modern fashion. We will analyze the cases one by one. The results of this study are as follows. First, this study shows that the constructed virtual space of modern fashion using virtual reality technology creates three kinds of physical space, perceptual space, and imaginary space based on the commutative theory of virtual space formed by Swedish scholar J. $Widestr{\ddot{o}}m$. Second, virtual reality technology applied to fashion shows, fashion exhibitions, and fashion design apps is characterized by four aesthetic characteristics of presence, perceptual expansion, interactivity, and immersion in physical space, perception space, and imagination space.

This paper is on a participatory spatial design methodology using Virtual Reality, which can be applied to the overall spatial design process. Participation in the current spatial design has several limitations: one-sided communication process, difficulty of understanding the given information and partial participation in the design process. Virtual Reality can be an ideal visualization tool for Geodesign and PPGIS(Public Participation GIS), which is presented as a highest step at the participation ladder. A participatory methodology is proposed to take advantage of Virtual Reality. In order to support participation through Virtual Reality in spatial design process, theories about the participation are compared to derive the new roles of Virtual Reality and the roles are formulated in the participatory spatial design methodology. By applying the methodology to the design process and implementing each stage through Virtual Reality, the design performance of each step can be verified in the methodology. As a result, design ideas can be effectively understood through Virtual Reality experiences. It is also confirmed that the interactions in Virtual Reality and participation are possible in the entire design process.

The purpose of this study was to apply the Q methodology to type subjective perceptions of virtual clothing and to examine the characteristics of each type. Perceptions of virtual clothing were analyzed into four types. The first type was the "virtual clothing trusting fit grasping type," who preferred to use virtual clothing and believed that virtual clothing would help them grasp the fit. The second type was the shopping mall adoption-positive design understanding type, which believes that virtual clothing is useful for design understanding and that all shopping malls should have a virtual clothing system. The third type was the environmental pollution reduction virtual clothing purchase type, where the virtual clothing reduces environmental pollution and the user wants to purchase virtual clothing that cannot actually be worn. The fourth type was the actual clothing-like fun-seeking type, in which the virtual clothing resembles actual clothing and the shopper believes that the virtual clothing will make shopping more enjoyable. Depending on the type, the avatar was required to adjust the dimensions of the avatar, enhance the design expression of the garment, equip the avatar with decorative items, and produce virtual clothing for sale.

This study began with an assumption that virtual museum exhibitions will continue to be created in the future and more knowledge is required about designing effective virtual exhibit designs. This study explored the relationship between virtual exhibitions and visitor's opinions following the viewing of the virtual exhibit in order to determine the components of a well-constructed virtual exhibit design. To address the research problem, this study explored two aspects of virtual exhibit design: 1) what are the components of a well-constructed virtual exhibit, 2) how does viewing the virtual exhibit change visitors' opinions about both physical and virtual museum experiences. The methodology of the study employed surveys, interviews and observations as instruments of data collection. Twenty-five participants were given a survey prior to their viewing of the on-line exhibit, then they were given the opportunity to view the web-site and finally surveyed regarding their opinions. From the 25 participants, six were selected for observation to record behavior exhibited while they viewed the site. In addition, five were interviewed for a better understanding of their responses to various aspects of the virtual exhibit experiences. Data from the surveys was tabulated for descriptive percentages in order to identify numerical patterns of relationship. Observation data was analyzed for simple frequencies in categories of responses and interview data was tape recorded and transcribed into text files. Based on study results, recommendations were made for the future role of interior design in virtual space that stands independent from a physical building and resides only on the Internet.

In this study, we design an applicable model enabling internet protocol television (IPTV) service providers to use a virtual network (VN) for IPTV service delivery. The model addresses the guaranteed service delivery, cost effectiveness, flexible control, and scalable network infrastructure limitations of backbone or IP overlay-based content networks. There are two major challenges involved in this research: i) The design of an efficient, cost effective, and reliable virtual network topology (VNT) for IPTV service delivery and the handling of a VN allocation failure by infrastructure providers (InPs) and ii) the proper approach to reduce the cost of VNT recontruction and reallocation caused by VNT allocation failure. Therefore, in this study, we design a more reliable virtual network topology for solving a single virtual node, virtual link, or video server failure. We develop a novel optimization objective and an efficient VN construction algorithm for building the proposed topology. In addition, we address the VN allocation failure problem by proposing VNT decomposition and reconstruction algorithms. Various simulations are conducted to verify the effectiveness of the proposed VNT, as well as that of the associated construction, decomposition, and reconstruction algorithms in terms of reliability and efficiency. The simulation results are compared with the findings of existing works, and an improvement in performance is observed.

Model house play an important role in the sale of apartments. However, model house can create social and environmental problems. Virtual reality's (VR) use for the creation of model house has been studied as a possible counter measure to these problems. Existing models don't satisfy consumers' queries. A virtual model house can give the experience of seeing a real home through simulation. Also, a virtual model house can allow a home buyer to change the furniture on display or the color of the walls to reflect the consumer's taste in the construction. The internal present condition system using absorption style virtual reality and open style virtual reality are the indispensable tools that are going to take the place of the current model home. A virtual model house is more profitable than a physical model house because of reduced costs and time savings. In addition, a virtual model house can offer new kinds of information that a physical model home can not. This study's purpose is to discuss the desired direction of the virtual model house in this crucial and dynamic period of development.

Most of virtual reality systems ask users to control 3D objects or to navigate 3D world using 3D controllers. To maximize the human performance in the control, the design of virtual reality system and its input and output devices should be optimized. In this study, an experiment was designed to investigate the effects of three resolution factors of a virtual reality system on the human performance. Six subjects conducted the experiment for the factors; two frame rates, three spatial resolutions, and three pictorial contents. The result showed that the greater the spatial resolution was, the higher the human performance was. For the temporal resolution, fixed frame rate at 18 Hz was better than the varied maximized frame rate. For the pictorial contents, the virtual space with orientation cues marked the greatest performance than the other two conditions; the virtual space without any orientation cue and the virtual space like real world. These results could be applied for the design of virtual reality systems.
