Virtual reality (VR) technologies, which have been improved of late, offer experiences closer to reality than before. While VR technologies are expected to be an effective medium if used in learning content that cannot be offered in real life, distraction factors in VR technologies may prevent the users' presence and flow, making these technologies ineffective. Therefore, this study, through experiment and observation, analyzed the effect of distraction factors on the user's experience perception and learning effect when using HMD-based immersive VR. Experimental results revealed that the distraction factors were shown to have a negative, albeit not generally significant (except for tactile interactivity), effect on vividness, tactile interactivity, locomotive interactivity, presence, and flow. Ultimately, they were shown to have a negative effect on learning.

This paper compares VR cinema with interactive cinema from an interactive perspective to examine cinemas as a new medium. Rather than revealing the difference through this, the focus is on presenting a methodology that understands the cinema in a new environment that is now standing at the starting point. The development of video technology is changing not only the external elements of content but also the internal storytelling method, but the lack of killer content has always been pointed out as a problem compared to the remarkable development of technology. Therefore, it is necessary to specify the characteristics and types of interactions represented by VR (virtual reality) and new media represented by interactive media and to present directions. Therefore, the types and characteristics of interactions were compared with VR film produced in line with the new phenomenon and interactive film . Through this, we would like to present the meaning and value of the new film format from a media perspective.

Motivations to engage in internet shopping as well as traditional off-line shopping include both utilitarian and hedonic dimensions. It is important that online fashion retailers offer the sense of the real shopping experience that offline fashion retailers do. This article is to assess empirically virtual model impact on consumer's online shopping experience. To test hypothesis, an experiment was executed a field study on foreign internet shopping(www.landsend.com). Prior to administering the experiment, a pilot test was conduct among 20 undergraduate students to pre-test for computer system trouble and delay problem. The experiment was conducted to 90 studetns. The participants were instructed to answer all the questons based on their experience when using that particular internet shopping mall. The LISREL 8.50 was used for statistical analysis. The results indicate that the virtual model characteristics such as vividness, customization, and interactivity are important factors in affecting consumer's shopping experience. Online shopping experience have a strong positive effect on shopping mall loyalty.

본 연구는 가상현실, 증강현실, 혼합현실, 360도 동영상 등 다양하게 사용되는 차세대 실감미디어에 대한 사용자 관점의 이해를 목적으로 한다. 한 때, 3D 영상의 광풍이 불더니 곧 초고화질(UHD) TV가 그 자리를 차지하고, 지금은 가상현실이 실감미디어를 대표하는 그리고 차세대 먹거리 산업이라는 표현으로 미래 혁신 산업의 핵심 키워드로 자리하고 있다. 가상현실이 이렇게 산업적으로 중요한 역할을 함에 따라, 본 논문에서는 미디어 풍요성, 상호작용성, 프레즌스, 신체소유감, 사용자 경험 그리고 시지각과 같은 가상현실과 관련된 여섯 개의 이론적 접근을 통해 학술적 이해와 더불어 현장에 적용 가능한 가능성을 담아내고자 한다. 이 여섯 개의 이론은 3D 영상과 같은 실감미디어 연구에 많이 사용되는데, 미디어 풍요성과 상호작용성은 긍정적 또는 부정적 태도를 형성하는 주요한 요인이고, 프레즌스는 몰입을, 사용자 경험은 총체적 심리적 반응을 그리고 시지각은 '본다'라는 경험이 뇌의 활동과 더불어 얼마나 복잡한 과정을 겪는지 설명한다. 특히 신체 소유감은 그간 미디어 연구에 적용된 사례가 많지 않으나 가상현실 연구에 활용가능성이 매우 높은 이론으로 추후 실감미디어 연구에 많은 기여를 할 수 있을 것으로 보인다. 가상현실과 관련된 사용자 관점의 주요 이론은 가상현실을 연구하는 연구자는 물론, 하드웨어와 콘텐츠 제작자에게도 많은 함의를 제공할 것이다.

The purpose of this study is to examine a user-centered and interactivity-based user-participatory design that could be completed by users by helping them to better understand a diverse experience and be involved in a design process. The aspects of expression that were marked by direct user participation and subsequent interactivity in the areas of design, the arts and fashion were investigated to determine their characteristics. The kind of fashion that is characterized by interactivity is of significance in that it is variable according to the purpose of the users, it's possible to have sustained communication with them through their direct participation, and that the designer is consequently able to build a new, communicative relationship with the users as co-creators. This study found that the characteristics of interactivity through direct user participation are classified into four characteristics; One is playfulness. which offers a new experience and way to create fun and vale. Another is variability, which is changeability of form; the third is the convergence of technology and function. Lastly, the fourth is virtuality. This is to embody images in virtual space.

Digital simulation which was introduced to the architectural field due to the rapid growth of computer graphics, gave birth to a new type of contents called 'virtual reality', led by the interaction with the users and real time processing. The public attention is drawn to the virtual reality's potential as a next generational space simulation it, having the unique characteristics of 'simulation', 'interactivity', 'tole-presence', and 'immersion', is capable of taking a virtual tour of a space with a size equivalent to that of a real space, as well as proceeding with the design progress. Nonetheless, many problems impeding CPU's real time processing of an excessively loaded architectural model data have been pinpointed over the time. Yet such GPU based game engines as 'DirectX' and 'OpenGL', developed to deal with these impediments, have not been easily applied to the architectural simulation in the design process, due to the high license cost and the specific technical requirements for the system. The virtual reality has been developed and distributed centering around the gaming field, and game developers recently show a greater tendency to include level editors in the package for the expandability purpose. Thus, we plan to propose architecture simulation which utilizes level editors in this study. In addition, the compatibility of the game engine based level editors of Quake and Unreal which form the standards for the open source FPS games, based on VRML, the standard format for the virtual reality, was compared and analyzed. Taking the example of Villa Savoye of Le Corbusier, its application possibility as an architecture simulation was assessed, by measuring the extent to which the performance of such characteristic features of the virtual reality as interactivity, immersion, and tele-presence, was improved.

Virtual Reality (VR) represents a key technology for future shopping platforms. This study examined the effect of vividness and interactivity, the two technological characteristics of VR, and fashion involvement, a consumer characteristic, on a consumer's intent to use VR stores under the framework of the Technology Acceptance Model (TAM). The study explained consumers' belief in a new technology and the process underlying the use behavior. The survey was conducted on 200 people between the ages of 20s and 30s via an online survey firm. Data are analyzed using confirmatory factor analysis and structural equation modeling. The results showed that a greater level of perceived vividness had a positive effect on ease of use and playfulness, while perceived interactivity had a significant impact on usefulness and playfulness. The findings also indicated that consumers with a high degree of fashion involvement tend to perceive a higher level of playfulness through VR shopping. Regarding the effects of consumer beliefs, perceived ease of use had a positive influence on usefulness perception. A higher level of perceived usefulness and playfulness meant a higher consumer intention to adopt a VR shopping platform.
