In these days, the importance of design becomes increasing and the design aspect that customers decide to purchase products such as television, mobile phone is more important than functional one. And the progress of virtual reality technology enables us to feel the reality from the virtual prototype as the real one. In this paper, we introduce the collaboration design review system consist of MEMPHIS, CORE. We can create a realistic virtual prototype more fastly, conveniently and efficiently using MEMPHIS and carry out the design review through collaboration using CORE. As a result of this study, it would be possible that decision making can be done effectively at early stage of the design process.

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.

The purpose of this study was to investigate how student felt the strengths and shortness of presentation methods for formation of interior spaces. For this study, the process of the interior architecture design class was divided into three stages: the programming. the design development, and the design completion. In the design development stage, students used presentation methods: hand sketch, scale model, computer modeling, and virtual realty. The strengths of hand sketch was that quick expression. Models provided three-dimensional feelings. Computer modelling provide realistic color and texture. Virtual reality provided three-dimensional immersion and real scale. It is effective that students collect brain storm images using quick hand sketch in the beginning of design development stage. After that, they compose interior spaces in study models with small scale. Watching the models, they design details of spaces by using hand sketch and computer modelling. Using virtual reality, they can check the scale and circulation. Finally, they complete computer modelling by texture mapping and check the final design in virtual reality.

본 연구는 공간설계의 전반적인 참여를 위해서 가상현실을 적용시키는 방법론에 대한 논문이다. 현재의 공간설계의 참여는 일방적 정보전달의 과정, 정보이해의 어려움, 공간설계 단계의 제한적 참여라는 문제를 가지고 있다. 이런 문제점 해결을 위해 참여사다리의 마지막 단계로 제시되었던 PPGIS와 Geodesign의 비전인 가상현실은 참여의 수단으로 주목 받고 있다. 본 논문은 이러한 가상현실을 설계과정에 활용시키는 참여형 설계방법론을 제시하고자 한다. 이를 위해 본 논문은 참여와 가상현실에 대한이론 고찰을 통해 가상현실이 참여를 지원 할 수 있음을 확인하였고, 설계과정에서 가상현실이 수행해야 할 역할의 도출을 위해 설계과정과 참여과정을 비교하였다. 이 과정의 결과를 통해 가상현실을 활용한 참여형 공간설계 방법론을 제시한다. 또한, 방법론의 증명을 위해 설계과정에 적용하여 각 단계별 가상현실을 구현하고, 각 단계별 역할의 수행여부를 확인하여 방법론을 증명하였다. 증명의 결과로, 가상현실 체험을 통한 경험이 설계안을 효과적으로 이해시킬 수 있고 또한 가상현실을 통한 상호작용이 가능함을 증명하였고 이는 설계과정에서의 전반적인 참여가 가능하다는 것을 확인 하였다.

We have been designing human interactions for some learning support system or education system. The design is based on a symbol grounding model. The model is applicable to many learning domains using virtual reality technology. The design policy is simple and compact. In order to realize the policy we use/reuse some devices from the viewpoint of virtual reality. This paper introduces basic ideas and explains several example cases based on the idea.

Virtual reality is one of the key emerging technologies of the 21th century and it has been used in a variety of ways in the fields of architectural research. Virtual reality is presented as an ideal alternative for studying the interaction between space and humans because it provides a realistic spacial experience while allowing experimenters to control environmental variables at a low cost easily. It allowed us to deepen our knowledge of human spatial experience in the built environment. However, existing reviews do not include the following points: 1) previous review research has been focused on using virtual reality technology in construction and engineering, not spatial experience, 2) recently, some review researches started to study the interaction between space and humans in the built environment, however, they do not suggest specific concepts of spatial experience. The present review aims to examine the existing literature about measuring spatial experience using virtual reality in architectural design. The study conducted a systematic qualitative review that analyzes and synthesizes the evolving literature regarding design elements, methodology, and usability. The study concludes with an overall discussion and their potential for providing further directions for future research.

Time to market and cost-efficient production are some of the challenge that manufacturing industries face. Modern methods of engineering can't help such organizations attain competitive advantage. To help these situations, MEMPHIS (Middleware for Exchanging Machinery and Product Data in Highly Immersive Systems) was introduced as an approach that enables VE (Virtual Engineering) and links engineering applications with VR (Virtual Reality) solutions. Thus an environment is provided to implement virtual design reviews and enable the application of virtual prototyping methods. However MEMPHIS could just handle Product data for virtual design review and simulation. In this paper, we newly define and develop the extended MEMPHIS that enables virtual manufacturing with Process, Resource and Plant data as well as Product data.

가상현실은 오큘러스로 대표되는 웨어러블 장치의 도입과 함께 새로운 국면을 맞이하였다. 이에 본 연구에서는 영어학습을 위해 1인칭 시점으로 가상현실에 직접 몰입을 가능하게 하는 오큘러스 리프트(Oculus Rift) 기반의 몰입형 가상현실을 제안한다. 학습자 시점 기반의 몰입형 가상현실에 대한 전반적이고 통합적인 고찰을 통해, 언어학습을 위한 교수설계 시 고려할 사항을 제공하는 것은 의미 있는 일이다. 따라서 본 연구는 몰입형 가상현실의 언어교육 적용의 극대화 방안을 모색하는 것을 목적으로 한다. 이러한 연구 목적을 위하여 그간의 몰입형 가상현실의 교육적 활용 사례들을 살펴보았다. 그리고 몰입형 가상현실 기반 영어학습을 위한 설계 요소의 적용을 목적으로 학습이론의 설정, 학습의 차이 고려, 학습과제 선정, 교사의 영향력 규정, 적용 감각의 종류 결정, 설계의 융통성, 사용환경을 제안하였다. 그 결과들을 통합하여 교수설계에 대한 다양한 논의와 방향성을 제시하였다.

Visualized information platforms through building information modeling (BIM) such as virtual reality (VR) and augmented reality (AR) improves the efficiency of architectural information exchange. Despite that, less effort has been directed to evaluate the effectiveness of different BIM visualization platforms for architectural design review. This study fills these gaps and compares three BIM visualization tools for reviewing diverse architectural review factors and technology acceptance degree. Three main BIM visualization tools, which are desktop-based, virtual reality-based and augmented reality-based, were employed and different architectural review factors and user's technology acceptance degree was measured. As a result, VR and AR environment showed better visual presentation than desktop environment during design review. In terms of the technology acceptance level, VR and AR environments have received higher ratings compared to desktop environments. The detailed findings provide guidelines for participants and researchers involved in design review process to selectively adopt VR and AR system to various architectural design review components.
