현재 증강현실 기술은 IT융합을 통해 여러 가지 분야의 응용서비스로서 활용가치가 점점 늘어나고 있으며, 스마트디바이스에서도 증강현실기술과 융합된 App을 쉽게 찾아볼 수 있다. 때문에 증강현실 기술을 광고나 전시회, 공연 같은 곳에서 활용하려는 시도는 활성화 되었지만, 아직 다른 분야의 증강현실 기술보다는 상대적으로 전문성이 떨어지며, 그중 환경모니터링과 연동되어 사용되는 서비스는 부족한 현실이다. 이에 본 논문에서는 이미 많은 지역에 광고홍보물의 목적으로 구축되어 있는 QR코드를 증강현실 기술과 접목하여 무인빌딩이나 자동화설비장과 같은 산업적으로 활용될 수 있는 QR코드와 환경감시센서를 활용한 스마트 디바이스기반 증강현실형 모니터링 기술을 제안하고자 한다.

본 논문에서는 스마트폰의 대중화로 인하여, 증강현실 기술 적용에 적합한 스마트폰용 위치기반 어플리케이션으로 골프정보시스템을 개발하였다. 골프는 목적지나 장애물까지의 정확한 거리와 모양 등을 정확히 알아야 하는 스포츠로서 증강현실기술 적용에 적합한 스포츠이다. 골프 스포츠의 대중화로 골프 인구는 지속적으로 증가하고 있으나 현재 출시된 골프관련 스마트폰용 앱들은 2D 이미지와 GPS기반으로만 구축되어 현장감 사실감이 많이 부족한 상황이다. 이에 골프장의 실제 환경에 따른 다양한 정보를 제공해 줄 수 있는 증강현실 기반 시스템으로 증강현실용 오픈소스인 Mixare를 골프스포츠에 유용하게 수정 보완하여 골프정보시스템을 개발하고 실제 골프장에의 적용에 대하여 기술하였다.

Interactive simulators that simulate mechanical systems are being developed for the purpose of performance evaluation of product design, replacement of physical training, and entertainment game. Use of flight simulator is increasing to reduce risk and cost of physical training, and we need virtual environment which covers large area terrain. We need a method that can reduce development cost and construction time of virtual environment that simulate the real environment. There have been attempts to link GIS or remote sensing field with virtual reality. This paper examines a method that helps to construct virtual environment, and attempts to link geographic information with virtual reality. A construction method of virtual environment based on digital map and satellite image has been studied.

This paper is concerned with the compression test and forming process of flange by using virtual reality and analysis(simulation) program. This virtual manufacturing can be carried out one personal computer without any expensive devices for experiment. The virtual manufacturing composed of three modules such as the imput, calculation and the output modules on internet. Internet user can give the material's property and process parameters to the sever computer at the input module. On the calculation module, a simulator computes the virtual manufacturing process by analysis program and stores the data as a file. The output module is the program in which internet user can confirm virtual manufacturing results by showing tables, graphs, and 3D animation. This programs is designed by an internet language such as HTML, CGI, VRML and JAVA ,while analysis programs use the finite increasing, the virtual manufacturing technique will substitute many real experiments in the future.

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.

An experience based training system concerning various fire situations which may result many casualties has been required to make rapid decision and improve the responsiveness. Recently, the necessity of virtual reality (VR) based training system which can replace a dangerous full-scale fire training and be easily adopted to the training or evaluation process is increasing. This study constructed tile virtual environment according to pre-defined scenarios, utilized the FDS(Fire Dynamics Simulator), three dimensional computational fire analysis program, to derive numerically simulated data on the propagation of fire. Finally, by visualizing the realistic fire and smoke behavior through virtual reality technique and implementing real-time interaction, we developed a VR-based fire training simulator. Also, in order to ensure the sense for tile real of a virtual world and reaI-time performance at the same time, we proposed appropriate data processing and space search algorithms, demonstrate d the value of proposed method through experiments.

Currently, as Korea enters into a fast aging society, the problem of dementia population is increasing. In this paper, we intend to contribute to the improvement of welfare for the elderly by developing virtual reality technology and related interface technology to effectively perform hand movements known as effective methods for preventing and treating dementia. As the content of the research and development of this paper, it is designed to be easy for the elderly to use and stimulate brain function by applying VR technology using sensors, and to activate mental and physical activities for the elderly who are marginalized in terms of cultural welfare. We intend to develop by classifying the types of games and contents that can induce them. As a result of this thesis, we developed contents using virtual reality to improve cognitive abilities for elderly people with poor cognitive ability to activate the brains of users' cognition, memory, and attention to prevent and treat dementia I want to contribute.

The number of buildings is increasing day by day. The next logical footstep is tackling challenges regarding scarcity of resources and sustainability, as well as shifting focus on existing building structures to renovate and retrofit. Many existing old and heritage buildings lack documentation, such as building models, despite their necessity. Technological advances allow us to use virtual reality, augmented reality, and mixed reality on mobile platforms in various aspects of the construction industry. For these purposes, having a BIM model or high detail 3D model is not always necessary, as a simpler model can serve the purpose within many mobile platforms. This paper streamlines a framework for generating a lightweight 3D model for mobile platforms. In doing so, we use an existing structure's site survey data for the foundation data, followed by mobile VR implementation. This research conducted a pilot study on an existing building. The study provides a process of swiftly generating a lightweight 3D model of a building with relative accuracy and cost savings.
