In these days the virtual reality technology has been applied to treat such an anxiety disorders. And also a medical doctor can diagnose the patient in distance with the telemedicine system. In this thesis, an telemedicine assistant system for treatment of acrophobia using biomedical signals and virtual reality technique is proposed. I made two virtual reality simulations for treatment of acrophobia and telemedicine system for communication between doctor and patient using personal computer. Multimedia conference service, online questionary, signal transfer system are needed to configure such system. Virtual reality simulation system that composed of position sensor, head mount display, and audio system, is also included in this telemedicine system. I added virtual environment update system to this virtual reality telemedicine system for treatment of acrophobia. With this virtual environment update system, the doctors can change virtual reality simulation stage based on the status of each patient and symptom of phobia. We will apply this system to the acrophobia patient in distance and be able to offer better medical treatment for mental illness in near future.

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.

Virtual and augmented reality technologies provide access to learning materials and improve the organization of a modern library's media space. This article aims to identify the significance and role of virtual and augmented reality technologies in the modern library's media space organization. Methodology. The research uses a university library case study methodology to empirically investigate virtual and augmented reality technologies. Results. Virtual and augmented reality technologies provide research and improve learning outcomes by engaging students and learners with significant interest in such technologies. Libraries offer users the opportunity to create their VR content through available software. Students can test their VR content in the libraries' labs. Libraries support access to a variety of virtual and augmented reality content. The content is accessed using "virtual reality headsets" for viewing and workstations with "authoring software and loanable 360 cameras" for creating. The library lab is a space to support students' digital creativity and research through virtual and augmented reality. There are 3D Design Labs within the libraries as a medium to large group design learning spaces with virtual reality technology. Libraries form a media space where users can create videos, podcasts, portfolios, edit media, and book tours, and students and researchers can explore different scientific knowledge. In this way, technology ensures that risks in learning are minimized as opposed to hands-on seminars and classes.

In this study, the factors affecting reality aspect of virtual reality system were identified through Quality Function Deployment. The influence of some selected factors was evaluated in simulated performance test. It was shown that the factor of whether user can break through the objects in virtual space is the most sensitive to performance, followed by the factors of rotation angle and movement step. Also, the results implied that as more referents were provided to user, feeling of reality was enhanced.

This paper presents an attempt to develop a visual programming language-based 3D virtual reality authoring tool intended to compose virtual interior space. The rapid development of digital technology and the wide spread of the Intenet have expanded the different uses of virtual reality in a number of applications ranging from interior design to building maintenance. In particular, the construction of cyber spaces based on existing interior spaces is becoming increasingly important. Current research, however, remains at the level of converting 3D models into virtual reality models, despite practitioners' needs for structural space models. Moreover, commercial tools to build virtual reality space have the disadvantage of targeting people who have professional knowledge of computer programs and computer graphics. Accordingly, the 3D virtual reality authoring tool developed in this research - called the VESL system - enables virtual and structural space to be easily composed using intuitive and interactive visual interfaces, which are based on visual programming techniques. The VESL system also provides an XML based semantic description of interior space, to be used to describe interior space information. We anticipate that the virtual reality spaces composed by this system will be of considerable use in the fields of architecture and interior design. Further research issues identified at the end of the research include developing a converter/filter for transforming Internet virtual reality standard language, or VRML, and evaluating the application of the system for practical use.

PURPOSE: This study examined the effects of posture improvement exercise using virtual reality programs on the posture and balance of patients with forward head postures. METHODS: Thirty men and women in their 20 s, who had a forward head posture, were divided randomly into a group with posture correction exercise and a group with posture correction exercise combined with virtual reality programs. The posture correction exercise was composed of squats, XCO training, and chin-tuck exercise. In contrast, exercise with virtual reality games involved the Hot Squat, Climbey, and Baskhead programs while wearing a headset. Both groups performed the exercises 15 min a day, three times per week, for four weeks. The balance ability, distance between the acromion and earlobe, and neck joint range of motion were assessed before and after the exercises. RESULTS: Both groups showed significant reductions in the distance between the acromion and the earlobe, along with significant improvements in the range of joint motion. The group that performed the virtual reality exercises showed a significant increase in the limit of stability. Both groups showed a significant decrease in the sway length. In contrast, the group given the virtual reality exercises showed a significant reduction in the sway speed while standing with their eyes closed. CONCLUSION: Exercise applying virtual reality programs can be used in clinical and home programs to correct the postures of individuals with a forward head posture because they can trigger interest in inducing active participation.

Purpose : The purpose of this study was to investigate the effects of virtual reality(VR) program on standing balance in stroke with sensory deficit. Methods : Subjects were assigned randomly to either VR group (n=28) or the control group (n=31) when study began. Both groups were conducted electricity therapy, exercise therapy 5 times per week during six weeks, and a group who have VR group 3 times per week during six weeks. Both groups assessed for standing balance before and after virtual reality program. Results : In standing balance, the virtual reality program which have sensory deficit in stroke group, open eyes from the center area of the body and center line significantly reduced the training period(p<.05). The virtual reality program to instantly move the weight through maximum voluntary safety limits to sensory deficit of virtual reality program(p<.05). Conclusion : Stroke patients with sensory deficit affects the recovery of the standing balance. In addition, virtual reality program was stroke patients with sensory deficit affects the recovery of standing balance.
