This study aims to establish a foundation for autonomous driving on campus and communication of abundant university information in the HCI environment in a VR environment where college freshmen can freely travel around campus facilities. The purpose of this study is to develop a three-dimensional VR-style campus tour system to establish a media environment to provide abundant university information guidance services to freshmen in non-face-to-face situations. This study designed a three-dimensional virtual reality campus tour system to solve the problem of discontinuity in which VR360 filming space does not lead to space like reality, and to solve many problems of expertise in VR technology by constructing an integrated production environment of tour system. We aim to solve the problem of inefficiency, which requires a large amount of momentum in virtual space, by constructing a GUI that utilizes the motion of the field of view focus. The campus environment was designed as a three-dimensional virtual reality using a three-dimensional graphic design. In non-face-to-face situations, college freshmen freely transformed the HMD VR device, smartphone, FPS operation mode of the gyroscope sensor. The design elements of the three-dimensional virtual reality campus tour system were classified as ①Visualization of factual experiences, ②Continuity of space movement, ③Operation, automatic operation mode, ④Natural landscape animation, ⑤Animation according to wind direction, ⑥Actual space movement mode, ⑦Informatization of spatial understanding, ⑧GUI by experience environment, ⑨Text GUI by building, ⑩VR360, 3D360 Studio Environment, ⑪Three-dimensional virtual space coupling block module, ⑫3D360-3D Virtual Space Transmedia Zone, ⑬Transformable GUI(VR Device Dual Viewer-Gyro Sensor Full Viewer-FPS Operation Viewer) and an integrated production environment was established with each element. It is launched online (http://vautu.com/u1) by constructing a GUI for free driving mode and college information screens to adapt to college life for freshmen, and designing an environment that can be used simultaneously by current media such as PCs, Android, and iPads. Therefore, it conducted user research, held a development presentation, a forum on excellence in university innovation support projects, and applied it as a system on the website of a particular university. College freshmen will be able to experience university information directly from the web and app to the virtual reality campus environment.

Virtual human models are widely used to save time and expense in vehicle safety studies. A human model is an essential tool to visualize and simulate a vehicle driver in virtual environments. This research is focused on creation and application of a human model fer virtual reality. The Korean anthropometric data published are selected to determine basic human model dimensions. These data are applied to GEBOD, a human body data generation program, which computes the body segment geometry, mass properties, joints locations and mechanical properties. The human model was constituted using MADYMO based on data from GEBOD. Frontal crash and bump passing test were simulated and the driver's motion data calculated were transmitted into the virtual environment. The human model was organized into scene graphs and its motion was visualized by virtual reality techniques including OpenGL Performer. The human model can be controlled by an arm master to test driver's behavior in the virtual environment.

Haptic interface apparatus is the device which can offer users virtual reality not only by visualization of virtual space but also by force or tactile feedback. In this paper, we designed and fabricated a 2D haptic interface device that can be used for various purposes, and implemented a virtual air-hockey system that users can easily find in game rooms. By suitable modeling and haptic rendering, users can feel the impact and the reaction force with his/her hand holding the handle through 2D haptic interface device when he/she hit an air-hockey puck with the handle. Through the trial demonstration. we observed the reasonable effect of direction and speed of a ball like doing in reality.

가상현실(VR)은 현실 세계를 인공적인 기술을 활용하여 실제로 얻기 힘든 경험이나 환경 등을 제공해 인체의 오감(시각, 청각, 후각, 미각, 촉각)을 자극함으로써 실제와 같이 체험하게 하는 기술로써 게임, 영화, 스포츠, 테마파크와 같이 엔터테인먼트 목적으로 개발되는 경우가 많다. 본 논문에서는 Oculus Touch 및 Oculus Rift를 이용한 VR(Virtual Reality) 올림픽 종목의 스포츠를 설계하고 구현한 시스템을 제안한다. 올림픽 종목 중에 인기종목인 양궁, 사격, 테니스, 탁구 총 4가지 종목으로 구성되어 있으며, 특히 AI를 이용한 경쟁을 통해 종목별 스코어(점수)를 평가함으로서 경쟁구도를 형성한다. 또한, 시각적인 자극을 통해 흥미를 이끌어내고 현실적인 환경을 구현함으로써 유저가 실제 현장에 있는 것 같은 느낌을 제공하며, 세계적인 올림픽 스포츠를 유저들이 직접 즐기고 느낄 수 있다.

The purpose of this study was to analyze the affection of plan configuration on human emotion using Virtual Reality. A total of four different plan configuration was selected according to the prior study and built using Virtual Reality. The EEG was measured and then calculated using FFT to measure human emotion in different plan configurations. The measurements were shown to lead there was a significant statistical difference in four types of brainwaves between the plan types(p<0.05). This indicates that there is a possibility of plan configuration may exacerbate psychological disorder among single-person household and suggests that it is possible to counteract those stress among single-person household by changing the plan configuration in the earlier designing stage.

Owing to the environment in which it has become difficult to face people, on-tact communication has been activated, and online video conferencing platforms have become indispensable collaboration tools. Although costs have dropped and productivity has improved, communication remains poor. Recently, various companies, including existing online videoconferencing companies, have attempted to solve communication problems by establishing a videoconferencing platform within the virtual reality (Virtual Reality) space. Although the VR videoconference platform has only improved upon the benefits of existing video conferences, the problem of manually summarizing minutes because there is no function to summarize minute documents still remains. Therefore, this study proposes a method for establishing a meeting minute summary system without applying cases to a VR videoconference platform. This study aims to solve the problem of communication difficulties by combining VR, a metaverse technology, with an existing online video conferencing platform.
