In this paper, two different flight training devices were constructed to verify the effectiveness of a pilot training system based on a Virtual Reality Head Mount Display. VFR Flight Procedure and IFR Flight Procedure were conducted by high level pilots with Commercial Pilot Licence. Flight data and pilot's visual data for each flight procedure were extracted, compared and analyzed with two training systems. Finally, the effectiveness of the training systems based on the VR HMD was demonstrated by assessing the given mission and the flight results.

Recent studies have reported about UAV-based disaster rescue system adopting AR technology. Performing a disaster rescue training in an environment similar to an actual disaster site results in high costs and risk of accidents. In this paper, we propose a simulation software using VR technology so that rescuer can safely and inexpensively train the operation of the disaster rescue system. Through the analysis of the existing system, we derived the requirements for virtualizing training, and developed the simulation software using Unreal Engine and Airsim API. Simulation results show that the proposed simulation software can effectively simulate the operation of the conventional disaster rescue system.

The rapid growth of virtual reality technology in the era of the 4th Industrial Revolution has accelerated scientification of combat training systems in addition to ICT(information and communications technology) in military field. Recently, research and development of simulators based on virtual reality have been actively conducted in order to solve sensitive issues such as increase of civil complaints due to the noise of a shooting range, prevention of shooting accident, and reduction of training cost. In this paper, we propose two key solutions: spatial synchronization method and modified point mass trajectory model with small angle approximation to overcome technical limitations of a current training simulator. A trainee who wears a haptic vest in a mixed reality environment built in MARS(medium-range assault rifle shooting simulator) is able to conduct not only precision shooting but also two-way engagement with virtual opponents. It is possible for trainee to receive more reliable evaluations in the MARS than an existing rifle simulator based on laser.

The sand table training is one of the most effective training method in military operations which can accomplish missions such as simulation and rehearsal without limitations related to time, space, money and so on. Previous sand table training has many problems like that the sand table cannot represent real field condition because of its physical properties. So, it is hard to be preserved and impossible to include much of information into them. In this paper, we make an approach based on Augmented Reality(AR) to solve these problems and propose an efficient military training briefing tool with virtual sand table environment described as actual battle field Virtual Tactical Map(VTM) can realize a virtual military training with simple action like moving marker or tangible interface by hand. Real-time state information of VTM gives us more organic intelligence for entire situation. Tangible AR interface provides users with a contents authoring tool that is natural, intuitive and easy to deal with as interaction between user in real world and system that augmented real world with virtual object. VTM is a newly designed military training briefing tools. A military training content can be reproduced and it is possible that user uses this content later. Thus, it shows us potential possibilities of AR applications on military leaning field.

Augmented reality systems are widely used in the fields of entertainment, shopping, education, and training, and the augmented reality technology is gradually increasing in importance. When augmented reality technology is used for education or training, it must be possible to represent different virtual objects depending on the work stage even for the same marker. Also, since the training content varies depending on the situation, it is necessary to describe it using a training scenario. In order to solve this problem, we propose a scenario markup language for an augmented reality system that can create training content based on a scenario and connect it with an augmented reality system. The scenario markup language for augmented reality provides functions such as a method for connecting a scene, a marker and a virtual object, a method for grasping the state of equipment or sensor value, and a method for moving a scene according to conditions. The augmented reality scenario markup language can flexibly increase the usefulness and expandability of the augmented reality system usage method and content usage.

지금까지 전범위 시뮬레이터에 의해 이루어진 원자력 및 화력발전소에서의 운전원교육은 실제 발전소 주제어실과 유사한 상황을 전개한다는 장점을 가지고 있으나, 주요 계통 및 기기에 대한 설명을 위해서는 교과서를 공유하거나, 강사의 지식을 칠판에 서술하는 방법으로만 진행되어 왔다. 전력연구원은 이러한 교육을 상당부분 강의실 컴퓨터를 이용하여 수행할 수 있다는데 착안하여 강의실용 가상발전소 교육훈련 시스템(VRPLANT)을 개발하였다. VRPLANT는 3차원 웹(Web) 기술을 적용하여 발전소 건물, 건물내의 주요기기 등을 3차원 가상공간에서 구축하여 Navigation할 수 있도록 하였으며, 주요기기에 대해서는 엔지니어링 데이터베이스가 연동되어 있어서 이동 중에 특정 기기를 선택하면 P＆ID, 논리도면, 기술설명서 등을 참조해 볼 수 있도록 개발하였다. 또한 기기들은 모니터상에서 분해 및 조립이 가능하여 기기의 형태, 내부구조 및 동작원리 등을 용이하게 이해할 수 있도록 하였다.

This analysis has been projected as a preliminary analysis to develop the therapy program for people who is suffering from stress disorder after car accident such as sense of fear or anxiety using virtual reality. The analysis verified the effect of driving scenario which is core technology of stress disorder program and of anxiety reduction training such as relaxation training through clients. The relaxation training has been tested to 8 people; 7 normal and 1 sufferer from car accident presenting them 3 different types of driving scenarios. As a result, relaxation training was effective but, it was not statistically good enough although it showed incensement of uneasiness by each different driving scenario. In spite of normal clients, it is interesting that anxiety lever after relaxation training using VR is lowered, but this result need to verify to client suffering real car accident.

The system components and implementation methods to be considered when constructing a system for plant safety training in a virtual environment were classified according to plant characteristics. When constructing a safety training system based on VR, the necessary components may be different according to the characteristics of the plant, and the basic system components to be built according to the target plant are presented. In order to support the proposed system, we implemented a city gas governor safety training system, which is a relatively simple facility. Through this, we propose guidelines for the construction of a suitable VR-based plant safety training system in the plant to be applied.
