Virtual training is widely used based on safety and cost efficiency as a way to efficiently train based on virtual reality. In this paper, we propose the implementation and validation evaluation of life safety training, life training in closed area training, initial fire extinguishing training as a virtual training in maritime safety training. Specifically, we discuss how to implement virtual training to meet the goals of each training, and we propose training methods for evaluating trainees' effectiveness when implemented in this manner. The proposed evaluation method can be used as a quantitative evaluation index of the trainee's training assessment of the training and the safety contribution of the training to the evaluation of the training efficienc

Virtual training is a kind of training that proceeds as if it were a real situation. In recent years, there has been a growing demand for experiencing a situation in which a virtual reality technology has not been experienced directly in the real world due to the rapid development of the technology. Especially, safety education is very necessary in Korea where safety accidents are caused by many disasters. Therefore, simulation of disaster response training using virtual reality is more urgent than ever. Although the automatic defibrillator is the medical device that is most needed to rescue patients with cardiac arrest, few people know how to use it. Therefore, there are very few cases where the use of automatic defibrillators has saved the patient's life in Korea. The proposed Automated External Defibrillator virtual training system enables immersive and experiential training in real situations and effective training at low cost.

In recent years, there has been an increasing interest in tangible sports simulators with the success of golf simulator. The main purpose of this study is to develop a tangible snowboard simulator for the beginner using virtual reality technology. This paper proposes an interactive virtual coach and high fidelity virtual environment for snowboard training. The virtual coach offers an intuitive guidance and personalized coaching feedback about the 5 fundamental riding skills. The virtual training environment uses the stereoscopic display system and motion platform to create more realistic training situation. We expect virtual reality will be used as a training aids in many sports such as taekwondo, baseball, archery and so on.

In this paper we propose a VR-based Sailor Training Platform Authoring Tool which efficiently trains sailors in immersive ways. Proposed authoring tool consists of virtual environment reconstruction that imports real ship indoor environment into virtual environment and script editing which is able to implement various scenarios in emergency based on just drag-and-drop interface. The aim of importing real ship environment and supporting various VR devices is to enhance immersiveness and training so that trainees can deal with serious emergency events. Also the usefulness of the interface enables to reduce the cost of making training materials. Throughout scenario editing interface, the proposed authoring tool supports the editing of multi-user scenario and setting individual task for the evaluation.

This paper presents a VR-simulated sailor training platform for emergency in order to prevent a human error that causes 60~80% of domestic/ abroad marine accidents. Through virtual reality technology, the proposed platform provides an interaction method for proficiency of procedures in emergency, and a crowd control method for controlling crowd agents in a virtual ship environment. The interaction method uses speech recognition and gesture recognition to enhance the immersiveness and efficiency of the training. The crowd control method provides natural simulations of crowd agents by applying a behavior model that reflects the social behavior model of human. To examine the efficiency of the proposed platform, a prototype whose virtual training scenario describes the outbreak of fire in a ship was implemented as a standalone system.

In recent years, virtual training has attracted a lot of attention because it is as effective as traditional in-person training and provides more cost-effective and safer learning environment. However, the existing virtual training systems rely on the evaluator's qualitative judgement when evaluating and analyzing trainees' performance. Additionally, evaluation and analysis functions are only available on certain systems so those functions need to be developed for each system. In this paper, we propose an extensible evaluation and analysis system for virtual training using experiential knowledge collected from experts for providing effective evaluation and analysis. Specifically, we provide a method of applying Open API so that the proposed system works with different types of virtual training system. In addition, the experiential knowledge is constructed in advance for the evaluation and analysis so that the efficiency of the evaluation with the comparison target is increased. This experiential knowledge can be quantitatively compared to trainees' performance according to the proposed evaluation and analysis procedures.

대형화, 복잡화 되어가는 대형 기계설비의 위험상황에 대한 실제 훈련은 소요시간 및 비용 증가, 훈련자 안전 확보의 어려움, 반복적인 훈련 및 평가가 어렵기 때문에 가상현실을 이용한 훈련 시뮬레이터가 대안으로 제시되고 있다. 본 논문에서는 대형 기계설비 안전대응 시뮬레이터에서 수행된 훈련에 대한 훈련자 피드백 및 평가를 위하여 개발된 시스템을 소개한다. 가상현실 기반 훈련 시뮬레이터에서 수행한 훈련결과 데이터를 활용하여 훈련 시나리오 내 임무수행 여부, 수행시간/거리에 대한 정량적 평가와 함께 훈련자의 훈련동작 데이터와 표준동작과의 비교를 통하여 효율적인 훈련을 위한 피드백을 수행할 수 있다. 또한 평가 결과의 시각화를 통해 직관적인 훈련개선이 가능하도록 하였다. 개발된 훈련평가 시스템을 활용하여 효과적인 훈련자 피드백 제공 및 반복적인 훈련 수행을 통한 안전대응 능력 향상이 가능할 것으로 판단된다.

본 논문에서는 증대하고 있는 재난안전사고에 효율적으로 대응할 수 있도록 훈련할 수 있는 시뮬레이터 플랫폼을 제안한다. 최근 재난은 복합적이며, 타 부처 간의 협력이 필요한 대규모 성격을 띠고 발생하는 빈도가 커지고 있는 반면 훈련도구는 각 부처별로 재난유형별 시스템들이 필요에 따라 독립개발 및 운영되고 있기 때문에 다양한 시나리오에 의한 종합적 분석결과를 기반으로 하는 스마트한 재난대응 방안 모색이 어려운 실정이다. 이러한 이유로 본 연구에서는 재난에 대응하는 사람의 다양한 능력을 반영하여 인공지능 기반 하에 훈련 시나리오가 생성될 수 있는 지능형 재난대응훈련 시뮬레이터 개발을 위한 플랫폼을 제안한다. 또한 몰입감을 가지고 가상의 상황 하에서 훈련할 수 있도록 가상현실 기반의 시뮬레이터 플랫폼이 될 수 있도록 제안한다.

본 논문에서는 가상훈련 기반 소방안전교육에 관한 것으로, 건물 내 화재 발생 시 대처할 수 있는 방안에 대한 방법론을 제시한다. 기존의 소방교육은 오프라인 형태로 여러 명이 모여 훈련을 받아야 하는 만큼 공간적, 시간적 제약이 많다. 이러한 시공간적 제약을 없는 체감형 훈련 방안을 시스템으로 구축하고, 소방 훈련 콘텐츠를 탑재한다. 건물 내 화재 발생시 5분내 초기 대처가 중요한 만큼. 가상훈련의 실제 5분을 기준으로 훈련 방법을 제시한다. 본 소방안전교육 시스템은 HMD(Head Mounted Display)을 적용하여, 3차원의 입체 디스플레이를 적용하며, 훈련자의 움직임에 따라, 가상공간 내 실시간 반영될 수 있는 기술을 포함한다.
