Training simulator is an efficient and innovative tool to help users learn professional skills due to its convenience and safety. However, complex human–computer interaction is one of the main disadvantages that limit its effectiveness in safety training, especially for the rescue of a railway accident that requires collaborations. Through designing a set of task-specific hand gestures, we developed a training simulator for the recovery of a railway accident that helps the rescuers learn and practice rescue skills in a life-like environment and gain the firsthand experience. To test the validity of our training simulator, a user experiment is designed to compare it with the controller-based simulator in a between-groups study with 51 participants, focusing on different aspects of effectiveness. The results demonstrate that the hand gesture-based controller can be more efficient and usable to deal with complex interactions than the traditional hand-held controller.

基于手势的虚拟现实训练模拟器，用于铁路事故的协作救援

培训模拟器由于其便捷性和安全性，是一种有效的创新工具，可帮助用户学习专业技能。但是，复杂的人机交互是限制其在安全培训中有效性的主要缺点之一，特别是在需要协作的铁路事故救援中。通过设计一组特定于任务的手势，我们开发了用于铁路事故恢复的培训模拟器，可帮助救援人员在栩栩如生的环境中学习和练习救援技能，并获得第一手经验。为了测试我们的训练模拟器的有效性，设计了一个用户实验，将其与基于控制器的模拟器进行比较，该实验在51名参与者的小组间研究中进行，重点关注有效性的不同方面。
