Virtual reality (VR) technologies have been applied as a professional training tool in a number of sectors.**Compared with traditional training methods in a real environment, VR training environments provide**significant advantages including, but not limited to, consistency across trainees, lower cost for reconfiguration**and upgrade, easy quantification of training results and efficiency. EXO (Operating as IVD Workforce Corp)**has been pioneering in this field, i.e. incorporating VR into the training curriculum for mission-critical**positions, such as nuclear power plant operators, riot-control police officers etc. One of the issues in**professional training for these mission-critical positions, both in physical and virtual environments, is the lack**of easy methods to assess the physical and psychological condition of trainees. Specifically, the level of mental**and physical stress cannot be accurately assessed during the training, making it difficult to ensure that the**simulated environment presents a similar level of stress to that encountered in the actual working environment**and scenario. This project aims at developing a wearable sub-system of EXO's current VR training system that**would allow real-time assessment of mental stress during training sessions, by acquisition and processing**electrocardiogram (ECG). The sub-system will be physically integrated with EXO's current head-mounted**display (HMD), and stress estimation algorithms will be light-weight in its computational requirement, so it**can be implemented in EXO's current embedded environment. The outcome of the current project will provide**a significant competitive advantage for EXO's VR training tool for missing critical personnel, as it can assess**the mental condition of the trainees in real-time, thus providing an added layer of information regarding the**effectiveness of VR training program, thereby maximizing the benefit of the VR training paradigm.

虚拟现实（VR）技术已在多个领域作为专业培训工具得到应用。**与真实的环境中的传统培训方法相比，VR培训环境提供了 ** 显着的优势，包括但不限于学员之间的一致性、更低的重新配置 ** 和升级成本、轻松量化培训结果和效率。EXO（作为IVD Workforce Corp运营）** 在这一领域一直处于领先地位，即将虚拟现实纳入关键任务 ** 职位的培训课程，如核电厂操作员，防暴警察等。这些关键任务职位的专业培训中的一个问题，无论是在物理环境还是虚拟环境中，缺乏简单的方法来评估受训人员的身心状况。具体而言，在培训期间无法准确评估精神 ** 和身体压力的水平，因此难以确保 ** 模拟环境与实际工作环境 ** 和情景中遇到的压力水平相似。该项目旨在开发EXO当前VR训练系统的可穿戴子系统，通过采集和处理 ** 心电图（ECG），** 可以在训练期间实时评估精神压力。该子系统将与EXO当前的头戴式显示器（HMD）物理集成，应力估计算法的计算需求将是轻量级的，因此它可以在EXO当前的嵌入式环境中实现。当前项目的成果将为EXO的VR培训工具提供重要的竞争优势，因为它可以实时评估受训者的精神状况，从而提供有关VR培训计划有效性的额外信息，从而最大限度地发挥VR培训模式的优势。
