The objective of this study was to test acceptance of, and interest in, a newly developed prototype of virtual reality enhanced mannequin (VREM) on a sample of congress attendees who volunteered to participate in the evaluation session and to respond to a specifically designed questionnaire.
A commercial Laerdal HeartSim 4000 mannequin was developed to integrate virtual reality (VR) technologies with specially developed virtual reality software to increase the immersive perception of emergency scenarios. To evaluate the acceptance of a virtual reality enhanced mannequin (VREM), we presented it to a sample of 39 possible users. Each evaluation session involved one trainee and two instructors with a standardized procedure and scenario: the operator was invited by the instructor to wear the data-gloves and the head mounted display and was briefly introduced to the scope of the simulation. The instructor helped the operator familiarize himself with the environment. After the patient's collapse, the operator was asked to check the patient's clinical conditions and start CPR. Finally, the patient started to recover signs of circulation and the evaluation session was concluded. Each participant was then asked to respond to a questionnaire designed to explore the trainee's perception in the areas of user-friendliness, realism, and interaction/immersion.
Overall, the evaluation of the system was very positive, as was the feeling of immersion and realism of the environment and simulation. Overall, 84.6% of the participants judged the virtual reality experience as interesting and believed that its development could be very useful for healthcare training.
The prototype of the virtual reality enhanced mannequin was well-liked, without interfence by interaction devices, and deserves full technological development and validation in emergency medical training.
本研究的目的是在自愿参加评估环节并回答专门设计问卷的大会参会者样本中，测试对新开发的虚拟现实增强人体模型（VREM）的接受度和兴趣。
开发了一款商用Laerdal HeartSim 4000人体模型，将虚拟现实（VR）技术与专门开发的虚拟现实软件集成，以增强对紧急场景的沉浸式感知。为评估虚拟现实增强人体模型（VREM）的接受度，我们将其展示给39名可能的用户样本。每个评估环节都有一名学员和两名教员，采用标准化程序和场景：教员邀请操作员戴上数据手套和头戴式显示器，并简要介绍模拟范围。教员帮助操作员熟悉环境。患者倒地后，要求操作员检查患者的临床状况并开始心肺复苏。最后，患者开始恢复循环体征，评估环节结束。然后要求每位参与者回答一份问卷，旨在探究学员在用户友好性、真实感以及交互/沉浸感等方面的感知。
总体而言，对该系统的评价非常积极，环境和模拟的沉浸感及真实感也是如此。总体而言，84.6%的参与者认为虚拟现实体验很有趣，并认为其开发对医疗培训可能非常有用。
虚拟现实增强人体模型的原型很受欢迎，不受交互设备的干扰，值得在急诊医学培训中进行全面的技术开发和验证。
