Virtual Reality (VR) as an educational medium is not a new topic. For more than 20 years, different solutions and concepts have been used for military and other public safety training. VR training is, though, new in health care, in rescue services (first responders, paramedics, nurses) as well as in disaster management.

What is Virtual Reality?

VR training uses 3D computer graphics that depict various scenarios giving users the feeling of being on-site, as close to reality as possible. The immersion in the digital world and the interaction of the users, enhanced by haptic or audio stimuli, the ego-perspective and the feeling of “presence” complete the concept of virtual training.

The use of VR in education

什么时候使用VR-oriented particul培训arly makes sense? Especially in situations where the real training is expensive, time-consuming or even dangerous, as in some areas of medicine, in rescue operations (especially with volunteers), as well as in disaster management.

A recent survey of the German Federal Statistical Office shows a theoretically large potential for VR training, measured by the number of employees in German hospitals. In 2017, full-time employees in 1,925 German hospitals were as follows:

• 161,200名医生
• 733,200名非医疗服务的人
• 23,000人没有直接就业（医疗服务中的2700名）
• 328,327 persons in the nursing service.

In addition, here are the numbers of full-time and volunteer employees of the most important German aid and rescue organisations:

• German Red Cross: 140,000 employees and 400,000 volunteers
• Deutsche Lebens-Rettungs-Gesellschaft: 560,000 members
• Arbeiter Samariter Bund: 41,000 full-time employees and 20,000 volunteers
• Johanniter-Unfall-Hilfe: 21,850 full-time members and 37,218 voluntary members
• Malteser Hilfsdienst E.V.和Malteser Hilfsdienst GGMBH：35,000名全职员工和51,000名志愿者

为什么在虚拟现实中进行教育？

A recurring argument in favour of virtual training in this area is the flexibility and the location independence of training scenarios. Depending on the area of application, a corresponding digital reality can be designed and implemented with little effort. The learning contents can be conveyed safely, since they are virtual. The further advantages include potentially increased patient safety, as even complex processes and procedures can be practiced repeatedly and higher learning effectiveness, as the "journey through the body" can be understood and practiced in detail, so that the error rate is minimised for interventions that have been practiced routinely and repeatedly.

Simulated, realistic environment

For the operational reliability in a rescue or emergency scenario, response teams (including voluntary helpers) can test different approaches and procedures directly in a simulated ambulance environment. The G RC Kreisverband Herford-Stadt e.V. (German Red Cross Herford City Association) is doing pioneering work in this area under the direction of Ralf Hoffmann, managing director of the district, and Thomas Pilz, honorary digitisation officer (both: DRK Kreisverband Herford-Stadt e.V.) in cooperation with Hexagon Geosystems among others.

3D digitisation of ambulances

早在2019年，Leica BLK360，市场上最小的3D成像激光扫描仪和Leica Pegasus：背包是移动映射激光扫描解决方案，用于数字化救护车。救护车的3D数据模型用于创建一个模拟器，用于培训目的（与Fraunhofer IGD等）一起用于培训目的。

3D digitisation of hospital rooms

从那时起，小型而强大的BLK360在德国红十字会（GRC）使用不同的项目，圣安斯加医院的护理和医院（与该项目合作）Catholic Hospital Association Weser-Egge(KHWE) have just been scanned and digitised.

Further projects with the GRC and theCatholic Hospital Association Weser-EggeKHWE for primary (emergency rescue) and secondary operations (intensive care and patient transport) are also forthcoming, such as the digitisation of the shock rooms as well as the examination and treatment rooms.

BLK360 3D激光扫描仪如何工作？

BLK360用全彩色全景图像捕获了3D的环境，这些图像被叠加在高度精确的点云上。BLK360是同类工具中最小，最轻的工具，由于其一键操作，因此易于使用。现在可以处理iPad的任何人都可以使用高分辨率3D全景图像捕获环境。

关于BLK360的一些事实：

• Enables scanning at the touch of a button in high, standard and fast resolution
• Is a lightweight of about 1 kg (fits in a courier bag)
• Takes less than 3 minutes to scan with full field of view (in standard resolution) and generate a spherical image at 150 MP
• Produces 360,000 laser scan points/sec

VR培训的优势

• Reliability of the personnel in action: Routines in exceptional situations can be trained repeatedly
• Realistic environment with the feeling of being on-site
• Authentic learning impression
• Various exercise scenarios
• Possibility of repeated training
• 在潜在危险的地方锻炼期间培训师和学员的安全
• 没有特殊IT或编程知识的直观操作
• Safe distance (in times of pandemics, like Corona)
• Increased patient safety
• Time saving
• Attractive for voluntary work

VR training also has many advantages for trainers. The introduction to the training is already integrated as a tutorial directly in the system. During the training, the integrated software can accompany the training process with clues or progress analysis in order to detect and minimise errors of the trainee. This reduces the supervision effort and accelerates the training. The training can be flexibly designed and is available anytime and anywhere. Trainees and instructors learn and work across locations, individually and yet jointly. This also strengthens the team spirit and motivates the stakeholders in a fun way.

凭借基于虚拟现实的培训的所有优势，仍然必须强调，VR教育是经典传统培训的补充和扩展。VR教育无法完全取代面对面的培训。

在面对面培训特别具有挑战性，昂贵甚至危险的情况下，使用虚拟现实技术是有用的和建议的。场景设计，位置独立性，安全和现实的学习环境的灵活性使VR培训成为经典培训的很好补充。德国红十字会Kreisverband Herford-Stadt E.V.它的合作伙伴，包括六边形地理系统，正在成功从事VR培训领亚搏苹果app域的开创性工作，并已经使数字培训成为现实。
