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

什么时候使用面向VR的培训特别有意义？特别是在真正的培训昂贵，耗时甚至危险的情况下，就像在某些医学领域一样，在救援行动（尤其是与志愿者）以及灾难管理中。

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 doctors
• 733,200 persons in non-medical service
• 23,000人没有直接就业（在2700名医疗服务中）
• 328,327人在护理服务中。

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名全职员工和20,000名志愿者
• Johanniter-Unfall-Hilfe：21,850名全职成员和37,218名志愿会员
• Malteser Hilfsdienst e.V. and Malteser Hilfsdienst gGmbH: 35,000 full-time employees and 51,000 volunteers

Why educate in Virtual Reality?

在该领域进行虚拟培训的反复论证是培训方案的灵活性和位置独立性。根据应用程序领域的不同，几乎没有努力可以设计和实施相应的数字现实。学习内容可以安全地传达，因为它们是虚拟的。进一步的优势包括可能提高患者的安全性，因为甚至可以反复实践复杂的过程和程序，并且可以详细了解“穿越身体的旅程”，以便将错误率最小化，以最大程度地减少干预措施。经常练习。

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.

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。

Since then, the small yet powerful BLK360 has been in use at the German Red Cross (GRC) for different projects, The nursing and hospital rooms in St. Ansgar Hospital (in cooperation with theCatholic Hospital Association Weser-Egge（KHWE）刚刚被扫描和数字化。

BLK360 3D激光扫描仪如何工作？

BLK360捕获环境与富尔语3 dl-colour panoramic images that are superimposed over a highly accurate point cloud. The BLK360 is the smallest and lightest instrument of its kind and is easy to use thanks to its one-button operation. Anyone who can handle an iPad can now capture the environment with high-resolution 3D panoramic images.

关于BLK360的一些事实：

• Enables scanning at the touch of a button in high, standard and fast resolution
• 是大约1公斤的轻量级（适合快递袋）
• 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

The advantages of training in VR

• 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
• Intuitive operation without special IT or programming knowledge
• Safe distance (in times of pandemics, like Corona)
• Increased patient safety
• Time saving
• 对志愿工作有吸引力

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。

In situations when in-person training is particularly challenging, costly or even dangerous, the use of Virtual Reality technology is useful and recommended. Flexibility of scenario design, location independence, safe and realistic learning environment make VR training a very good supplement to classical training. The German Red Cross Kreisverband Herford-Stadt e.V. and its partners, including Hexagon Geosystems, are successfully carrying out pioneering work in the field of VR training and are already making digital training a reality today.
