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培训使用3D计算机图形，描绘了各种方案，使用户有尽可能接近现实的现场感觉。通过触觉或音频刺激增强的数字世界和用户的相互作用，自我观点和“存在”的感觉完成了虚拟训练的概念。

The use of VR in education

When does the use of VR-oriented training particularly 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 persons in non-medical service
• 23,000 persons without direct employment (out of 2,700 in the medical service)
• 328,327 persons in the nursing service.

此外，以下是德国最重要的援助和救援组织的全职和志愿雇员的数量：

• 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

Why educate in Virtual Reality?

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.

3D救护车数字化

早在2019年,Leica BLK360，the smallest 3D imaging laser scanner on the market, and the Leica Pegasus:Backpack, the mobile mapping laser scanning solution, were used to digitise an ambulance. The 3D data model of the ambulance was used to create a simulator being used for training purposes by paramedics (cooperation with the Fraunhofer IGD, among others).

3D digitisation of hospital rooms

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 the天主教医院协会Weser-Egge(KHWE) have just been scanned and digitised.

Further projects with the GRC and the天主教医院协会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.

How does the BLK360 3D laser scanner work?

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.

A few facts about the BLK360:

• 在高标准和快速分辨率的按钮下启用扫描
• 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

The advantages of training in VR

• 行动中人员的可靠性：在特殊情况下的例程可以反复培训
• Realistic environment with the feeling of being on-site
• Authentic learning impression
• Various exercise scenarios
• 重复的可能性training
• Safety of trainers and trainees during exercise in potentially hazardous places
• 没有特殊IT或编程知识的直观操作
• 安全距离（在大流行时期，像电晕一样）
• 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.

With all the advantages of virtual reality-based training, it must still be emphasized that VR education is a supplement and extension of the classic, traditional training. VR education can’t completely replace in-person training.

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。
