One key aspect for the safety and success of first responders’ operations is the compliance, during the intervention, with all the safety procedures and prescribed behaviors. Although real-world simulation exercises are considered as the best way to verify if operators are ready to handle emergency situations, they are not always a viable approach. Firefighting courses, for example, do not usually include this kind of activities, due to the numerous hazards related to deploying controlled fires for the simulation. However, traditional training approaches based on class lessons and multimedia learning material may not be particularly effective for teaching practical skills and procedural behaviors. In this work, the use of a Virtual Reality Training Simulation (VRTS) combined with passive haptic interfaces and a real-time fire simulation logic is investigated as a complement to a traditional video-based training approach used in the context of forest firefighting. The teaching of safety concepts and correct use of individual firefighting tools was selected as a use case, and a user study involving 45 trainees was carried out in the context of an existing training course. One third of the trainees attended the traditional video-based lessons of the course, whereas the remaining ones also took part to a practice training session, half of them with the devised VRTS, the others in the real world. Experimental results showed that the additional use of the devised VRTS improved the trainees’ procedural learning, as well as their motivation and perceived quality of the overall learning experience.
Intervention by First Responders (FRs) is essential in disaster response, and their preparation greatly benefits from continuous updates. However, the design of effective training experiences targeted to FRs can be very demanding from the viewpoint of a Training Provisioner (TP). Virtual Reality (VR) may have a key role to play in enhancing and facilitating this task. In fact, VR technology has already proven to be very helpful in the field of emergency training, as well as its use as a powerful design and mock-up tool in many other contexts. In this work, the application of VR as a mock-up tool supporting TPs in the arrangement and validation of a training experience, either real or virtual, is explored. In particular, a case study is considered concerning the training of an FR for hydro-geological risks. Within this context, the proposed approach is compared against dramaturgy prototyping, a method commonly used for the design of experiential courses. Results indicate that the adoption of a VR-based mock-up tool (VRMT) can provide TPs with good insights on the arrangement of the training and precious indications on how to actually map this information onto real-world exercises.
