Abstract: Preparation for mass casualty incidents (MCIs) is highly important but difficult to accomplish. Incidents are rare, often complex, and training is costly. However, with the development of consumer grade virtual reality (VR) hardware, immersive training simulations have become affordable for competency training. To make simulations effective, users have to be immersed and feel present in the simulation. We have developed a VR training system for MCIs in a user centered design process with emergency personnel and further improved the system to increase immersion and presence. In an evaluation with eighteen paramedic trainees, we compare six hypothesized design improvements between the two simulations, such as using a menu or a simulated emergency bag for interaction. Results indicate clear user preferences of interaction styles related to immersion and presence in MCI VR simulations.

Tilo Mentler. (2017). Applying Usability Engineering to Interactive Systems for Crisis and Disaster Management. In eds Aurélie Montarnal Matthieu Lauras Chihab Hanachi F. B.

Abstract: Crisis and disaster management are increasingly characterized by interactive systems intended to be valuable support for professionals and volunteers in preventing, preparing for, responding to and recovering from major incidents and accidents. Therefore, usability in terms of safe and efficient usage of computer-based solutions becomes a crucial factor for successful crisis and disaster management. In order to ensure usability, it has to be addressed systematically throughout any development process. In this paper, established engineering approaches to crisis and disaster management systems are summarized. Subsequently, resemblances (e.g. diversity of users and devices) and differences (e.g. scalability) between safety-critical contexts of medical device design and crisis management are outlined. Following this, recommendations for applying usability engineering processes to disaster management are derived from standards and guidelines according to medical device design (IEC 62366-1:2015, ISO 14971:2007). Particularly, relationships and interactions between usability engineering and risk managements measures (e.g. hazard-related use scenarios) are described.

Abstract: In the safety- And time-critical context of pre-hospital medical care, usability is a major challenge that needs to be addressed, because interaction problems or errors may have serious consequences for patients as well as employees of Emergency Medical Services (EMS). In this regard, a user-centered human-computer interface is a crucial factor for efficient usage as well as user acceptance. Well-established design principles can serve as directives throughout the analysis, design, implementation, and evaluation of applications. For standard PCbased applications the ISO standard 9241-110 serves as a practical guide since many years. However, new types of devices, especially mobile systems impose new challenges and ways of interpreting usability standards and guidelines. In this paper, we apply the ISO-Standard 9241-110 dialogue principles to mobile applications in EMS, considering the challenges of designing a system suitable for supporting users in both regular day-to-day services as well as rare Mass Casualty Incidents (MCIs).
