Designing for Inaccessible Emergency Medical Service Contexts: Development and Evaluation of the Contextual Secondary Video Toolkit

Designing technology for emergency medical services (EMS) can be difficult, for example, due to limited access to domain experts. To support designers who aim to engage in a participatory design process in EMS environments, we created and evaluated the Contextual Secondary Video Toolkit (CSVT). This method uses secondary video material and design cards that allow domain experts to identify and prioritise challenges in their work environment and generate design ideas that address them. We illustrate the effects of the CSVT on design processes by analysing four workshops during which aeromedical EMS staff explored the potential of augmented reality to support their work. Our results indicate that the CSVT can support reflection about work practices, aid the generation of design ideas, and facilitate genuine participation. Furthermore, our data indicates that the use of secondary video in design projects is appropriate and even has certain advantages compared to primary field video.
