Focus group domains, defining themes, and representative transcript excerpts

Domains	Definition	Representatives Statements
Experiential satisfaction	Overall impression of the simulation, particularly emotional valence and level of satisfaction	“I agree. It’s [AR] a super fun experience, honestly. Great way to learn, it’s fun.” “I thought it [AR] was really fun.” “I felt very excited, especially after the whole stimulation. My heart was kind of pumping and racing.” “It [AR] was very exciting. And you feel like a sense of responsibility with what you’re doing.” “I felt like it was really immersive. There’s a level of emotional excitement when you’re simulating something, so it makes the whole situation feel a little bit more intense.”
Learning engagement	Quality of the learning experience, including the perception of skills that were practiced and the realism of the scenario	“Doing it this way just seemed a lot more higher stakes. I could see the person dying. I think this is a great way to learn material.” “The components of a real-life situation with the beeping of the monitor added pressure and made it more emotionally realistic.” “It’s very different seeing a patient start to seize, instead of just reading it. And I think that was a huge thing. That’s a disconnect between book learning and clinical learning.” “I really liked that we could see the vitals change. I like that because it felt less of an exercise in imagination.” “I think like in terms of practicing communication, I think it definitely was more stressful than if we were just sitting in a room talking through the scenario. So definitely felt a little more intense which is probably good for practice” “I also liked the teamwork aspect of it. It’s difficult, I think, to really capture that in a setting, which is not emergency or not acute. And so having put us into a sort of stressful situation where something happened, which we weren’t expecting, was a good way to really engage our teamwork skills and to make sure or to assess if we can keep calm and work as a team, even though things are changing out of our control.” “I could almost smell the patient. I think it just took the educational material to the next level.”
Technology learning curve	Assessment of the feasibility, novelty, and ease of use of the software and hardware	“There’s fluency with the technology that only comes with using it.” “I think that there is a little bit of just startup cost to kind of understanding how to use the technology itself. And ways that could help with that.” “The setup was a bit challenging.” “It’s definitely not like anything I’ve done before.”
Opportunities for improvement	Areas where the simulation could benefit from added or modified features	“Maybe a syringe table or just a few more features in the room to make it feel like slightly more realistic.” “Maybe having something to hold in your hand…you could actually feel tired doing compressions…picking up a fake syringe would make it a bit more real.” “I think that I would have liked to see physical things. So instead of verbalizing actions, but instead physically placing defibrillator pads.”
