Abstract:We propose a Virtual Reality (VR) solution for teaching Cardiopulmonary Resuscitation (CPR) in a dispatcher assisted scenario where the learner learns how to perform CPR in a single attempt. The goal of this research is to make it easier for a bystander to learn to perform CPR and to help improve the quality of CPR. The system that we created is called Augmented Reality CPR or ARC. Using immersive VR, the dispatcher is virtually present at the location where the victim and the bystander are. The bystander wears a Hololens that projects the dispatcher's representation over the real world. The dispatcher can use their hands and visual aids to help with giving instructions and feedback to the bystander. An experiment with 58 participants was conducted to compare ARC to the current way CPR is taught to bystanders, namely over the telephone. Participants of the experiment had to perform three different tasks; a chin lift, chest compressions and rescue breaths. The last two tasks were repeated eight times. Our findings support that ARC can make learning CPR easier for the bystander and we see an improvement in CPR quality when using ARC instead of a telephone. We found that ARC lowers the Mental Demand that the bystander perceives while learning CPR. We also found an increase in Perceived message understanding for the bystander. For the CPR quality aspect we looked at the chest compression task and found that ARC improves the compression depth and the hand position, while the compression rate is unchanged and the number of compression interruptions doesn't increase.
