In the past few years, advances have been made on how mixed reality humans (MRHs) can be used for interpersonal communication skills training for medical teams; however, little research has looked at how MRHs can influence communication skills during training. One way to influence communication skills is to leverage MRHs as models of communication behavior. We have created multiple mixed reality medical team training exercises designed to impact communication behaviors that are critical for patient safety, and found that MRHs can influence healthcare providers' behavior. This talk will discuss the results from these studies as well as the impact this work has on expanding the boundaries for how VR can be used.
