Standardized patients (SPs), individuals who realistically portray patients, are widely used in medical education to teach and assess students' skill in communicating with patient, eliciting a history, performing a physical exam, and others. They are typically healthy individuals with few or no abnormal physical findings. One limitation is that each SP can only portray a limited set of physical symptoms. We have developed a functioning prototype that uses sound-based augmented reality (AR) to expand the capabilities of an SP to exhibit physically-manifested abnormalities. Our current research using augmented reality technology allows the learner to view an abnormal virtual 3D heart on a normal SP's body in our simulated echocardiogram.
