Cardiac auscultation is an examination procedure that allows a medical professional to listen to heart murmurs while employing a stethoscope. Current auscultation training is seeing a trend in favour of employing diagnostics equipment, which in comparison to a stethoscope-based examination, provides a comprehensive visualization of the heart. However, despite employing advance auscultation equipment, heart diagnosis skills with the stethoscope are declining. The loss of such skills has caused concern amongst physicians, as the stethoscope remains widely available and affordable worldwide, unlike other specialized tools. Currently, simulation is being employed to improve the diagnosis of heart conditions since mastering cardiac auscultation skills requires extensive training due to the complexity of the heart murmurs. Moreover, high fidelity medical simulators provide realism and accuracy at a high cost, thus providing suitable training but limited practices depending on the number of trainees. In this paper, we present a 3D printed stethoscope user input device to be used in a non-immersive virtual cardiac auscultation examination training mobile application. We also describe the results of a preliminary usability study that involved participants using a 3D printed stethoscope, touch screen interactions, and a simulation manikin to examine a virtual patient.
