Abstract: A training simulator provides an immersive virtual training environment depicting an operator performing healthcare tasks to a patient. The simulator includes a head-mounted display unit (HMDU). The HMDU includes a camera, a speaker, a display, and a sensor providing visual and audio output to the operator. The simulator also includes one or more controllers, each having a sensor. The controller sensors and the HMDU sensor output signals representing spatial positioning, angular orientation and movement data of the controllers relative to the patient. The simulator includes a data processing system that models and renders the patient including a condition of the patient, the operator, used healthcare equipment and supplies, changes to the condition of the patient and the used healthcare equipment and supplies, and sensory guidance as to the operator's performance of the healthcare tasks to simulate the virtual training environment and to evaluate the operator's performance.
