Abstract

A method of medical training includes presenting a user with a medical scenario within a medical simulation in which the user plays a physician. The medical scenario includes an interaction between the user and a patient. Performance data corresponding to the user is identified. The identified performance data is based at least in part on an action of the user during the interaction between the user and the patient. The user is evaluated based at least in part on the identified performance data to determine whether the user has achieved a training goal within the medical simulation. The training goal is intended to improve a medical skill of the user.
