Clinical simulation is an essential component of health professional education. Digital technologies can provide students with near-reality, interactive virtual simulation learning experiences on static and mobile appliances. Clarification is needed, however, regarding the various types of virtual simulation and the different program components. We drew on published literature to define virtual simulation modalities and to offer definitive terminology to clarify the nomenclature and composition of virtual simulation. Reporting should include description of ‘Fidelity’ ‘Immersion’ and ‘Patient’ to add clarity and utility to research in the field.
