Making Lifelike Medical Games in the Age of Virtual Reality

Medical simulations differ from other training modalities in that life processes must be simulated as part of the experience. Biological fidelity is the degree to which character anatomical appearance and physiology behavior are represented within a game or simulation. Methods to achieve physiological fidelity include physiology engines, complex state machines, simple state machines and kinetic models. Games health scores that can be used in medical sims. Selection of technique depends upon the goals of the simulation, expected user inputs, development budget and level of fidelity required. Trends include greater availability of physiology engines rapid advances in virtual reality (VR). In VR, the expectation for a naturalistic interface is much greater, resulting in technical challenges regarding natural language and gesture-based interaction. Regardless of the technical approach, the user's perception of biological fidelity, responsiveness to user inputs and the ability to correct mistakes is often more important than the underlying biological fidelity of the model.
