Accuracy requirements for physical models in serious games

Abstract

Many serious games use computer models of physical phenomenon (physical models) that simulate key aspects of the real- world environment within the virtual environment confronting the players. How accurate must the physical models be? One answer for physical models in serious games generally is given here using statistical hypothesis testing. The result is a quantitative test of model accuracy in light of a given application in a serious game defined in terms of 1) the random uncertainties (inherent and measurement) of the real-world phenomenon at issue, and of 2) the level of use of the physical model in the serious game. The accuracy test allows the developers of serious games and physical models to discuss whether more or less accuracy, and hence, more or less use-cost for a physical model, is required for the serious game. The accuracy testis illustrated using an example from serious gaming for maritime security using NURC'sOpenSea Tactical Theatre Simulator. © 2012 The Authors. Published by Elsevier B.V.
