Virtual and Constructive Simulations with the GRBIL Modeling Tool

The Graph-Based Interface Language (GRBIL) tool combines aspects of virtual and constructive simulations. GRBIL can be used to set up a virtual simulation where people can interact with a simulation of an operator interface and environment. Human-in-the-loop activity can be recorded when a person performs a procedure with the simulated interface. This activity can then be automatically compiled into an operator model that can be used in constructive simulations where the operator model interacts with the simulated interface. The operator model can then make human performance predictions.
