public abstract class Fuller extends Object implements Mental
Task-capability interface in accordance to Fuller (2011). Task demand is the sum of demands described by individual Tasks. These take exogenous information to describe the workload in fundamental relations. Task demand is divided by task capability to arrive at a task saturation. Task saturation is input to BehavioralAdaptations which alter parameters describing personal traits, such as desired headway and desired speed. In this way, task demand is kept at an equilibrium as described by Fuller.

A BehavioralAdaptation may also determine what the level of situational awareness is, which includes determining reaction time. Both situational awareness and reaction time parameters can be used in perception to model deteriorated perception due to a task demand imbalance.
