'''Human-in-the-Loop''' lends itself the ability for the user to change the outcome of an event or process. HITL is extremely effective for the purposes of training because it allows the trainee to immerse themselves in the event or process. The immersion effectively contributes to a positive transfer of skills acquired to the real world. This can be demonstrated by trainees utilizing flight simulators in preparation to become pilots.

HITL also allows for the acquisition of knowledge in regards to how a new process may impact a particular event. Utilizing HITL allows participants to interact with realistic models and attempt to perform as they would in an actual scenario. HITL simulations bring to the surface issues that would not otherwise be apparent until after a new process has been deployed. A real world example of HITL simulation as an evaluation tool is the Federal Aviation Administration’s (FAA) use of HITL simulation to allow air traffic controllers to test new automation procedures by allowing controllers to direct the activities of simulated air traffic while monitoring the impact the newly implemented procedures.<ref>Sollenberger, R.

== Human-in-the-Loop Simulation within Virtual Simulation Taxonomy ==

Virtual simulations inject '''Human-in-the-Loop''' in a central role by exercising [[motor control]] skills (i.e., flying an airplane), [[decision making]] skills (i.e., committing fire control resources to action), or [[communication skills]] (i.e., as members of a [[C4I]] team).

Although '''human-in-the-loop''' simulation can include a computer simulation in the form of a synthetic environment, computer simulation is not always a form of human-in-the-loop simulation, often this type of simulation is considered human-out-of-the loop simulation. In this particular case a computer model’s behavior is modified according to a set of initial parameters. The results of the model differ from a true '''human-in-the-loop''' simulation because the results can easily be replicated time and time again by simply providing identical parameters.
