  7. Abstraction hierarchy as a space for describing simulator fidelity

  8. Critical issues in simulator fidelity • Functional fidelity rather than physical fidelity • Fidelity should be tuned and described relative to the experimental question • Scale event detection relative to “effective visual acuity” in describing resolution of simulator display • Vehicle dynamics relative to vehicle control • “High-fidelity” may not be adequate

  9. Fidelity: Why push the lower bounds? • Increasing fidelity can undermine experimental control • Increasing fidelity limits data collection • Increasing fidelity dilutes training • Increasing fidelity can make people sick • Fidelity=fnc(understaning-1)?
