Fidelity Analysis

The fidelity level of a simulation system is the level at which the simulated feature and perception of the user represents reality. Fidelity levels in simulators are determined generally for visuals, motion and sound. Dependent on the user requirements, the fidelity levels may be specific, representative or generic. IDT has developed a fidelity analysis process that considers the required cueing properties and features of a driving simulator. The cueing systems include vibration, sustained motion, yaw motion, onset motion, peripheral visual acuity, ambient light intensity, cockpit structure and car systems. A driver task analysis is performed from which the required cues from each cueing system is identified in order to perform that task at a certain level. Using this data, the required fidelity level of each cueing system is derived, which is used to define the technical specifications of the cueing system.
