Background
-Increased fidelity and use of Driving Simulators-New vehicle designs are exploring advanced driving interfaces
(displays, controls, information)
Current Effort- Design a virtual motion simulation to enable
- trade studies- supplement Crew station tech demos(e.g. FTTS, CAT)
…that models the ground vehicle dynamics environment.
Goal-Satisfy FCS, Objective Force mobility, human factors requirements
-“operate on-the-move” (tele-ops, C2, increased op tempo) -“function without adverse physical effects” (mitigate sickness, info overload)

Experiment Protocol
Design of ExperimentsTwo fixed factors – HMD versus flat panelAnalysis - Independent variables: Fixed factorial, repeated measures2x4x2 (displays x vibration levels x course segments)
Dependent variables: road following, speed, long and latacceleration, steering wheel reversals, questionnaire ratings
12 subjects, civilian local population
Separate Multivariate ANOVAs- Vibration and course segments
Questionnaires(9) ANOVA
Determine influence ofdisplays, vibration, courseon driver performance.

Conclusions
Experiment not yet conducted (stay tuned)
Simulation design set up for vehicle/crew-station trade studies-Effects of Active, Passive Suspension, hybrids on Crew Performance-Joystick, yoke, steering wheel controls…feed-through vibration, and road feel characteristic settings?
-Optimum display design – what data & information to display,how to best render data – to make informed decisions
-Optimize camera locations
-Relatively? easy to modify simulation for tele-operations, UGV studies
