Background and Goal Simulation
Design Requirements Simulation Design
Features Conclusions

• 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 Experiments Two fixed factors HMD
versus flat panel Analysis - Independent
variables Fixed factorial, repeated
measures 2x4x2 (displays x vibration levels x
course segments) Dependent variables road
following, speed, long and lat acceleration,
steering wheel reversals, questionnaire
ratings 12 subjects, civilian local population
Determine influence of displays, vibration,
course on driver performance.
Questionnaires(9) ANOVA
Separate Multivariate ANOVAs - Vibration and
course segments

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 controlsfeed-throu
  gh 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
