Summary
Military tank simulators can cause motion sickness-like symptoms, including dizziness and nausea, in trainees. Performance decrements were linked to symptom severity, highlighting the need for simulator design improvements.
Area of Science:
- Military training simulations
- Human factors engineering
- Motion sickness research
Background:
- A new military tank driving simulator was implemented for training.
- Initial user reports indicated potential for motion sickness-like symptoms.
Purpose of the Study:
- To investigate the occurrence and characteristics of motion sickness-like symptoms in simulator drivers.
- To compare simulator-induced symptoms with those from real tank driving.
- To assess the objective effects of simulator use on performance.
Main Methods:
- Survey of 59 subjects on simulator-induced symptoms.
- Comparative analysis of symptoms between simulator and real tank driving.
- Objective performance and instability testing before, during, and after simulator use.
Main Results:
- Simulator drivers frequently reported symptoms like dizziness, nausea, disorientation, and hypersalivation, often with greater intensity than real driving.
- Real tank driving led to more prevalent sweating and drowsiness.
- Objective tests showed a greater performance decrement in subjects reporting more severe motion sickness symptoms.
Conclusions:
- Military tank simulators can induce a range of motion sickness-like symptoms in users.
- Symptom severity in simulators correlates with objective performance deficits.
- Simulator design may require adjustments to mitigate adverse effects and optimize training efficacy.
