Exposure to motion within combat vehicles leads to increased perceived motion sickness, which is directly correlated with a decline in targeting accuracy. This human factors research insight is drawn from a 2006 study published in Human performance in extreme environments. Using Quasi-experimental, repeated measures design with 22 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers and researchers must consider the physiological and psychological impacts of motion on performance, especially in operational contexts where accuracy is paramount.

Human performance in extreme environments · 2006
Key Findings
- 01Perceived motion sickness increased following vehicle transportation.
- 02Perceived motion sickness was correlated with a perceived decrease in targeting performance.
- 03Subjective symptoms associated with motion sickness were identified as contributing factors to performance decline.
Application
Design takeaway
Designers and researchers must consider the physiological and psychological impacts of motion on performance, especially in operational contexts where accuracy is paramount.
How to apply
When designing vehicles or systems for dynamic environments, conduct user studies that measure both objective performance and subjective well-being, including motion sickness.
Project actions
- 01When studying performance, don't just ask people if they think they did well; measure their actual performance.
- 02Consider how environmental factors like motion can affect how well someone performs a task.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Uses a repeated measures design to control for individual differences.
- +Investigates a real-world operational context.
Limitations
It's hard to perfectly replicate the motion of a combat vehicle in a school setting, and subjective ratings can be influenced by many things.
Reliability & validity
The study's validity could be strengthened by including objective measures of targeting performance rather than relying solely on perceived decreases. Reliability of subjective ratings can be improved with standardized scales and clear instructions.
Think critically
How might the design of the vehicle's interior (e.g., seating, suspension, visual cues) influence the severity of motion sickness and, consequently, operator performance?
Design Principles
"Operator performance in dynamic environments is a function of both task demands and physiological/psychological state."
This research highlights a critical human factors issue in high-stakes operational environments. Understanding and mitigating motion sickness is essential for maintaining operator effectiveness and mission success in dynamic settings.
What This Means for Your Design
Riding in bumpy vehicles makes people feel sick, and when they feel sick, they can't aim as well.
How to use in your project
- 1.Reference this study when discussing how environmental factors, like motion sickness, can impact user performance in your design project.
- 2.Use the findings to justify the need for user testing that includes subjective well-being measures.
