Minimum acceleration that humans can sense

Click For Summary
SUMMARY

The minimum acceleration that humans can sense is a well-researched topic, with studies indicating specific thresholds for detection. Research, including a study available on PubMed, highlights the role of the inner ear and visual cues in perceiving motion and orientation. Notably, the distinction between acceleration and velocity perception is crucial in understanding human sensory capabilities. Additionally, experiments demonstrate that slight vibrations can enhance balance and stability on a platform.

PREREQUISITES
  • Understanding of psychophysics and sensory perception
  • Familiarity with human anatomy, particularly the inner ear

I often travel by train. Sometimes, the train starts so slightly that I can not feel anything until look out of the windows. I know that's because of small acceleration.

The question is is there an acceleration threshold for human beings to be sensed?

I hope this is suitable for this box.

Thanks

Here is some light http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1402298 related to your question. It's a scientific study on psychophysical acceleration detection thresholds.
 
Thanks for the link
 
Interesting question. Our bodies have multiple methods of determining motion and orientation: eyes and inner ear in addition to motor neurons. There is also a difference in perceiving acceleration and velocity.

I recall a study showing that slightly vibrating a platform upon which subjects stood made it easier to balance and remain on the platform.

PubMed has quite a few articles under the search term:

acceleration threshold sensation human

scan and see what looks interesting...
