Bárány chair

The Barany chair or Bárány chair, named for Hungarian physiologist Robert Bárány, is a device used for aerospace physiology training, particularly for student pilots.

Test

The subject is placed in the chair, blindfolded, then spun about the vertical axis while keeping their head upright or tilted forward or to the side. The subject is then asked to perform tasks such as determine their direction of rotation while blindfolded, or rapidly change the orientation of their head, or attempt to point at a stationary object without blindfold after the chair is stopped. The chair is used to demonstrate spatial disorientation effects, proving that the vestibular system is not to be trusted in flight. Pilots are taught that they should instead rely on their flight instruments.

Uses

The device is also used in motion sickness therapy.[1]

Nobel Prize

Bárány used this device in his research into the role of the inner ear in the sense of balance, for which he won the 1914 Nobel prize in Physiology or Medicine.

gollark: If it broke can we trust the output? I suppose it depends how it breakeded.
gollark: Chorus City dwellers: would you be interested in a subway-type thing based on small train lines underneath the roads?
gollark: Well, the chatbox tell has limits.
