Coriolis illusion

from Wikipedia, the free encyclopedia

In psychophysical perception , the Coriolis illusion (also known as the Coriolis effect) is the wrong perception of body orientation and the nausea caused by the Coriolis force . This effect occurs when the head is moved in opposite or similar motion with the body during a rotation and the sense of balance is impaired. This rotation of the head affects the semicircular canals in the ear, which cause a feeling of dizziness or nausea before balance is restored after the head returns to a stabilized state.

history

The Coriolis force was discovered by Gaspard Gustave de Coriolis in 1832 . By the end of the nineteenth century, the Coriolis force had become a common expression in meteorological literature. The Coriolis force is classified as the force of inertia applied to rotating objects. When applied to cognition, this occurs when a person's head gets out of alignment while rotating. When individuals rotate left along their y-axis and then push their heads forward, their heads are brought out of alignment and exposed to the Coriolis force and its effect. The manifestation of this effect is that individuals feel that their heads are tilted to the left. This can cause nausea, disorientation, and motion sickness. These feelings of discomfort appear in the body when the signals sent by the vestibular system and the visual system do not match; H. the eyes may tell the body not to move, but the finely tuned senses of the vestibular system indicate the opposite.

aviation

The Coriolis Illusion is a problem for pilots as it can lead to extreme disorientation. This happens when pilots need to speed up their aircraft and also need to check their instruments, which often involves moving their heads. This is particularly dangerous for an airborne pilot as he feels like he is pitching, yawing and rolling at the same time; in extreme situations this can lead to the pilot losing control of the aircraft.
