Vestibular illusion inducing device

Abstract

The invention provides a device for inducing a plurality of vestibular illusions. The device comprises a revolving chair device for changing the input signals of the semicircular canals of human body vestibular organs, a head shaking device for changing the input signals of the semicircular canals of the human body vestibular organs, a vestibular electrical stimulation device for changing the input signals of the semicircular canals of the human body vestibular organs and otolith, and a control computer for controlling the revolving speed and the revolving time of the revolving chair device, the shaking manner, the angular velocity and the shaking time of the head shaking device, and the type and the strength of the stimulating current and the stimulating time of the vestibular electrical stimulation device, and displaying related parameters in real time. According to the device for inducing the plurality of vestibular illusions, the devices are used independently or combined in use to effectively induce a plurality of vestibular illusions of a human body such as somatogyral illusion, coriolis illusion and somatogravie illusion; as a result, the device can be applied to the ground-based simulation of the vestibular illusions of pilots, and further can be applied to related training about the floor space disorientation of the pilots, and therefore, accidents caused by space disorientation can be reduced.

Description

technical field [0001] The invention relates to the research field of aeromedical engineering, in particular to a device for inducing various vestibular illusions in human body. Background technique [0002] Spatial disorientation is a major factor that seriously threatens flight safety and causes flight accidents. The essence of its occurrence is that the sensory organs used for spatial orientation cannot meet the high-speed motion environment of the three-dimensional space in the air. Therefore, spatial disorientation will inevitably occur to pilots during flight. [0003] Under normal circumstances, the pilot's correct spatial orientation depends on the input of sensory information from the visual system, vestibular system, and proprioceptive system, as well as the integration and coordination of the central nervous system. When any receptor in these sensory systems is not functioning normally, or some input information is inappropriate, it will affect the orientation a...
