Eye movement measurement device based on simulated spatial disorientation scene

Abstract

The invention provides a device capable of providing a simulated spatial disorientation scene for a subject and meanwhile recording the eye movement condition of the subject. The eye movement measurement device mainly comprises a head-mounted display device for providing a visual task for the subject, an eye movement tracking module for recording the eye movement condition of the subject in real time, a vestibule electrical simulation device for changing an input signal of a semicircular canal of a vestibule organ of a human body and providing vestibule electrical simulation for the subject and a control computer for controlling the simulation manner, the simulation current mode, the strength and the simulation time of the vestibule electrical simulation device, controlling the visual task displayed by the head-mounted display device, displaying relevant parameters in real time and recording the eye movement data transmitted back by the eye movement tracking module in real time. By means of the device, the visual task and the vestibule electrical simulation can be exerted on the subject at the same time, and meanwhile the eye movement condition of the subject is recorded; and in this way, a researcher can investigate the eye movement condition when the vestibule task and the visual task are exerted on the subject at the same time, meanwhile the burden of equipment installation and set is lowered for the researcher, the good eye movement experiment condition is provided, and research on the spatial disorientation is facilitated.

Description

technical field [0001] The invention relates to the field of aeromedical engineering research, in particular to an eye movement measurement device based on a simulated spatial orientation disorder scene. Background technique [0002] Spatial disorientation is defined as the inability of a pilot to perceive the position, movement or altitude of his aircraft or himself in three-dimensional space. When space orientation disorder occurs, if it is not handled properly, the pilot is likely to lose control of the aircraft, causing serious accidents of aircraft crash and death. Current studies believe that the essence of spatial disorientation is that the human body's spatial orientation organs cannot meet the high-speed movement environment in 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 informatio...

Problems solved by technology

[0007] In the current eye movement test experiments, the subjects are usually in a static state or in a state of non-violent exercise. In these states, the vestibular organ cannot respond obviously, making it difficult to study the eye movement when the vestibular organ and the visual organ work at the same time.
