A simulation method and system for rapidly inducing fatigue state based on audio-visual stimulation

Abstract

The present invention provides a simulation method and system for quickly inducing a fatigue state based on audio-visual stimulation. The steps of the method are: storing multiple categories of pictures and sounds of different frequencies, and setting corresponding simulation buttons according to the picture category and sound frequency; randomly displaying pictures Or play sound, and set the picture display and sound playback time; the user selects the corresponding analog button according to the displayed picture or the played sound, and marks the user's choice; collects the user's brain wave, builds a brain network model, and Coherence was calculated from the brain network model as an indicator of fatigue-inducing effectiveness. The present invention simulates the process of inducing fatigue through visual and auditory perspectives, greatly shortens the time for inducing fatigue, reduces the cost of inducing fatigue, shortens the time for inducing fatigue, and reduces the cost of inducing fatigue.

Description

technical field [0001] The invention belongs to the technical field of fatigue state research, and in particular relates to a simulation method and system for rapidly inducing fatigue state based on audio-visual stimulation. Background technique [0002] Fatigue refers to a phenomenon of decreased labor ability caused by overwork, which is manifested in: decreased flexibility of movement, slow response, increased work error rate, decreased coordination, and accompanied by subjective feeling of fatigue and weakness. There are more and more serious consequences. For example, fatigue driving accounts for 17% of traffic accident deaths in China, accounting for a very high proportion of traffic accidents; Mechanism into research. [0003] Human receptors include vision, hearing, touch, taste and smell, among which the information obtained by human beings relying on vision and hearing accounts for 94% of the total information obtained. In this way, most daily fatigue is also fat...

Problems solved by technology

[0004] Most of the fatigue-inducing paradigms in existing studies use methods such as continuous high-speed driving for more than three hours, night-time sleep deprivation, and long-term execution of tasks combined with sleep deprivation, which are effective for studying the neural mechanisms under fatigue; however, from the perspective of cost From the perspective of time and time, these fatigue-inducing paradigms have certain requirements for the implementation environment, and are not universal for workers in related research fields.
