System and method for detecting color perception based on electroencephalogram evoked potential

Abstract

The invention discloses a system and a method for detecting color perception based on electroencephalogram evoked potential. The system comprises a stimulation screen, an electroencephalogram extraction device, an electroencephalogram signal amplifier, an electroencephalogram signal collector, an electroencephalogram signal analysis module and a result output device. The stimulation screen is used for displaying a flash block with colors alternately changing at a certain frequency and applying visual stimulation to a testee. The electroencephalogram extraction device is used for extracting electroencephalogram signals of the testee after the testee receives the visual stimulation, and the extracted electroencephalogram signals are amplified by the electroencephalogram signal amplifier, transmitted to the electroencephalogram signal collector, collected, transmitted to the electroencephalogram signal analysis module, analyzed and then outputted by the result output device. According to the technical scheme, the color perception is objectively detected by the system and the method based on cross modulation components of the electroencephalogram evoked potential. The system is simple, convenient to operate, short in detection time and accurate in result.

Description

technical field [0001] The invention relates to the technical field of color perception ability detection, in particular to a color perception ability detection system and detection method based on EEG-evoked potentials. Background technique [0002] Humans vary widely in their ability to perceive color, but this variation cannot be determined by routine tests of eye function other than color perception. At present, most of the detection of color perception ability relies on the color chart method, which needs to be completed by physician-assisted detection and subjects' subjective reports. The detection by color chart method is highly subjective, and in many occasions, the use of this method is inconvenient or even unusable, and it cannot be quantified. Effective detection cannot be carried out in scenarios where the subjects cannot communicate with doctors, such as animal experiments, detection of infants, persons with intellectual disabilities, and autism. At the same t...

Problems solved by technology

The colorimetric method is highly subjective, and in many cases it is inconvenient or even unusable, and it cannot be quantified

Effective detection cannot be carried out in scenarios where the subjects cannot communicate with the physician, such as animal experiments, detection of infants, persons with intellectual disabilities, and autistic patients, etc.

At the same time, the subjects may also start from their own interests and use extreme means to falsely report the actual test results, which will cause hidden dangers to people's production and life.
