Cognitive competence evaluation system and method based on eye movement and electroencephalogram characteristics

Abstract

The present invention discloses a cognitive competence evaluation system and method based on eye movement and electroencephalogram characteristics. The system comprises an experiment scheme design module, an experiment scheme display device, an eye movement acquisition device, an electroencephalogram acquisition device, a data storage module, an eye movement analysis module, an electroencephalogram analysis module and a scheme evaluation module, a tested person wears the experiment scheme display device, and an evaluation experiment scheme is played on a display screen for the tested person tocheck; the eye movement acquisition device and the electroencephalogram acquisition device are used for respectively recording related sight parameters and electroencephalogram parameters of the tested person in a presentation process of the evaluation experiment scheme, and model construction and ability evaluation on the eye movement parameters and the electroencephalogram parameters are conducted; analysis results of the eye movement parameters and the electroencephalogram parameters are stored in the data storage module; and a cognitive evaluation score is obtained through the scheme evaluation module, the cognitive evaluation score is displayed externally, the cognitive ability is objectively evaluated by adopting the eye movement parameter characteristics and electroencephalogram parameters in an experimental paradigm, and accuracy is obviously improved.

Description

technical field [0001] The invention relates to the technical field of objective evaluation of cognitive ability, in particular to a cognitive ability evaluation system and method based on eye movement and electroencephalogram characteristics. Background technique [0002] With the acceleration of the aging process of Chinese society, there is an explosive growth of brain diseases in my country, and cognitive impairment is one of the main manifestations of brain diseases. [0003] Taking Alzheimer's disease as an example, as of 2015, the number of dementia patients in the world has reached 46.8 million, of which 50%-75% are Alzheimer's disease (also commonly known as Alzheimer's disease). Every year, there will be 9.9 million new dementia patients worldwide, an average of 1 new person every 3 seconds. On the basis of the aging of the social population, my country has become a hardest hit area for Alzheimer's disease. At present, the number of Alzheimer's patients in China r...
