Title:
EVALUATION DEVICE AND EVALUATION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/093168
Kind Code:
A1
Abstract:
This evaluation device is characterized by comprising: a brain wave acquisition unit for acquiring brain wave signals of multiple subjects acquired from the individual subjects; an intensity data generation unit for generating intensity data chronologically representing the relationship between the intensities of signal components in a predetermined frequency band or the intensities of signal components in multiple frequency bands on the basis of the brain wave signals; a correlation data generation unit for acquiring all combinations of two paired subjects from the multiple subjects, calculating a cross-correlation function coefficient of the intensity data of each pair at each time instance, and generating correlation data chronologically representing the cross-correlation function coefficient for each pair; and an output unit for generating evaluation data representing a value of a synchronous degree of brain wave variations of all the multiple subjects on the basis of the correlation data generated for all the pairs, and outputting the evaluation data.
