METHOD FOR EVALUATING SOCIAL ENGAGEMENT USING ELECTROENCEPHALOGRAM AND SYSTEM APPLYING SAME

摘要

The present invention provides a method for evaluating social engagement using an electroencephalogram. Objective evaluation for controlling the psychological distortion of a user, which occurs in an evaluation process, is enabled by quantitatively evaluating social engagement with respect to an actual virtual object. The method according to the present invention can be used as a tool for three-dimensional model engineers, animation makers, artificial intelligence developers and remote-augmented reality system makers to objectively evaluate social engagement with respect to an object developed in the fields of game design, movie-making, character animations, etc. Usually a subjective psycho-physical scale method is used to evaluate social engagement felt by a user. But the traditional evaluation method cannot control the psychological distortion of the user, which occurs in the evaluation process, even if well-devised evaluation forms and questions are used. Also, concrete and logical grounds are not provided with respect to a methodology for evaluating social engagement and the validity verification of a measuring method is not sufficient. The present invention is very useful as a basic research for objectively evaluating social engagement with respect to a developed virtual object environment. The method for evaluating social engagement using an electroencephalogram comprises the steps of: measuring the brain waves of an examinee who is psychologically stimulated by an external stimulus; classifying the brain waves by band; analyzing at least one among the absolute power, relative power and spectral edge frequency of the brain waves for each band; determining increase or decrease in at least one among the perceptional element, emotional element and behavioral element of social engagement depending on the result of the analysis; and evaluating the social engagement of the examinee depending on the increase or decrease in the elements.;COPYRIGHT KIPO 2016
