Method and system of emotion prediction based on brain activities

Abstract

In a method of emotion prediction based on brain activities, a computing device storing a plurality of source model sets corresponding to a plurality of emotion observation periods is configured to perform the steps of: obtaining a plurality of to-be-analyzed brain activity signal data when a target subject faces an emotion inducing source during the emotion observation periods; for the to-be-analyzed brain activity signal data obtained during each emotion observation period, using the source model set corresponding to the emotion observation period to obtain a current emotion prediction result corresponding to the to-be-analyzed brain wave signal data based on the to-be-analyzed brain activity signal data; and obtaining a cross-temporal emotion prediction result corresponding to the emotion inducing source based on the current emotion prediction results.
