Abstract

The invention discloses a movie audience experience evaluation method based on human-computer interaction, which is characterized in that it comprises the following steps: taking a certain number of movie clip samples with different emotional content and playing them; collecting a certain number of movie clip samples watching the different emotional content The EEG signals of the audience of the movie clips; frequency domain analysis is performed on the collected EEG signals, and EEG responses in different frequency bands are extracted; the EEG responses are split into EEG segments of a certain duration; The audience response consistency of the different EEG characteristics of the electrical segment, and the consistency calculation result is used as a multivariate measurement index of consistency between groups; according to the multivariate measurement index, the parameters of the human-computer interaction experience state identification method are corrected; further, Audience The audience obtains the evaluation of the emotional experience state of the whole movie according to the characteristics of the dynamic change time course of the experience state identified during the whole process of playing the movie.

Description

technical field [0001] The invention relates to a method for evaluating movie audience experience based on human-computer interaction, and belongs to the technical field of human-computer interaction. Background technique [0002] Film is the crystallization of industry, technology and art, and it is one of the most common and popular entertainment activities for the masses. For filmmakers and movie audiences, the audience experience of a movie is a key factor for the success of a movie. At present, the mainstream film audience experience evaluation system mainly relies on interviews with audiences or questionnaire survey data.
