Problems solved by technology

Emotional bandwidth can describe emotional changes. If the mood is low and the sense of happiness is lacking, the bandwidth of positive emotions will be significantly narrowed, resulting in a narrower range of emotional changes. The emotional experience induced by external positive emotional information stimulation is insufficient, resulting in a sense of pleasure Depression, depression and other mood disorders

Abstract

Provided are a method and system for determining emotion bandwidths. The method comprises the following steps: generating a plurality of positive emotion pictures, neutral emotion pictures and negative emotion pictures, and respectively providing the positive emotion pictures, the neutral emotion pictures and the negative emotion pictures for a subject to view; respectively acquiring view point quantities of the positive emotion pictures, the neutral emotion pictures and the negative emotion pictures viewed by the subject and the left pupil diameter and the right pupil diameter for each view point; respectively calculating the pupil diameters for each view point and pupil diameter average values for the positive emotion pictures, the neutral emotion pictures and the negative emotion pictures viewed by the subject according to the view point quantities and the left pupil diameter and the right pupil diameter for each view point; respectively calculating a positive emotion bandwidth, a negative emotion bandwidth and a positive and negative emotion bandwidth according to the pupil diameter average values for the positive emotion pictures, the neutral emotion pictures and the negative emotion pictures viewed. By means of the method for determining emotion bandwidths, the physical index of pupil diameters is utilized to measure the magnitudes and ranges of positive emotion experience and negative emotion experience objectively, and the objective standard of the emotion experience is provided.

Description

technical field [0001] The invention relates to the technical fields of cognitive science and cognitive psychology, image processing and statistical computing, in particular to an emotional bandwidth measurement method and an emotional bandwidth measurement system. Background technique [0002] Existing emotion recognition technology, such as emotion recognition based on voice and face, mainly recognizes different types of emotions, such as the recognition of emotions such as happiness, sadness, and fear, and for the same type of emotion recognition, such as the degree of happiness (very happy, Relatively happy, etc.) or the lack of identification and quantification of the range of happiness. [0003] In the field of cognitive psychology, emotional experience is measured by presenting pictures of different types of emotions to subjects. Among them, the pleasure dimension of the picture is set from 1 to 9, a total of 9 pleasure levels, 9 is the most pleasant, and 1 is the le...
