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.
