1 results about "Heart rate analysis" patented technology

This invention relates to the field of emotion recognition technology, specifically to a method and system for emotion event recognition based on multimodal physiological parameters. The method determines a baseline time window based on the changing trend of the respiratory rate time series; it determines the heart rate analysis interval and blood pressure analysis interval based on the hysteresis response characteristics of the heart rate and blood pressure time series within the baseline time window; the baseline time window, heart rate, and blood pressure analysis intervals constitute the current representation feature; the feature matching degree is determined based on the similarity between the current representation feature and a preset set of historical representation features; the current representation feature is weighted and fused for optimization based on the feature matching degree to determine the optimized representation feature; the optimized representation feature is input into a pre-trained classification model, which outputs a category label corresponding to the emotional event. This makes the representation feature more closely resemble the real emotion-physiological linkage, so that the classification result can take into account the differences in individual physiological characteristics.
