A mental state detection system and method based on multi-physiological signal fusion

Abstract

The invention provides a mental state detection system and method based on multiple physiological signal fusion, and belongs to the field of digital signal processing and intelligent wearable equipment. The system comprises a brainwave collection unit, a physiological signal collection unit, a processor unit and a prompting and warning unit. According to the system, multiple physiological signals are fused, discriminant analysis is conducted on the different states of a person through the respective features of the physiological signals, and the expected classified recognition effect is achieved by virtue of a classifier model; relatively speaking, the defects of single physiological signal feature detection are overcome; according to the detection method based on the physiological signals such as the brainwaves, the heart rate and the pulse, long-term detection on the mental state under the natural state of a human body is achieved through implicit man-machine exchange on the condition that the normal life of the person is not intervened.

Description

technical field [0001] The invention belongs to the field of digital signal processing and wearable intelligent equipment, and specifically relates to a mental state detection system and method based on fusion of multiple physiological signals. Background technique [0002] With the development of human-computer interaction technology and wearable device technology, physiological signals are widely used in the design and evaluation of interaction. Studies have shown that human physiological signals can be used to distinguish mental state and stress, and in many fields based on this This kind of physiological signal detection method has gradually attracted the attention of researchers. These fields mainly include human-computer interaction, affective computing, and adaptive technology. [0003] At present, the detection of people's mental state mainly includes subjective detection and objective detection. Subjective testing is mainly carried out through subjective evaluation...
