Embodiment Construction

[0039] An embodiment of the present invention will be further described below in conjunction with the accompanying drawings.

[0040] In the embodiment of the present invention, such as figure 1 As shown, a mental state detection system based on multi-physiological signal fusion, the system includes an EEG acquisition unit, a physiological signal acquisition unit, a processor unit and a prompt warning unit;

[0041] In the embodiment of the present invention, the EEG signal acquisition unit adopts the Emotiv Epoc, a portable EEG sensing system developed by EMOTIV Systems Company of the United States. This device uses a device that can measure EEG activity and is similar to an EEG to detect and Processes brain waves as well as facial muscle signals. The device collects EEG signals in a non-invasive way, and can measure various thoughts and emotional signals of the human body; in addition, the Emotiv Epoc helmet also integrates a gyroscope, which can control window images or mo...

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...
