The invention discloses a method for detecting a fatigue state based on a multi-modal data fusion technology, and the method comprises the following steps: S1, collecting multi-modal training data through a sleep deprivation experiment, and carrying out the training of a model. Comprising fNIRS, ECG, PPG, GSP and Resp, hemoglobin concentration data, obtained through a fNIRS headband, of the forehead lobe of the brain is obviously related to fatigue, data of electrocardio, pulse waves, skin electricity and respiratory waves are obtained through an electrocardio sensor (pectoral girdle), a PPG bracelet, a GSR ring and a respiratory wave (Resp) sensor (waistband), the data collected by different devices are objective, the defects of psychological experiment methods are effectively overcome, and the psychological experiment accuracy is improved. And different modalities can provide complementary information, and even capture the features of the target from multiple angles.

The invention discloses a psychological experiment task-oriented subject response data modeling method and system, and belongs to the technical field of psychological experiment task data modeling, and the method comprises the following steps: collecting subject response data; performing reaction flow serialization, converting original data into a continuous time sequence, and recognizing a cognitive state transition point through a multi-scale recursive segmentation method based on dynamic entropy perception; dynamic cognitive model construction: adopting an improved drift diffusion model combining dynamic parameter decomposition and hierarchical Bayesian inference to obtain a dynamic cognitive analysis model reflecting cognitive strategy switching, fatigue accumulation and learning effect; and reaction data modeling: establishing a causal relationship among a state label, a cognitive parameter and a reaction behavior, and realizing quantitative modeling and prediction of a psychological experiment task. According to the scheme, fine modeling and dynamic analysis of the multi-dimensional psychological reaction process can be realized, and the interpretability and the application value of psychological experiment data are improved.

This application provides a data acquisition system for psychological experiments, relating to the field of data acquisition technology. The system includes: a wristband module for wearing on a target object to collect physiological and motion state data of the target object during a psychological experiment; a gateway module communicatively connected to the wristband module; and a central control module communicatively connected to the gateway module to receive and process data forwarded by the gateway module. The wristband module includes: a main control unit; a physiological parameter acquisition unit for collecting physiological data of the target object during the psychological experiment; a motion state acquisition unit for collecting motion state data of the target object during the psychological experiment; a first communication unit connected to the main control unit for sending the collected data to the gateway module; and a touchscreen for displaying a psychological experiment answering interface and an emotional state feedback interface to assist the target object in completing questionnaire selections and providing emotional state feedback.

The invention discloses a park green space optimization method based on plant community color quantification and emotion recovery influence, which comprises the following steps: collecting typical urban park plant community images through field investigation, and objectively quantifying plant colors by using image processing software; in combination with a psychological experiment normal form, after standardized pressure stimulation is applied to a subject in a laboratory environment, color combination plant community images with different proportions are presented; subjective psychological scale data and objective physiological electroencephalogram indexes are synchronously collected, the influence of different color composition proportions on the emotion recovery effect is obtained, and an optimal plant community configuration scheme is determined. The method fuses subjective and objective data, is high in quantifiability and operability, fills up the research blank of group scale plant community color quantization and an emotional response mechanism, can provide reference for plant community configuration design, is beneficial for realizing scientific planning of restorative landscapes such as park green land, and has a wide application prospect. And the design quality of the park green land plant landscape and the functionality of the park green land plant landscape are improved.
