the tested person enters the claustrophobic cabin and lies on the hollow bed board in the inner cabin body, a feeding system is started to pour wood dust into the inner cabin body, and heart rate and skin electricity data Q2 of the tested person are collected in the whole process;
collecting saliva cortisol data P2 of a tested chip after the chip is poured;
the tested active report of the current stress degree is required by the bidirectional microphone, and a specific score capable of reflecting the current situation is selected to obtain a self-scoring score;
the main test is connected with a video camera in the inner cabin body through a monitoring display module, the facial expression and limb reaction of the main test are observed, and the stress degree of the tested main test is judged to obtain other evaluation scores;
the tested person comes out of the claustrophobic device, and saliva cortisol data P3 and heart rate and skin electricity data Q3 under the state that the tested person is calm are collected;
and (3) establishing a comprehensive recognition algorithm model, and evaluating the claustrophobia degree of the tested by using the acquired self-evaluation score, the acquired he-evaluation score, and saliva cortisol data, heart rate or skin electricity data which are respectively acquired by front measurement, middle measurement and rear measurement.
8. A multimodal evaluation method for simulating claustrophobia conditions according to claim 7, wherein the established comprehensive recognition algorithm model includes a mild claustrophobia recognition algorithm model, a moderate claustrophobia recognition algorithm model, and a severe claustrophobia recognition algorithm model;
the severe claustrophobia recognition algorithm model simultaneously meets the following conditions:
(1) claustrophobia he scores, the score is 8-10 points, and the severity is shown;
(2) claustrophobia self-scoring, 5 or 6 points, is very fear;
(3) in the salivary cortisol data P1, P2 and P3, the change rate of P2 is more than 50% compared with the average value of P1+ P2;
(4) in at least one parameter of the heart rate and the skin electricity, the change rate of Q2 is more than 50% compared with the average value of Q1 and Q3;
the mild claustrophobia recognition algorithm model simultaneously meets the following conditions:
(1) claustrophobia he scores, 0-3 points, as mild;
(2) claustrophobia self-scoring, 0 score or 1 score, is manifested as mild fear;
(3) in the salivary cortisol data P1, P2 and P3, the rate of change of P2 compared to the mean of p1+p2 is less than 20%;
(4) in at least one parameter of the heart rate and the skin electricity, the change rate of Q2 is lower than 20% compared with the average value of Q1 and Q3;
wherein, the moderate claustrophobia recognition algorithm model is a tested which does not accord with the mild and severe claustrophobia recognition algorithm model, and is evaluated as the moderate claustrophobia degree.
