The movable plate 103 is hinged on the round table 201, so that the movable plate 103 can be rotated outward on the round table 201, and by starting the rotating motor 202, the rotating shaft 203 drives the collection assembly 300 to rotate in all directions, so that the collection device can collect facial expressions from multiple directions at the same position.

[0030] The collection component 300 also includes a shell 302 arranged on the rotating shaft 203, a frame 303 is arranged in the shell 302, a lens 301 is installed at the front end of the frame 303, a fixed shaft 304 is fixedly arranged at the rear end of the inner cavity of the frame 303, a vertical fixed block 304a is fixedly installed at one end of the fixed shaft 304, a sphere 305 is also arranged in the inner cavity of the frame 303, a vertical slide groove 305a and a horizontal slide groove 305b are opened on the sphere 305, and a first adjusting member 309 and a second adjusting member 3010 are arranged in the frame 303.

[0031] The vertical fixing block 304a is arranged on the vertical slide groove 305a, and the ball 305 moves on the vertical fixing block 304a through the vertical slide groove 305a. The vertical fixing block 304a is fixed on the fixed shaft 304. When the ball 305 moves, the ball 305 can be rotated up and down through the vertical slide groove 305a and the vertical fixing block 304a.

[0032] A transverse slider 306 is movably arranged in the transverse slot 305b, a fixing rod 307 is fixedly installed at the middle of the outer end of the transverse slider 306, and a camera 308 is installed at the other end of the fixing rod 307.

At this time, when the fixed rod 307 needs to move up and down, the ball 305 rotates on the vertical fixed block 304a through the vertical slide groove 305a, so that the camera 308 can move up and down. The second is to start the second micro motor 3010a so that the rotating shaft drives the first arc slide rod 309b to move up and down, thereby driving the fixed rod 307 to slide in the second arc slide rod 3010b. The shaft drives the second arc slide rod 3010b to move left and right, thereby driving the fixed rod 307 to slide in the first arc slide rod 309b. At this time, when the fixed rod 307 needs to move left and right, it drives the horizontal slider 306 to move along the horizontal slide groove 305b on the sphere 305, so that the camera 308 can move left and right. The third is to start the first micro motor 309a and the second micro motor 3010a at the same time to realize the above two activities, so that the camera 308 can move in multiple directions.

[0034] Example 2: S1. Setting the experimental scenario

[0035] The experimental situation was created by the method of field experiment. Multiple experimental subjects were randomly selected to observe and record the muscle expression samples of complex emotions generated in the experimental situation using the facial acquisition device. The FACS facial expression coding system software was used to record the samples and analyze the micro-expressions of the subjects. SPSS software was then used to perform descriptive statistics, classification comparison, and correlation analysis on the experimental results.

[0036] In order to avoid the adverse effects of the experiment on the experimental observation and analysis results when the subjects are already aware of the relevant content and situation of the experiment, as well as the mutual interference between the subjects, the experimental situation is simulated in a confidential and fully enclosed manner before the experiment. The subjects will be taken alone into a closed environment equipped with a facial expression acquisition device to watch classic sensational film and television clips. During this period, the facial expression acquisition device will record the changes in facial muscle expressions made by the subjects in the film and television clips. Since the closed and individual film-watching experimental situation is not limited by the influence and restrictions of other factors such as the surrounding environment and people, this experimental situation has a strong authenticity for the muscle expression of the subjects' real complex emotions.

[0037] S2. Sample selection

[0038] The randomly selected experimental subjects include people from both the Eastern and Western races. When selecting research subjects, attention should be paid to the control of other variables such as the subjects' physical and mental conditions, mental states, and intelligence levels, which can reduce unnecessary influences and ensure the accuracy of the comparative experiment.

[0039] S3. Research plan

[0040] S301. Expression of single emotion in facial muscles from the perspective of Eastern and Western cultures: 30 samples were randomly selected. All the test subjects were healthy, had no neurological diseases, and had normal intelligence and physical fitness. The 30 test subjects were brought to a closed environment and presented with images corresponding to six basic emotions (happiness, sadness, anger, disgust, surprise and fear). The facial expression acquisition device was used to record the micro-expression changes of each person when they had emotions, and the images were compared frame by frame. To ensure the scientific nature of the research, SPSS, a data analysis and statistical software, was used for processing and analysis to ensure the validity and scientific nature of the data analysis. This was done to verify Paul Ekman's conclusion that "facial expressions of different cultures under a single emotion have commonalities."

[0041] S302、Expression of complex emotions through facial muscles from the perspective of Eastern and Western cultures

[0042] S3021. Experimental preparation: This experiment is a comparative experiment, assuming that Eastern culture will affect people's facial muscle expression of complex emotions over time. The variables that need to be considered are: the age, physical and mental health status, cultural education level, and environmental culture of the test subjects. 100 subjects were randomly selected as experimental test samples to participate in the research experiment. A relatively closed environment with a mild atmosphere was selected, and a facial expression collection device was set up in the environment. Video tapes that can cause different emotional fluctuations in people were played in front of the test subjects;

[0043] S3022. Sample extraction: The test subjects were randomly assigned to the test order and brought into the test environment one by one for testing. In order to avoid the mutual influence of negative emotions, the test was divided into three groups (happiness + surprise, sadness + anger, disgust + fear) and the test was completed within 15 days. All facial expression changes of the test subjects during the period were recorded as experimental samples;

[0044] S3023, data analysis: playback the experimental video, and capture the facial expression photos of the test subjects during each complex emotional transition, import them into FACS learning software, compare and analyze each AU unit on the face, and distribute and compare the repeated expressions according to the probability ratio of the weights to draw experimental conclusions;

[0045] S3024. Conclusion Empirical Study: Apply the conclusions drawn to practice, try to observe other people's facial micro-expression activities during interrogation records and dispute mediation, to test the validity of the conclusions and find out the common muscle movements of Chinese people's facial expressions when they have complex emotions from the perspective of Eastern culture.

[0046] S303、Expression of complex emotions through facial muscles under the cultural differences between the East and the West

[0047] S3031. Experimental preparation: This experiment is a comparative experiment, comparing the differences in facial muscle expressions of complex emotions produced by test subjects in the same situation under the cultural differences between the East and the West. The variables that need to be considered are: the age of the test subjects, physical and mental health status, cultural education level, and degree of environmental and cultural influence. A total of 50 test subjects from Western countries and Westerners randomly selected on the street were used as experimental test samples to participate in the research experiment and form a sample comparison study with 50 Chinese test subjects. A relatively closed environment with a mild atmosphere was selected, and a facial expression collection device was set up in the environment. The same video tape that can cause different emotional fluctuations in people was played in front of the test subjects.

[0048] S3032. Sample extraction: The test subjects were randomly assigned to the test order and brought into the test environment one by one for testing. In order to avoid the mutual influence of negative emotions, the test was divided into three groups (happiness + surprise, sadness + anger, disgust + fear) and the test was completed within 15 days. All facial expression changes of the test subjects during the period were recorded as experimental samples.

[0049] S3033. Data analysis: Replay the experimental video and capture the facial expression photos of the test subjects during each complex emotion transition. Import them into FACS learning software, compare and analyze the various AU units on the face, and distribute and compare the repeated expressions according to the probability ratio of the weights to obtain an experimental report. Use SPSS software to compare and analyze the data with the experimental report on facial muscle expression of complex emotions under the influence of Eastern culture in the second phase, and draw the conclusions of the third phase of the experiment.
