Referring to Figure 1, Figure 2 and Figure 3, the use of the test is first described, which can be mainly divided into the following steps:

Step 81: Retrieve the rating scale. The doctor activates the test unit 74 through the operation device 6, and inputs a mental illness name corresponding to the patient, such as fear of phobia, to the servo device 7. The test unit 74 matches the disease database 72. A rating scale for the name of the mental illness, and the rating scale is displayed on the display device 5.

Step 82: Pass the virtual environment test. The doctor manipulates the operating device 6 to select a suitable rating scale, and the testing unit 74 applies each of the test questions of the selected rating scale one by one. When testing each test question, the test unit 74 compares the situation data corresponding to the test question from the object database 73, and transmits the situation data to the virtual reality device 1 for the patient. Feel.

Specifically, the test unit 74 can transmit a situational material that can create images and noises of a crowd of people to the virtual reality device 1 due to the virtual environment. The sense of presence can make the patient fully immersed in it, and can directly lead to the patient's anxiety, fear and panic.

Step 83: Issue a doctor's inquiry. When the patient feels the virtual environment, the doctor transmits the sound to the virtual reality device 1 through the sound collecting device 4 to inquire the patient. For example, the doctor can ask the patient according to the test question: "What you feel now is, option 1. Not nervous, option 2. slight tension, option 3. normal tension, option 4. very nervous?", and the virtual reality device 1 can display options 1 to 4 in the virtual environment based on the context data. In addition, the doctor may display the content of the inquiry in the virtual environment directly by the virtual reality device 1 without vocal inquiry, and is not limited to the embodiment.

Step 84: Receiving patient feedback: the patient can input the answer data through the input device 3 according to the perceived virtual environment and the doctor's inquiry, and the test unit 74 receives the answer data according to the test question and the received question. The answering data analyzes a degree of response. At the same time, the testing unit 74 also receives the physiological signal of the patient detected by the physiological detecting device 2, and outputs a physiological reaction degree to quantitatively analyze the physiological signal.

Specifically, if the patient feels quite uncomfortable with the virtual environment of the noisy crowd, the option panel 4 can be selected through the touch panel, the test unit 74 will select option 4 according to the answer data, and option 4 of the test question is Very nervous, analyzing the response level to 4 points, at the same time, the test unit 74 will also receive the detection by the physiological detection device 2 The patient's ECG signal is measured, and the patient's ECG signal is analyzed in the frequency domain, and the patient's physiological state is very nervous, and then the physiological response level is analyzed to be 4 points, thus completing a test question. Quiz. Next, return to step 82 for the next test question, and repeat steps 82 through 84 until the test questions of the rating scale are all completed.

Step 85: Analyze the extent of the condition. The evaluation unit 76 can analyze the degree of the condition according to the degree of physiological reaction and the degree of response obtained after the test questions are measured. Specifically, the test questions can be divided into three groups of test questions according to three pressure sources: a crowded person, a tunnel and a closed bedroom, and the evaluation unit 76 can add a total for the test group to calculate the patient's participation in the crowd. The degree of disease is 10 points, the degree of disease in the tunnel is 8 points, and the degree of disease in the closed bedroom is 5 points, and the degree of the condition is displayed on the display device 5, so that the doctor can quickly understand the suffering of the patient. Severity, and doctors can also record the extent of the above conditions as a study, or compare with the degree of disease obtained in the future test to see if the treatment is effective.

Referring to Figures 1, 2 and 4, the following describes the use of the treatment, which can be mainly divided into the following steps:

Step 91: Retrieve the treatment list. The doctor activates the treatment unit 75 through the operation device 6, and inputs a mental illness name corresponding to the patient, such as fear of phobia, to the servo device 7, and the treatment unit 75 matches the disease database 72. a treatment list of mental illness names, and the treatment tables are displayed on the display device 5, For example, the treatment tables may be a treatment table for a closed bedroom, a treatment table for a tunnel, and a treatment list for a crowded person.

Step 92: Treatment through a virtual environment. The doctor controls the operating device 6 according to the degree of the condition tested by the patient to select a suitable treatment table, and the treatment unit 75 will treat each training question of the selected treatment table one by one. When each training question is applied, the treatment unit 75 compares the situation data corresponding to the training question from the object database 73, and transmits the situation data to the virtual reality device 1 for the patient to feel .

Specifically, since the patient has a low degree of condition in the closed bedroom, the doctor may first select a treatment table for the closed bedroom to perform the treatment, and the treatment unit 75 transmits a training question when the selected treatment table is selected. The contextual information of the image of the closed bedroom is established to the virtual reality device 1, and the presence of the virtual environment can expose the patient to the virtual environment to achieve the effect of the exposure therapy.

Step 93: Issue a doctor's guide. When the patient feels the virtual environment, the doctor transmits the sound to the virtual reality device 1 through the sound pickup device 4 to guide the patient to relax, such as guiding the rhythm of the patient's breathing, or guiding the patient to view the virtual reality. Then, returning to step 92 for the next training question, and repeating steps 92 to 93, when the test questions of the selected rating scale are all treated, the doctor can control the operating device 6 to click on the tunnel. The treatment table inside, and after the treatment of the training questions for the treatment table in the tunnel is completed, the operation device 6 is operated to point to the treatment of crowded people. The treatment table, in order to let the patient gradually face the scene of more fear, so that it can achieve gradual progress, and gradually relieve the anxiety of the patient in a layered and divided manner.

It is worth mentioning that during the course of treatment or testing, if the patient is too anxious or nervous, and the degree of physiological reaction analyzed by the evaluation unit 76 is greater than the specific threshold, the evaluation unit 76 will drive the test. Unit 74 stops the test or drives the treatment unit 75 to stop treatment, thereby achieving the effect of automatically protecting the patient.

In summary, the virtual reality system of the psychological clinical application of the present invention can facilitate the doctor when the doctor evaluates the patient through the matching design of the servo device 7, the virtual reality device 1 and the physiological detecting device 2. According to the patient's mental illness name, the corresponding rating scale is retrieved, and the virtual environment of the three-dimensional space can be simulated to provide a better sense of presence for the patient to more directly stimulate the patient, and finally calculate according to the physiological signal of the patient. The degree of the patient's condition; in addition, when the doctor treats the patient, it is also convenient for the doctor to retrieve the corresponding treatment form according to the patient's mental illness name, and can simulate the virtual environment of the three-dimensional space to better achieve the exposure therapy. effect. In addition, during the process of performing the treatment or the test, the servo device 7 can also monitor the physiological signal of the patient at any time through the physiological detecting device 2, and automatically stop the test or treatment when the patient is too anxious or nervous, so as to improve the safety of use.
