b. data acquisition in the experience process, wherein when a user interacts with a virtual reality human-computer, physiological characteristic data of the user at the moment is acquired;
c. data analysis, namely comparing and analyzing data in the user experience process with data in the natural state of the user;
d. and matching the level data, and matching the interactive data of the corresponding level for the user by the virtual reality computer according to the data analysis result.
2. The computer data acquisition method for virtual reality of claim 1, wherein the physiological characteristic data comprises body resistance data and heart rate data.
3. The computer data acquisition method for virtual reality according to claim 1, wherein in data analysis, noise reduction processing is firstly performed on data, irrelevant variables are removed, and the accuracy of data analysis is improved.
4. The computer data acquisition method for virtual reality according to claim 2, wherein the heart rate data is data for determining the heart rate of the human body by detecting data of specific wavelength of finger tip through a heart rate detection sensor.
5. The method as claimed in claim 1, wherein in the data analysis, the analyzed result is first compared with a preset safety threshold, if the analyzed result is higher than the safety threshold, the human-computer interaction is stopped, and if the analyzed result is lower than the safety threshold, the human-computer interaction is continued.
6. A computer data acquisition method for virtual reality according to claim 2, wherein the physiological characteristic data further comprises a jitter value of the user's finger under tension.
7. The method as claimed in claim 6, wherein the virtual reality computer stores different levels of data blocks, and the virtual reality computer matches the corresponding levels of data blocks according to the jitter value and the heart rate data.
