Import the facial capture data into the VR development tool and combine it with the virtual character or environment. Adjust the rendering settings as needed to ensure that facial expressions and movements are reflected in the VR environment in real time and smoothly. The user tries to use facial expressions and movements to interact with virtual objects in the VR environment. Step 6: The second micro motor 510 drives the internal worm of the second worm gear assembly 511 to rotate, so that the internal worm of the second worm gear assembly 511 drives the second rotating shaft 59 to rotate, and the first rotating shaft 52 drives the base 55 to drive the cylinder shell 56 to rotate, and the micro electric push rods 514 on the left and right sides respectively extend and shorten the corresponding positions to rotate the roller frame 516 inside the second rotating seat 515, and the roller frame 516 drives the sleeve 517 in cooperation with the annular limiting groove 518, so that the sleeve 517 moves outward on the outer wall of the second rotating shaft 59, and the second connecting tongue 520 is The inner cavity of the first groove 512 moves outward, and the sleeve 517 drives the first connecting tongue 519 to insert into the inner cavity of the second groove 522. The second rotating shaft 59 drives the sleeve 517 in cooperation with the first groove 512 and the second connecting tongue 520, so that the sleeve 517 drives the inner side of the roller frame 516 to rotate in cooperation with the annular limiting groove 518. The sleeve 517 drives the third rotating shaft 521 at the corresponding position to rotate in cooperation with the first connecting tongue 519 and the second groove 522, so that the third rotating shaft 521 drives the second mounting frame 523 to drive the monitoring camera 524 to rotate to a specified angle direction; Step 7: The first micro motor 53 drives the internal worm of the first worm gear assembly 54 to rotate, so that the internal worm of the first worm gear assembly 54 drives the first rotating shaft 52 to rotate, and the first rotating shaft 52 drives the base 55 to drive the cylinder shell 56 to rotate, so that the cylinder shell 56 drives the monitoring cameras 524 on both sides to move circumferentially under the cooperation of the third rotating shaft 521 and the second mounting bracket 523 on both sides, and the monitoring cameras 524 monitor the external environment. When an outsider enters the user's activity area, the monitoring camera 524 sends an alarm signal to the control module 2, and the control module 2 reminds the user through the earphone 6; After the experience, exit the VR application and facial capture application in turn, turn off the connection between the phone and the computer, store the equipment properly, ask the experiencer about their feelings, collect feedback about the experience, and adjust the accuracy of facial capture, the stability of data transmission, and the smoothness of the VR experience based on the feedback.
