Claim 6:
7. The head-mounted VR device according to claim 1, wherein the user head 6DoF tracking module is configured to compute 6DoF tracking data of user's head in a 3D space in real time according to each frame of image data of the four first tracking cameras and in combination with inertial navigation data of the IMU sensor at current time;
predictively interpolate the 6DoF tracking data of the user's head in the 3D space at a current shooting frame rate to the same frame rate of the IMU sensor in real time in combination with the inertial navigation data of the IMU sensor at the current time; and
display and output the predictively interpolated 6DoF tracking data of the user's head in the 3D space at a frame rate greater than 75 Hz after application rendering.
