Classification: CPC A  G | IPC A  G

Claim 1:
2. The method according to claim 1, wherein
the hand-motion tracker and the foot-motion tracker collect pose information of a hand motion and pose information of a foot motion in real time respectively by using a built-in electromagnetic sensor/ultrasonic sensor, and wirelessly transmit to an electromagnetic signal receiving module/ultrasonic signal receiving module of the head-mounted VR device by using an electromagnetic signal emitting module/ultrasonic signal emitting module;
the hand-motion tracker and the foot-motion tracker also collect IMU information of the hand motion and IMU information of the foot motion in real time respectively by using a built-in second IMU sensor, and wirelessly transmit to a first wireless-communication module of the head-mounted VR device by using a second wireless-communication module;
acquiring the 6DOF hand-motion data and 6DOF foot-motion data of the user comprises at least one of:
receiving hand pose information and hand IMU information sent by the hand-motion tracker, and fusing the hand pose information and the hand IMU information to obtain the 6DOF hand-motion data; or
receiving foot pose information and foot IMU information sent by the foot-motion tracker, fusing the foot pose information and the foot IMU information to obtain the 6DOF foot-motion data.
