The invention discloses a hand motion tracking method in a virtual driving environment, and the interaction with a virtual world is achieved through capturing the gesture data of a person in the realworld. In a virtual driving environment, steering wheel operation data of two hands of a user is captured through the real world, and is fed back to a driver model in the virtual world; the hand posture data captured by Leap Motion equipment can be seen in the virtual world in a natural two-hand operation mode like the real world through IK animation accurate calculation, so that the action simulation of the whole arm is realized, and the sense of reality and immersion of simulation experience are enhanced.
