The invention discloses a real-time grabbing method of a virtual hand based on a data glove and a physical engine. The real-time grabbing method comprises five steps: first, starting a computer, the data glove and a position tracker; second, wearing the data glove, and operating the computer to acquire the data transmitted by the data glove and the position tracker; third, wearing the data glove to bend fingers and translate and rotate a palm, transmitting the positions and the change data of the fingers and the palm to a program by using the data glove and the position tracker, and driving the fingers and the palm to move by the program according to the received data; fourth, simulating a gabbing action to control the virtual hand in the computer to grab an object in reality by using the hand using the data glove, judging whether the virtual object is in a grabbed state by the program, if the object is not grabbed, returning to the third step and continuing performing the third step and the fourth step until the program exits, and if the object is grabbed, performing a fifth step; fifth, controlling the position and the posture change of the virtual object by calculating the position and the posture change of the virtual hand so as to control the movement and the rotation of the virtual object.

An acoustic field may be produced from a transducer array having known relative positions and orientations In this acoustic field, one or more control points may be defined. An amplitude may be assigned to the control point. Mid-air haptic effect for a virtual object on a human body part may be generated by moving the control point in a single closed curve comprising a plurality of curve segments. The single closed curve traverses at least one location where the human body part intersects with the virtual object. Additionally, a user may interact with virtual three-dimensional content using the user's hands while a tracking system monitoring the user's hands, a physics engine updates the properties of the virtual three-dimensional content and a haptic feedback system provides haptic information to the user.

The invention discloses a role control method, which comprises the steps of obtaining first state information of a target role at a first moment, the target role comprising M joints, and the first state information being used for representing information of the M joints; based on the first state information, first action information of the target role at a second moment is obtained through a stateprediction model, and the first action information is used for representing information of (M-1) joints; a first moment is obtained according to the first action information, and the first moment comprises the moment of each joint in (M-1) joints at the second moment; and controlling the target role to execute the first action through the physical engine based on the first moment. The invention further discloses a model training method. The moment acting on each joint of the role can be calculated according to the action information, and then the role is controlled based on the moment in thephysical engine, so that the vivid action sequence is generated, and the action effect of the role is improved.
