Real-time grabbing method of virtual hand based on data glove and physical engine

Abstract

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.

Description

technical field [0001] The present invention relates to a real-time grasping method of a virtual hand based on a data glove and a physical engine, in particular to a driving of a real-time virtual hand based on a data glove and a virtual hand based on a data glove, a position tracker, and a physical engine in the field of virtual reality.
