Design and implementation of distributed collaborative virtual assembly system with three-dimensional force feedback

摘要

A distributed collaborative virtual assembly system with three-dimensional force feedback is designed and constructed, which is mainly composed by a single server, two sets of display terminals and two Falcon 3D force feedback devices over a network connection, and we use technologies such as virtual assembly, distributed virtual simulation, touch interaction, and voice communication to implement multiplayer tactile collaborative product assembly. The paper presents a distributed haptic synchronization perception method, of which participants select the appropriate assembling parts by the force feedback device separately, and then control the parts to move in different directions, and control the movement speed of the parts, and adjust the movement route of parts in time. System can receive the joystick real-time data, and calculates the control parameters and synchronize output to the force feedback device, to control the device to produce the action, to complete the assembly of the virtual engine model within the limited time. Participants can not only feel the weight of the relevant assembly parts, and can also have the feeling of the collision impact force.
