多投影系统D-vision中双手6自由度力觉交互

Both-handed 6DOF Manipulation with Force Feedback for Multi-Projection D-vision System

D-vision系统(这里“D”有“DivideScreen”和“Duplex-Vision”双重含义)是一类基于PC机群的多投影虚拟现实系统(或简称多投影系统)。给出D-vision系统中双手6自由度力觉交互的实现过程:在客户端协同控制两个力觉交互设备Spidar-G(SpaceInterfaceforArtificialRealitywithGrip)实现双手协作交互,其次构造一个基于UDP的Socket类完成客户端和绘制服务器节点之间的通讯,传递跟踪球的位置、方向等信息;然后,通过分布绘制实现在大屏幕上无缝显示。最后实验结果表明:在D-vision系统中双手6自由度力觉交互是一种自然直观的人机交互方式。

The D-vision system means ＂Divide screen＂ and ＂Duplex-vision＂, which is one kind of multi-projection system for virtual reality based on PC cluster. The high immersion for vision is possible. Two-handed 6DOF manipulation in D-vision system was given： using two Spidar-G systems to client PC to realize the collaboration for both hands, constructing sockets based on UDP to communitate among the nodes for transferring the information of grip＇s position and orientation, and finally displaying the whole image on large screen by distributed parellel rendering. Also some experiments show that the haptic/force feedback via both-handed 6DOF manipulation is nature and intuitive interaction in D-vision system.
