在系统中提出以虚拟手指空间位姿代替实际力作用线方向上位移的计算和基于实际材料的虚拟力外推的方法。

Using virtual finger's position steading of real distance and extrapolation based on real material are also suggested in the system.

基于此力变形模型，利用DELTA手控器，进行了柔性物体接触变形以及实时虚拟力反馈的半物理仿真。

Using this model, the deformation of the virtual object was simulated, and synchronously the real-time virtual contact force was provided with DELTA haptic device.

文中也考虑了虚拟力的间接求解的简化计算法。

In addition the indirect method of determination of hyPothetic forces is also considered.

众多质心点在虚拟力作用下作扩散运动,逐步消除视频传感器网络中感知重叠区和盲区.

Multiple centroid points repel each other to eliminate the sensing overlapping regions and coverage holes.
