我觉得这是一个巨大的优势，能够获得工作平面的联系，从上方。

I feel that it be a huge advantage to be able to access the working plane linkages from the top.

构造了虚拟工作平面与垂直工作平面，解决了二维手势向三维手势的映射问题。

Horizontal_plane and vertical_plane are constructed to resolve the problem of space mapping from 2d to 3d.

如果只使用了ZOFF，工作平面被重新定义为平行于目前工作平面且偏移量为ZOFF。

If only ZOFF is used, the working plane will be redefined parallel to the present plane and offset by ZOFF.
