以家居布局为应用背景，采用双手交互的分工协作，结合2种不同维度的输入设备的特性改进3D地图技术和遥取技术，实现地图和场景的无缝融合以及远处物体的直接操作；增添场景约束语义，实现物体的成组移动,通过语义识别和反馈来实现场景布局的精确定位．

英文摘要：

In this paper, we introduce a new system based on two handed input, which can quickly furnish a room. Making reference to the characteristic of two input devices with different degrees of freedom, the system improves the 3D map and remote-object-selection technique, and obtains a seamless fusion between the map and the scene. It also helps users directly manipulating remote objects. The system uses constraints to restrict object motion in 3D scenes, which helps users easily move objects in a group. With these techniques, the system makes interaction much simpler and more intuitive.
