A Layout System by Two Handed Manipulation Based on Constraints

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.
