Amplifying spatial rotations in 3D interfaces

We have derived the generic equations for the zero-order control-display gain that allow for linear and non-linear amplification of spatial rotations in 3D user interfaces. Sample 3D interaction techniques have been implemented for 3D viewpoint control and object manipulation.
