Integrated Rotation and Translation for 3D Manipulation on Multi-Touch Interactive Surfaces

摘要

In the domain of 2D graphical applications multi-touch input is already quite well understood and smoothly integrated translation and rotation of objects widely accepted as a standard interaction technique. However, in 3D VR, modeling, or animation applications, there are no such generally accepted interaction techniques for multi-touch displays featuring the same smooth and fluid interaction style. In this paper we present two novel techniques for integrated 6 degrees of freedom object manipulation on multi-touch displays. They are designed to transfer the smooth 2D interaction properties provided by multi-touch input to the 3D domain. One makes separation of rotation and translation easier, while the other strives for maximum integration of rotation and translation. We present a first user study showing that while both techniques can be used successfully for unimanual and bimanual integrated 3D rotation and translation, the more integrated technique is faster and easier to use.
