In this paper, we discuss the modeling of three basic ways of 3-D manipulation, in the context of a logical hand device and the Virtual Panel Architecture of our work. The logical hand device is a useful software abstraction representing hands in virtual environments. The Virtual Panel Architecture is the 3-D counterpart of the 2-D window systems. Both of the abstractions are intended to form the foundation for adaptable 3-D manipulation.
Within our software framework, the click-and-drag in 2-D graphical user interface can be gracefully replaced by a meaningful hold-and-move in virtual environments. With these tailorable abstraction tools, the semantics of natural and precise gestures can be rapidly prototyped.
