An object oriented model of behavior encoded virtual tools

We propose a model of attribute laden virtual tools to aid manipulation, interaction and navigation in a virtual manufacturing environment for controlling robots and machines. Fundamental to the concept of using such virtual tools, and other object-oriented virtual entities of this type generally (e.g. virtual obstacles, virtual workpieces, virtual machines etc.), is that each virtual entity represents both the graphical representation, and other physical plus "intellectual" attributes of the real entity. The aim of the virtual tool concept is to create the next generation of interface which will solve problems associated with multiple hierarchies of menu, information and other tasks such as interaction, and manipulation associated with cyberspace.
