Interaction techniques for a virtual workspace
Precise, dextrous work on spatial data requires a natural interface paradigm, and interaction techniques that allow for efficient work for hours on end. We present the interaction scheme we use for medical work, based on the reach-in hand immersion environment of the Virtual Workbench. The scheme uses an straightforward 'reach in with a hand-held stylus' metaphor and combines tool selectors which become active when approached, and tools which act on objects they approach, to make an easily learned, powerful interface in which the user can achieve productive work. Predictable behaviour by selectors and manipulators, at locations real to both hand and eye, produces a robust environment in which substantive work can be comfortably performed.
