I'm in process of putting togehter an overview of relevant immersive
modeling systems therefore I wonder how many systems are out there still
alive and kicking...

I'd like to focus on immersive systems assuming at least stereoscopic
view and tracking.
For a classification I've put together a number of criteria for
discussion, like:

- what is the area of application (conceptual or elaborative modeling,
sketching, etc.)?
- what is the average size of models?
- is the modeler fixed to a certain visualization system like HMD, Cave
or Workbench?
- what is the number of input options (one- or two-handed interaction,
gestures, required number of buttons, speech recognition)?
- what sort of input devices is used, providing how many DOF?
- is force feedback provided?
- which geometrical representation is used (discrete or continuous,
surface-, volume-, hybrid-representation)?
- direct or indirect generation and modification of geometry?
- number of functions for generation and modification of geometry?
- which interaction metaphors are used?
- which menue repräsentation is used?
- underlying VE-software system?

Is this it? And who will be willing to fill that in for her system ;-)
I'd be glad to share ideas...
