Summary
Deering describes a system that uses a 3D mouse, stereo CRT, and head/eye tracking to create a system capable of drawing in three dimensions and being able to view the objects in three dimensions by just moving the head around. The 3D mouse has a digitizer rod attached to it, acting as a wand that is used to draw and manipulate in 3D. Different button/keyboard combinations can be used to change the modality of the drawing program. The user can pull up a 3D context menu to perform different drawing and editing actions, including the drawing of many 3D primitives, drawing operations like coloring, moving, selecting, resizing, and even setting up animations. Their system is accurate enough in its 3D rendering that a physical ruler can be held to the projected image and be accurate.
There are no algorithms or true implementation details presented in this paper, so I don't feel the need to do much summarization. You draw in 3D with a 3D mouse with a 'wand' poking out of it, much like you would in any 2D paint program. You look at the object in true 3D thanks to stereoscopic display and head/eye tracking.
Discussion
I was fairly impressed with this, especially the accuracy in 3D rendering that was obtained. I'd like to see what could be done with this now with modern hardware. Especially with a truly wireless pen, for unconstrained 3D movement. Or even different pens for doing different things, so as to reduce button clutter and complexity. I think this could be a super killer app, especially with sketch recognition capabilities! Or turning the stereo CRT (they have stereo LCD, btw) into wearable glasses for more of a HUD approach--augmented reality.
I bet Josh P. drooled over this paper when he read it. But other than that, since there isn't an algorithm or anything besides interface information, I don't think I have much more to say that's really that useful.

There wasn't as much slobber as you'd expect, mainly due to the lack of time in presentation. But it was mainly a cool interface paper that showed some haptics/VR algorithms.
