Will most 3D UI's be created on the desktop (Fishtank VR or even non-head tracked), in CAVEs, or using HMDs? Personally, I'm leaning more and more toward a mini-CAVE (which I believe someone nicknamed COVEs awhile back - anyone have a ref handy on this?). Sit the user down and then project onto both the table and wall in front of him. Or stick him in a corner and project on 2 walls. I think that until HMDs become a lot smaller and lighter (and maybe not even then?) working unencumbered has a lot more appeal (and better display technologies). The drawback of a full CAVE is that you have to work in a special room, and you lose some of the nice physical affordances you get from sitting at a desk. Although for entertainment applications, one of the things we learned from DisneyQuest is that you can't beat the drawing power of an HMD (novelty factor) for the common man. A CAVE is just a big theater with surrounding screens, sort of like a small OMNIMAX. Jeff
