The point of this was that games followed a progression here. They started out as being a special purpose device you had to go somewhere to use. Then there were dedicated machines you could buy for games (Intellivision, Nintendo). After that step, many people bought PCs because they were game machines plus a little something extra. And that in turn shaped off the shelf PCs because hardware makers were wooing the game machine market. So LBE might get 3D devices into people's home, it's just going to take awhile. >> - Entertainment - letting the guest step into an experience >> and be a part >> of the story >> - requires HMD or CAVE (no, desktop monitors >> are not immersive) >> - includes virtual tours > >another gimme.

An HMD version of Backdraft that I can experience in my own home (as opposed to going to Universal Studios) might be a good sell. Here's a hypothetical. Cameras are getting cheaper and cheaper, yes? Pick 5-6 locations at a football stadium. At each location, place enough cameras at different angles to get full coverage. Now write software that, given head tracking info and the camera streams, stitches together what the person would see with his head at that angle in that seat. Now balance the cost of that setup (PC, trackers, HMD, satellite dish) against 5 seasons of front row seats, plus associated travel costs. > >> - Design of special effects for movies >> - desktop, HMD, CAVE > >Are there any cases of HMDs and CAVES being used for SPFX? Not that I know of, but I was listing it as a potential use. Imagine setting up the whole scene and then letting the director decide which camera angle he wants by walking around the scene. >> - Stage / Set / Lighting prototyping (for lighting managers, >> directors, etc) >> - HMD (or CAVE?) > >careful....would prototyping be done well in an HMD, or evaluation? >I can certainly see a desktop unit being used for general layout and a >cave/HMD being used for seeing what it looked like from an immersive point >of view. Any unit can be used for layout. I was thinking more of evaluation - what the lighting people we've talked to really want to do is be able to sit down in any seat in the theater and see what the lighting looks like. >> - Fast prototyping of vehicles (ex. cars) >> - requires HMD + physical props >> - ex. quickly experiment with different >> dashboard layouts > >lots of haptic needed here. Thankfully foamcore is a hell of lot cheaper than electronics. =) Jeff
