- I don't want to be discouraging (sp?) but you won't get TOO far with
- $70,000. I think your better bet would be a couple of 486 with
- Sense8's system, if you want a ready-to-use system, or a low cost
- Indigo, but equipped with a hardware graphics engine, and program
- everything by yourself.
-
- 1. Helmet ~$6-7,000
-
- 2. Tracking systems:
-
- mechanical (adl-1) $1,500
- ultrasounds (logitech) ~$1,000
- magnetic (polhemus or bird) ~$3,300
- polhemus fastrak ~$5,500
-
- 3. Glove (cyberglove) $6,500 each (without tracking system)
-
- Each glove needs a tracking system too. If you have a fastrak, it's only
- $750 (or $500?) for additional sensor, otherwise buy from scratch.
-
- 4. 3D Sound
-
- Focal Point $1,500 (1 channel)
- Convolvotron $15,000 (4 channels, with reflection)
- Beachtron ~$3,000 (not sure)
- Acustetron TOO MUCH (maybe >$20,000)
-
- A basic configuration (1 helmet, 1 glove w/ magnetic trackers, a low
- cost 3D audio) is about $22,000. And you don't have the CPU and the
- software, yet.
-
- I think you should turn toward a network/parallel Sense8 system: two
- 486 (parallel option) for one person, plus the network code, to share
- worlds between 2 or more.
-
- Hope this helps,
