It is possible that I may not use optical motion capture at all for my project.
OK, I probably will.
I am looking into using Shimmer sensors. They have software which syncs the sensors (accelerometers, gyro, et. al.) to each other AND to cameras. So I could have everyone wear one (ideally across back) & get ID & location THAT way. Then I can still get some rich motion data from the legs using the live video motion capture.
Or else, I just use all Shimmer motion sensors, but I'd actually like to avoid that. I don't want something bulky on their ankles.
I looked into some active and passive marker optical motion capture systems, but ultimately they were too rich for my blood & my department's (I'm in the arts!). They recommended at least 20 cameras to deal with the occlusion, and that's well. I can already tell you that 20 motion capture cameras of that caliber is out of my price range.
Anyways, the folks at Phase Space & Qualisys & APDM were particularly helpful, and I would recommend them highly if you have the funding.
PS. Not that anyone follows this blog, but I did finish my Variations V paper, and I have feedback for it. I am hoping to do the edits and publish it AFTER Buenos Aires. Possibly after my dissertation defense. After that I will probably also dinosaur more (and again -- yes I use dinosaur as a verb now, you would, too). Oh, AND! My! Dinosaur! Got! Accepted! Into! NIME! as! an! installation! in! London! UK! Crazy trip since I'll be in BsAs & Sharif (my partner in this dinosaur business) will be bring the dino, so I have to send it to him (across the country) before I leave.
