Can I attach 2 PS moves to my feet, to track foot pitch/yaw/rotation. Would it track me standing on my tippy toes if I attached them to sides of shoes?
As vmaslov explained, PS Move can't be used for tracking feet in Mocap Studio. That said, iPi
should be able to track a performer standing on tippy toes. However, the bend will only be at the
ankle joint with no bend in the toe joints. You'll need to add that additional bend in your target animation program.
Also, if this is a long sustained pose, you'll probably want to constrain the feet for that range so it doesn't 'wiggle' noticeably. This should be done in your animation program too.

and for hands, I was going to follow a tutorial to make the ps moves into gloves.
Some users do that with success. I would try it without first just so you understand how the device works and what the strengths and limitations are. FWIW, I just hold the devices in my hands and it works fine. The advantage is that I can control mocap studio remotely this way. If you do decide to just hold the devices, the trick it to hold it firmly even as you rotate and bend your wrist. This doesn't mean you need to grip it tightly, you just need to keep it from rotating loosely in your palm--for accuracy, you want the device to record only the rotation of the
wrist and nothing more.

Now all thats left is tracking head/face. I was thinking instead of using ipisoft, I could simutaneously use an iphone attached to a helmet, and track my facial expressions/head movement, then combine the (body,hands,feet) tracking with (head,facial tracking) in Maya / Motion builder. Has anybody tried doing this? Do you think this would work well or would the data be out of sync somehow? There's alot of options of recording face/head data with iphone now.
To me, this sounds a bit ambitious, but if you can make it work, definitely share the results.
A more realistic setup (in my opinion,) is to use another PS move attached to the head to capture the head rotation, and then do the face and fingers capture in a separate pass. I'm not using face capture but I've been experimenting with hand/finger capture with another system using a Leap Motion device, with the intention of adding this motion to the iPi mocap data afterwards. (I haven't gotten quite that far with these tests yet.) You can do the same with face capture software.
For the head, I currently use a bicycle helmet with the PS Move device attached using a velcro strap and a small foam pad. This rig works great for head capture! If you do a search in this forum, you should be able to find a pic of this rig. Side note: I got a GoPro strap a while back to use for PS move head tracking rig but haven't tried it yet; for now, the bike helmet has been perfect.
Hope this helps.
