Body location vs head/hmd location?

That is one advantage rift might have over vive actually. Since Rift is sensing from the 2 cameras, an arbitrary number of additional markers could be added to detect and track.

In theory. Although each LED needs to flash out an id number and there's a limited number of valid ids (not all codes can be used, for example numbers with a large number of off bits in a row would lag the tracking because it won't see the LED for a few updates).


Unfortunately head tracking alone can't tell you anything about body pose below the neck. You could guess, but getting it wrong would probably look worse than having no body. In games with a seated protagonist it's not so hard (flight sims, driving, etc), but in standing games there's just too many possible body poses for a given head position.

There's a few options:
- kinect 2 (slower update rate than rift, has trouble with feet and people facing away from the camera, but could work)
- perception neuron (full body mocap suit. Not very common and seems to have near zero support in games, but it works pretty well. Wireless and has up to 32 sensors on your body.
- Stem (if they ever release the damn thing. With 5 sensors you can do head, hands and feet (need head to sync rift tracking to stem tracking))
