I don't know what the latest is on integration of LifeForms with motion
capture / data acquisition systems is (Thecla?), but it sounds as though
any number of motion capture or gait analysis systems would do what Dr
Westreich is seeking.

There are a number of systems which use high-speed cameras and "markers" on
the body, which can also analyse the data. e.g. Selspot, Coda mpx30.

Hmm. Not sure about this, but it sounds like a CGI problem rather than one
inherently a part of the acquisition process.

Mathematical modelling software might do this, if one could import the data.

Sounds as if an almightily expensive motion capture system and several
pieces of software are required. I can't day much more than this, since
gait analysis is not my thing, and, even while doing my Masters, I didn't
have a hop ein hell of getting my hands on a high-end motion capture
