Another direction than you're heading, but this guy's work with
Live/midi foot controller/home built stand-up bowed "bass" might spark
some translatable ideas for a motion-capture based "invisible cello"
like I think you have in mind...

I think this will be fantastically difficult to sound decent, unless
you want a very simple and limited instrument. The range of different
strokes with the bow is extensive, and the complex combination of
speed /angle / force / distance from bridge would be irreproducibile.
Have you tried playing a bowed instrument? I think working out how to
do it without some bow technique knowledge would be hard. I suspect
either a real cello / electric cello or getting an EUB would be a far
superior option. If you want to make that wacky have effects on the
electric cello with some stomp boxes.

I was thinking of a physical model maybe. I've read once a PhD
of a guy modelling a classic guitar. Full of maths, differential equations
and so on. And some audio samples were provided. It sounded nice.
The guy is Grégoire Derveaux.
The PhD is at: http://www-rocq.inria.fr/macs/spip.php?article102
It's in french but there is:
http://www-rocq.inria.fr/macs/spip.php?article81
It is not realtime as far as I know.
There is also the work at CCRMA on Digital Waveguide Synthesis:
https://ccrma.stanford.edu/~jos/pasp/Digital_Waveguide_Bowed_String.html
https://ccrma.stanford.edu/~jos/pasp/Sound_Examples.html
So maybe there is room for some more or less nice artificial sound
of bowed instruments.
Obviously the poor controls I think about are not sufficient to have a
100% realistic sound and yes, play a real cello would be ideal. But I
feel in the mood to hack a bit with this little camera and I want kind
of cello sound for some music I have in the head. :-)
