Can someone summarize the available options for position sensors?
I'm looking for something that would fit on a PowerGlove (to replace its old
ultrasound sensors), and I have to watch my budget.  I don't mind going the
home-built route, but I'd need complete info.

On a related note, has anyone successfully built their own magnetic position
sensors ala polhemus?  How exactly do they work?  Is there a lot of technology
in those li'l things?  I considered looking up the patent info, but haven't
had a chance to yet.  (If someone lives closer to a patent office, the number
is 4,737,794)

Thanks for the help.
