I've personally tried a treadmill with handlebars.  Except for walking
in a straight line, it's quite awkward.  At least it was using the
interface we had, whereby you would virtually move in an arc if you
walked while the handlebars were off-center (much like a car drives).
It would probably have been a little better if there were a steering
wheel which determined _absolute_ direction (instead of relative).
The main problem was that delicate manuevering was very difficult
(just like parking a car in tight space is difficult), especially
since it was difficult (or perhaps impossible) to back up.

I've not tried a mouse (hampster) type ball, but I imagine it would be
far more natural, since you can easily turn and walk in any direction
you'd like.

That could be done easily enough, but it still wouldn't give you
natural walking.  I assume you still mean that you use a treadmill,
which means you can still only really walk forward.
