Maybe when I will have finished to implement the GROUNDED/HORIZONTAL mode
you can give it a try and decide which  name best fits. In my concern I
clearly incline towars grounded as the implementation I was about to propose
allows step over small obstacles like stairs.

If you have remarks on the implementation so far, go ahead...

to sukender :
I didn't exacly get your remarks while I'm sure they are founded. Anyway I
think that when I wil have finished to code both mode, things will become
clearer for me and for you.

Get you informed as soon as the manipulator is ready.

> Havig both modes sounds a good idea. In that case,
"FirstPersonManipulator" seems fine for me. Just be sure to:

you got rounding errors that

(radians; as you can see in the
