It does from a usability perspective, and this is what user interfaces
are about. For example, if you want to fix a photograph on a sheet of
paper, do you move the photograph with your hand or do you have buttons
and menus built into your desk that you can press and that, in effect,
will arrange for a robot to fetch the photo and move it to some place
on the sheet of paper lying in front of you? 

Direct manipulation is the obvious way.
