Hi Ji-Young,
we conducted a study on a 3D immersive display that compares direct
manipulation and distance manipulation in terms of
user performance.
In direct manipulation, visual and manipulation spaces are superimposed.
In distance manipulation, there is an offset between visual and manipulation
spaces (3 cases studied : 20, 40 and 55 cm).

you can find it here : http://www-rocq.inria.fr/~paljic/IPT2002paper.pdf
(Title : "A study of distance of manipulation on the Responsive Workbench").

I hope this helps.

Alexis.
