Thanks Matt for your important comment.

Of course there're plenty of applications that go well.
Basically, practicability much relies on the affinity between the user
interface and task requirements. 

For example, I think flight simulators are practical mainly because
input devices (control panels) are real objects. Perhaps it's also
because output devices available today are enough good for flight
simulators. I mean, in this case, exact reproduction of depth cues is
not essential so that cumbersome and imperfect devices for real-time
head-tracked stereoscopic view are needless.
