The 3D spatial-stereo effects of headphones can be quite striking.
Beware the blinders of Monitor-centrism.

David's assertions below, that 3D interfaces simply don't work, are
correct only when 3D representations are confined to small 2D spaces,
like the screen of a monitor.  The inability of the user to move around
and in some way tap his or her proprioceptive capabities -- the spatial
sense provided by sloshing fluid in the inner ear -- seriously limits
the value of 3D systems on desktops.

Similarly, since the biggest monitors are only in the 23" range, and we
sit at least two feet away (if we're playing it safe), until we go
wall-hanging screens (and better yet, immersion theaters), the subtended
field of view these images can provide is inadequate to fool the brain
into thinking it's "inside" an imaged space.

When (not if) we move to easily accessible immersion spaces like the
CAVE (and the Virtual Environment Theater, which my firm, Worldesign
Inc., pioneered), only cheaper and more plentiful, 3D interfaces will
start to make a great deal of sense.  But they'll be different from the
mnemonic and semantic allegories that currently pass for 3D interfaces.
Like natural language interfaces, natural perception interfaces will
process information the way we do, using the natural world as its model.

For some suggestive ideas, see http://www.fakespace.com/.  Fakespace and
its founder, Mark Bolas (who has a new design firm affiliated with the
original Fakespace), pioneered 3D interfaces.  Mark did some of his most
outstanding work, BTW, using simple vector graphics generated by
pre-Windows PCs and viewed through a wearable headset (NASA's first).
The elevator experience was remarkable.

Worldesign, my firm, evolved over time from a typical 3D design studio
(1992, a spinoff of the HIT Lab) to a GIS shop using 3D interfaces
(1995-6).  Our last "product" was an alpha version of a map-to-3D model
of neighborhoods, for utilities and others to use.  The ability to see
pipes and conduits underground (a serendipitous feature) wowed the
engineers.  Unfortunately, we had to close the doors before we could go
to beta (the decline of VR anticipated the dot-com catastrophe).

Finally, I note that Magic Earth, which provides a 3D interface for oil
exploration and development, was just sold to Halliburton for ~$100MM.
Someone must like 3D interfaces...!  (See http://www.magic-earth.com/.)

Thanks to Martin for raising the issue.
