[comp.sys.mac] 2D vs 3D debate

Some ideas concerning the Macintosh 2D or 3D interface debate...

The fundemental problem as I see it is that 2D interfaces make no distinction
betwen text and display regions, buttons, controls and typein regions.
The flat, planar layout of a 2D interface provides no cues regarding
control of the display.

For example, look at an alert box.  A button in an alert box looks for
all the world like an ordinary displayed peice of text.  Other than the
fact that it's shaped like a button it could be anything.

Now give that button a raised 3D look and it becomes rather clear that
it is a metaphorical object (a button) which is sitting ON TOP of a metaphorical
piece of paper (the laert box).  As such it is also something that you
can click on (depress).  So raised objects are typically controls like
scrollbars and buttons.

By putting text and graphics inside a lowered "window" of a panel you
are basically telling the user that this is a special part of the panel
which is used to display things.  Thus lowered regions are displayable
regions and typin regions.

3D look and feel is more than superficial glitz.  It serves a psychological
function.

One problem beginning users seem to have with the macintoh interfacte is
identifying and differentiating between things that can be chosen, dragged,
activated, edited, or any combination of the above.  Nothing intuitively
informs users that a desktop icon is more "dragable" than, say, a chooser
icon.  Perhaps mobile objects (icons, windows, tear off menus, etc.) should
look three dimensional, as John T. Nelson suggests.  But then there should
be a distinction made between things which are selectable only and things
which can be selected and dragged.  It is a complex set of combinations and
symbology which is too carved in stone.  I am sure that the Mac/Presentation
Manager/Windows/GEM/Workbench interface will eventually be replaced by a
simpler, more actively and animatedly graphic system that makes the Mac look
like MS-DOS.

The first two messages in this thread are elegant and powerful
arguments for the Mac interface going 3d!  I just hope someone at
Apple sees these postings (as folks at XXX@apple.com sometimes do).
I was dead-set against a change, but now you've sold me.
