I am unaware of any standards. SGI had a 3D UI guide that was part of their
product docs, but it was really just a style guide.
Frankly, I think its too early for standards since
there is still so much room for improvement in 3D widgets. Even though all of
the commercial desktop 3D packages have similar interactions for various
operations (camera orbit, object rotation, etc.), users are still forwarding
plenty of complaints and wishes regarding fundamentals of the widgets. I work
on UI for 3ds max and regularly discuss these issues with hundreds of artists
and designers who use the interactions all day, every day - they would hate to
hear that we're done designing the gizmos.
The virtual trackball is a good example since it seems like one of the best
candidates for a standard. But when we gave one for the first time to max
users, many artists had problems with the traditional implementation - many
wished for a linear relationship between pixel-distance dragged and degrees
rotated (see http://www.vizmo.com/rgizmo.html). It might even be wise to
abandon the trackball and switch to a lever metaphor since the trackball does
work well when the pivot is off screen (not unusual in animation scenarios).
There is a similar story for each of the other widgets. With more
degrees-of-freedom comes more design choices and we're bound to have made a lot
of mistakes thus far.

Hi all, I'm currently looking for the existence of standards in the VE/VR
field.
Is there such a thing as a VR standard?
I interested in hardware standards as well as software ones. Specifically,
on the software side, is there any standard yet? Agreed, we have OpenGL,
but
this standard is not directly related to VR. I'm talking about
higher-level
standards for user interface and user interaction (IT's). Things like
standard 3D UI toolkits libraries for VR.
Any info / remark / thoughts will be greatly appreciated.
