Dear all,

I'm sorry that this is a little bit off topic (not a question about user
interfaces)... I'm currently writing on my first paper - it will be
about a HMD based 3D geometric construction tool that can be used in
mathematic and geometry education. It's based on the "Studierstube", a
collaborative augmented reality system (we're using 2 HMDs and the
Personal Interaction Panel, a two-handed 3D interaction tool composed of
instrumented hand-help props – a pen and a pad equipped with position
and orientation trackers).
Anyway, I want to ask you if you know papers about 3D modeling VR
systems (using HMDs)?
Do you even know papers about such systems being used in education?
I couldn't find anything yet. I know about 3DM by Butterworth (1992)
which is a VR 3d modeling system but I don't know others and nothing
that has been used in education.

I want to publish in an educational oriented journal and maybe some of
you know papers with good evaluation studies proving that VR helps to
improve spatial abilities. I've found one from HITL by Osberg (1997).

It would be interesting to know which spatial abilities (they are
usually splitted in 5 components spatial perception, spatial
visualization, mental rotations, spatial relations and spatial
orientation) are especially trained in VR and if all of them can be
improved and if there are the same effects of VR on men and women (there
are sex related differences in spatial abilities).

thank you very much in advance,
Hannes
