There are enough formal & informal user studies and examples of compelling systems out there now that it would be foolish not to. I actually believe that Polhemus should not allow you to buy just one tracker, they should be sold in bundles of 2 only. :) If you are using desktop devices like the Spaceball, the advantages of 2 hands are not as clear, but may be worth trying. For example, I'm aware of one interesting project that used a spaceball with the left hand to orient objects, and a mouse with the right to pick vertices, etc. I've published a number of papers on 2-handed and 3D input techniques, which will point you to most of the interesting literature (at least as of 2 yrs ago). http://research.microsoft.com/Users/kenh/. I think Chris Shaw is the best guy to talk to about the modelling application, as he's done quite a bit of work in this area.

I thought it would be nice to join in again with a new topic.... 'What is your opinion on one-handed versus two-handed manipulation techniques, NOT only with respect to selection techniques?' I ask this question because we (my group) just started developing a new VR modeler - our old modelers used mainly one-handed techniques, and I am trying to convince my collegues to go two-handed. I know several of you have (including Chris and Jeff) have their opinion about the subject.... -Ernst -- ......... Dipl.-Drs. Ernst Kruijff ......... Ernst.Kruijff@archit.uni-weimar.de .........
