Like how the nograv of Fly is what you want to do, mostly, unless you are flying by aero, then of course there are other effects. Suppose you are flying and somebody turns gravity on? </p><p class=MsoNormal> </p><p class=MsoNormal>Also, please look for current x3d ‘name’ for interactions, like maybe hover is isOver and use of select rather than click. Some superset of x3d and html event inOut styles? </p><p class=MsoNormal>The important thing is that a competent input/output device must be able to describe itself as to its allowed data and interactions plus the author must be able to describe what is needed to make the show, maybe at various capability levels. Finally, the user must be able to tell what can be done and make some simple tests to observe the results of using various techniques with available tools. </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>X3d recommended optional use of the keyboard and provided keys and events (not normative). </p><p class=MsoNormal>However, for implementers there was enough behind it so that most users in 2006 could expect that best browsers would at least do that set of keys. Again, the purpose was not to stop or start anything, just to document some current best practices that were being done by the most interesting tools. </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>This challenge of creating usable abstractions for human user interaction using modern human interface arts was last documented by x3d around 2006, I think. I hope to see great advancements in documenting what will be regarded as World-class best practices for development of an important collection of x3d statements and sensor nodes to support the widest range of human input/output features. We need to get interaction data into the scene, out of the scene , interpreted by the user, then put back into the scene, etc.</p><p class=MsoNormal> </p><p class=MsoNormal>Thanks,</p><p
