What do you think of the general concept of the reuse of adapted 2D interfaces in 3D applications? As examples, consider pull-down menus, dialog boxes, scroll bars, etc. I've done a good deal of work that includes such adapted interfaces, including menus, file pickers, and palettes in the Conceptual Design Space, menus on a tablet in the Virtual Venue, and a generalized pen&tablet interface with buttons and draggable icons in the Virtual Habitat. Also, Ivan has given us the Virtual Notepad, and Mark M. used 2D interfaces in ISAAC (others from the group?). Ian Angus and Henry Sowizral, then of Boeing, did some cool work in this area a few years ago, and Matthias Wloka at Brown did the Virtual Tricorder interface. What do people think are the advantages/disadvantages of such paradigms? Do they have a place in VEs? If so, can we systematically describe where they might be useful? What are the best ways to constrain the user's input to 2D? In what cases is it best to keep the interaction completely in 3 dimensions? There, that should stoke the fire a bit... :-) Doug -- Doug Bowman, Ph.D. Candidate College of Computing, GVU Center, Georgia Tech Room 388 CRB, (404) 894-5104 bowman@cc.gatech.edu http://www.cc.gatech.edu/gvu/people/Phd/Doug.Bowman/
