It's been a tick since we've heard any news on the 3D drawing front, but a number of computer scientists from Brown University are putting the art back in the proverbial foreground with its Drawing on Air installation. Put simply, users can slip on a virtual reality mask, grab a stylus and tracking device, and go to town. The system uses "drawing guidelines, force feedback, and two-handed interaction" to assist artists in drawing more precisely, and once movements are made, the patterns are transferred to a computer for use in 3D modeling and design programs. Unfortunately, such a system can't currently be priced at points which John and / or Jane Doe would be happy with, but the researchers did state that commercialization wasn't "too far away" and that prices should decrease from "thousands of dollars to hundreds of dollars in the next few years."
