A team of computer scientists at Brown University have developed technology that utilizes virtual reality tools to help design 3D objects that use motion to describe objects in the air.
A quote from the article at Discovery News:
The program, Drawing on Air, is meant to give scientists a better way to model complex ideas and could eventually allow doctors to visualize a surgical procedure before they ever cut into a patient. It could also give artists an intuitive, simple way for moving from traditional freehand methods to computers.
The technology provides users with a greater degree of control and precision in designing 3D models from the 3D perspective.
A quote from the article at Phyorg.com:
"If we can boost the precision with which scientists can interact with their 3D data using a computer, then many more scientific uses for virtual reality technology may become possible," said Daniel Keefe, who along with Robert Zeleznik, and David Laidlaw from Brown University presented 'Drawing on Air' in a recent issue of IEEE Transactions on Visualization and Computer Graphics.
The techniques are supposedly easy to learn and could certainly contribute to several scenarios where precise and easy to learn (ZDNet) virtual reality application are vital.
