From the website that I found this item on...
"AR-media Plug-in technology allows users to bring their models from the 3D modeling tool by Google into "reality."
Once installed and configured the plug-in allows users to visualize any model (textured or not) in Augmented Reality and experience a new way to interact with their digital content and show it to their customers, colleagues and partners. With AR Plug-in, Google Sketch-Up users are allowed to visualize their 3D models directly in the real physical space that surrounds them.
Through AR Plug-in, Sketch-Up 3D models can be visualized out of the digital workspace directly on users' desktop, by connecting a simple webcam and by printing a suitable code. The plug-in provides users with a visualization functionality that serves two main purposes: 1) study and analyze scaled virtual prototypes in real environments; and 2) communicate 3D projects immersively.
All you need to make AR Plug-in work is a personal computer, a webcam and a printed code attached to the software. Besides the standard visualization functions, other features include a toggle full-screen function and a real-time rendering optimization method.
AR Plug-in release works with Mac OS X 10.5 and Google SketchUp 6 or later."
