This is a selection of my favorite videos of Augmented Reality. Augmented Reality is being commercially developed on all sorts of platforms these days, including smart phones (like Enkin on the G1) and game consoles (like Eye of Judgement on the Playstation 3). Clearly a promising new combination of technologies.
ARToolkit Demo
ARToolKit is an open source set of libraries for managing various components of AR applications. This video shows off some of its capabilities.
Gizmondo Augmented Reality Game: Catapault
The Gizmondo was an open source gaming platform which led to cool homebrewed games like this one:
Total Immersion at Demo 2007
Total Immersion does AR Magic for events. It's more sophisticated than most of the demos I've seen, but requires much higher fidelity components: HD Cameras, More computing power, etc...
Eye Of Wonder For Playstation 3
Eye of Wonder is a lot like the Catapault demo above: but this made it into production. It's based on Sony's CyberCode technology, which is a marker based AR technology that they have been developing for many years.
