Augmented reality coming true?

The power of the online world will be much more realised when we are able to truly combine it with the real world in real time.  This is often referred to as augmented reality.  We may have to wait a decade before many people are walking around wearing visual devices (active contact lenses or eye glasses with built-in projection) to enable a more immersive augmented reality experience.  

Today I saw this video on YouTube which shows a navigation unit from BlauPunkt ... probably the most reasonable commercial product step towards real time augmented reality I have seen recently.
