Sixth Sense

Pranav Mistry has developed absolutely amazingly awesome wearable technology, called the Sixth Sense. It's a device that can project data onto stuff you are looking at; like Amazon ratings of books you are browsing in a bookshop, or whether the toilet-roll in the supermarket is environmentally sound. Go and watch the video, it's quite mind-boggling really (and no brain implants are required - yet). More information is available at his website.

A commenter on the TED site points out that you could use it in museums to learn more about the artefacts. It could have scary applications, like seeing data about people (though it would be an interesting ice-breaker at parties). But that is the case with all new technology.

The aspect of this that beats being able to browse the web from your mobile phone is that it selects the information you need instead of you having to searchfor it; so it knows you're looking at a book or a newspaper and reacts accordingly. How? How does it know?

Anyway, in short, I want one of those.
