For a measly $350, you can completely revolutionize your world and the way you extract and populate streams of information from and into your surroundings. Created by students and professors at (surprise, surprise) MIT's MediaLab, Sixth Sense is the perfect marriage of digital and analog, molecules and megabytes.
That's a cute way of saying that for the first time, someone has figured out how to engineer an almost seamless connection between the real world and the internet. And the best part is, they used regular, affordable off-the-shelf electronics to do it: a camera, a mini-projector and a mobile device.
It's a bit long, but this video explains everything. Watch for yourself:
A bit more detail from Gizmodo if you couldn't get through the whole video:
"The camera recognizes objects around you instantly, with the micro-projector overlaying the information on any surface, including the object itself or your hand. Then, you can access or manipulate the information using your fingers. Need to make a call? Extend your hand on front of the projector and numbers will appear for you to click. Need to know the time? Draw a circle on your wrist and a watch will appear. Want to take a photo? Just make a square with your fingers, highlighting what you want to frame, and the system will make the photo—which you can later organize with the others using your own hands over the air...
Now take this to every aspect of your everyday life. You can be in a taxi going to the airport, and just by taking out your boarding pass, Sixth Sense will grab real time information about your flight and display it over the ticket. You won't need to do any action. Just hold it in front of your and it will work.
The key here is that Sixth Sense recognizes the objects around you, displaying information automatically and letting you access it in any way you want, in the simplest way possible."
