SixthSense: How It Works: A webcam captures video, including specific hand signals that the laptop reads as commands. A mini-projector then displays the relevant content — e-mail, stock charts, photos — on the nearest surface Bland Designs
Imagine a wearable device that lets you physically interact with interfaces that appear in front of you on any surface, where and when you want them. You can watch a video on your newspaper's front page, navigate through a map on your dining table, and flick through photos on any wall. The "Sixth Sense" system from Patti Maes' Fluid Interfaces Group at the MIT Media Lab does all this through a prototype built from $300 worth of off the shelf components. You can even take a photograph by simply holding your hand in the air and making a framing gesture.
