Pattie Maes' from the MIT lab, demonstrates in this video, (6:47), a future ubiquitous gesture recognition interface, made possible by one of her students, Pranav Mistry. It's a wearable device with a projector that paves the way for profound interaction with our environment.
The invention is both a camera and a projector. The camera figures out what you are doing (e.g., reading a newspaper, holding a bottle of wine) and then uses the projector to display additional, contextually relevant information (e.g., providing additional real-time updates on a news story, displaying the Parker points for a bottle of wine).
Ones hands are used to interact with the projected image to drive the interface. An interesting use is when the demonstrator stands in front of another person and the device projects a tagcloud onto the person , the net computer element then projects the information from his or her blog, after the camera recognizes who it is.
