Wearable projection computer project: Internet ‘sixth sense’

A group of MIT students have developed a wearable computer that projects its display onto any nearby surface, and is controlled by hand gestures and voice-recognition. A prototype was demonstrated at TED this week, capable of projecting a watch face onto the user’s wrist after they trace a circle over it, capturing images framed by their fingers, and pulling up information about an individual and projecting it onto them during conversation.

When he encounters someone at a party, the system projects a cloud of words on the person’s body to provide more information about him — his blog URL, the name of his company, his likes and interests. “This is a more controversial [feature],” Maes said over the audience’s laughter. In another frame, Mistry picks up a boarding pass while he’s sitting in a car. He projects the current status of his flight and gate number he’s retrieved from the flight-status page of the airline onto the card

The students, led by Pranav Mistry, are part of the Fluid Interfaces group at MIT Media Lab; the prototype they demonstrated consisted of a battery-powered 3M pico-projector, a cellphone and a webcam, together with four colored Magic Marker lids worn on the fingertips. The hardware, costing less than $350, can track the lids and interpret the movements according to predefined functions, such as pulling up internet reviews of a book picked up in a store, and projecting them onto the book itself.

The technology, which has been patented, also allows mobile access to email, phone and other communication methods. A menu can be pulled up via a preset gesture, and then shortcuts – such as tracing an @ symbol to call up email – used to access different functions. More information on the project here [pdf link].
