Students at the MIT Media Lab have developed a wearable computing system that turns any surface into an interactive display screen. The wearer can summon virtual gadgets and internet data at will, then dispel them like smoke when they’re done.
With some bonus creepy features that should make everyones privacy alarms go off:
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.
