Touch Sensitive Paper With Built-In Speakers
The Bongo King writes "There have been several stories about digital paper discussed here on the site recently, but an offering from Swedish research scientists has a new twist. They have made a prototype billboard of interactive paper with built-in flat loudspeakers apparently also made of paper. 'Touch sensors are made using a fine pattern of conductive lines in which the current flow is altered when a hand touches it. Laptop computer touchpads use the same principle. Speakers are made by printing electromagnets out of conductive ink and stretching the paper over a cavity like a speaker cone behind the billboard. The electromagnets vibrate in response to a current, creating a sound.'"
I'm just waiting until they do the same for e-paper. Then, not only will the paper have graphics and animation, but it will have sound too. Also, I expect an embedded ccd to come in a few years, making the new media computer a piece of e-paper attached to a bulky battery.
