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.'"

    5 years from now you will walk down the isle in a grocery store and every box will be animating and screaming buy me like the cereal box in Minority Report.

    I think we probably need new laws against noise pollution fast. I really don't look forward to billboards speaking to me.

    If you thought over packaging was bad now. Imagine a cereal box with 1/4 of it reserve for the battery that powers the digital paper display and 1/4 reserved for the speaker. The remaining 1/2 will be food facimille made of phosoric acid, aspertame, Hydrogenated vegetable oil, and recycled newspaper print.
