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.

    Paper is now banned in schools, as the repeat playing of "The Fresh Prince of Bel-Air" caused much ruckus.

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

      Argh. Sorry, but the answer to things you don't like is not more micromanagement laws.

    once advertisers get a hold of this material, and they start showing up all over the place with irritating ads that scream at you, will either be the day I commence a campaign of BRUTAL city-wide vandalism, or I give up and move into the woods.

    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.

    ...to silence all the animated, noisy ads this invention will inevitably lead to.
