Touch Sensitive Paper With Built-In Speakers

Posted by Zonk on Thu Jun 07, 2007 04:01 PM
from the menu-won't-stop-singing-please-take-it-away dept.
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.'"

[+] Digital Ink On Billboards 272 comments
cdneng2 writes "The New York Times has this article on a revolutionary new billboard. It uses digital ink, versus the typical CRT, LCD, Neon, or Plasma displays that are so prominent on the newer billboards that wastes electricity. From the article: 'By creating a paste made of tiny helix-shaped particles that can be minutely manipulated with electric charges to reflect light in highly specific ways, Magink can produce surfaces that look like paper but behave like electronic screens, rendering high-resolution, full-color images without ink - or, as Magink executives like to refer to the process, with digital ink.' The billboard can display images at 70 frames per second." You can find more articles on the billboard technology on the Magink website.
[+] Hardware: Fujitsu Debuts Bendable Electronic Paper 304 comments
An anonymous reader writes "Fujitsu today announced their joint development of the world's first film substrate-based bendable color electronic paper with an image memory function. The new electronic paper features vivid color images that are unaffected even when the screen is bent, and features an image memory function that enables continuous display of the same image without the need for electricity. The thin and flexible electronic paper uses very low power to change screen images, thereby making it ideal for displaying information or advertisements in public areas as a type of new electronic media that can be handled as easily as paper. The jointly developed electronic paper will be showcased at Fujitsu Forum 2005, to be held July 14 and 15 at Tokyo International Forum."
[+] The Future of Journalism Online 53 comments
twitter writes "The slide in newspaper subscriptions continues for obvious reasons: convenience, variety, depth, cost and user control are all in favor of pull media. The BBC is wondering what this will ultimately mean for journalism. One interesting issue is brought up: 'papers like France's Libération [have] traditionally shunned advertising it deemed politically compromising and relied on its cover price for its income.' Even they see that internet distribution is the answer, but the BBC worries about the details." From the article: "The International Herald Tribune now sees itself as a media organisation rather than just a paper; their website features video stories and has taken the step of charging for premium content. 'Good journalism costs money and so we are trying to see what we can do to make sure we can continue to grow and support the business,' said Meredith Artley, director of digital development at the International Herald Tribune.

[+] News: New Entrant In the Race For Wafer-Thin Speakers 93 comments
Smivs notes another technology aiming to become the ubiquitous flat, flexible loudspeaker in public and private spaces. This one comes out of the University of Warwick, in the UK, and may reach the market before year's end. We've discussed other attempts on this problem over the years, including a touch-sensitive display that is also a speaker, and an approach based on nanotubes. "The arrangement also allows for highly directional and accurate sound, say the researchers. The speakers would be ideal in public places such as passenger terminals since the sound quality does not deteriorate as much as conventional speakers... The flat speakers are relatively inexpensive to manufacture, say the researchers, and can be printed with design or concealed inside ceilings."

    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.

      Time Magazine just ran this interesting photo essay called "what people eat." One of the interesting things to notice is how much wasteful packaging [time.com] we use compared to those [time.com] who still eat mainly for nutrition. Which is not to say I'd like to live like a refugee, only that it's a shame quality food can't be packaged without all that expense and waste [nyc.gov]: "Only about 9 percent of the cost of a box of cereal is for the cereal -- the other 91 percent of the cost is for the package and advertising." Unfortunately we humans are suckers for outwards appearance.
      • "Only about 9 percent of the cost of a box of cereal is for the cereal -- the other 91 percent of the cost is for the package and advertising."

        That's why the generic cereal that comes in big bags is so much cheaper, usually 1/4 the price, or even less. Often, it's exactly the same stuff as in the small, brightly-colored boxes with the nationally-recognized brand names.

    Sounds like a lot of current and associated structure to get this to work.

    Why not just use plastic piezoelectric benders? Then the paper will talk even when being held in free air.

    (Or hasn't the patent on that expired yet?)
    • It's probably a lot cheaper to print what they're using now. As in this whole thing will be printed on a large format inkjet, probably on several sheets of paper to accommodate the cavity.... then the cavity will be die-cut out as is standard and constructed using a cheap wood/plastic/alluminum frame. Sounds pretty cool to me.

      It's an innovative use of the new inkjet printing of circuits technique.
