New Posters to Feature 3-D Advertising
Remember the little cards that came in cereal boxes? The ones that made images change and seem to pop out of the card when swiveled back and forth? Well those are about to get much larger, and could be used to display 3-D advertising on the street.
Displaying 3-D billboards won't require passers-by to wear special 3-D glasses though. The Fraunhofer Society, a German research organization, has shown how to use lenticular lenses, similar to those found in the old cereal box surprises, to display 3-D advertising on a large scale.
Fraunhofer has developed technology to embed 250,000 lenses in a grooved sheet, each lens about 2mm in diameter. The improved manufacturing process improves image accuracy, according to Fraunhofer, making the 3-D image clear even at a distance.
"The advertisement glows in three dimensions. If the observer gets closer to it, the image appearance changes with each step and adjusts to the visual angle. The visual impression when sauntering past a 3-D depiction of columns is as if you were walking past a row of them for real," the company said in a statement.
