have been (trying) to catch our eyes for some time now, but a team of Swedes are apparently hoping that adding speech
abilities might convince you to take an even closer look. The Paper Four project has reportedly developed a prototype digital paper that uses embedded sensors
to detect touch, and when you graze over a certain spot, it actually talks back to you via "printed speakers." Now in the fourth generation of development, the device combines paper with "printed graphic codes and electronically conductive ink that is sensitive to pressure," and it is already being showcased as a way to invite tourists or other customers to get up close and personal with ads in order to hear auditory information. Best of all, the team has hosted up a video showing exactly how this stuff works, so do yourself a favor and hit the read link to catch a peek.
