MIT NewsFlash Uses Light as Alternative to QR Codes

QR codes were supposed to revolutionize the way that we interact with the world, but that hasn’t really come to pass. Even so, a couple of guys from the MIT Media Lab have come up with a fascinating QR code alternative that they call NewsFlash. And it works in an entirely different way.

Whereas QR codes are effectively 2D barcodes that have to take up space on a page, NewsFlash is effectively invisible to the human eye. That’s because it uses flashes of pink and green light that the human eye effectively averages out and does not see; however, the camera on your smartphone can see these pulses, which are then effectively translated as binary code that your phone can then understand. Using the NewsFlash app, you are then redirected accordingly.

In the video below, as an example, a scan of a newspaper page on a tablet sends the smartphone to the same article within the app. In much the same way, a NewsFlash scan of a newspaper in a foreign language can send you an English translation of that article automatically. Of course, this will only work with lit displays and not printed materials, since regular paper can’t flash pink and green, but this could prove interesting in certain signage and other scenarios.
