Very cool! Time to tag the whole city with invisible yet camera visible tags!
“With Kameraflage, now you’ll be able to plant subliminal messages on T-shirts, movies and billboards that can only be seen with digital cameras. This context-sensitive display technology, developed by Sarah Logie and Connor Dickie, works by using colors that are invisible to us but easily picked up by the silicon chips in digital cameras. As you can see, the lovely model above is wearing a shirt that only reveals that cloud’s lightning bolt when seen through an iPhone’s digital camera, although any ordinary unmodified digital camera would get the same result. She just as easily could have placed her phone number in that cloud. Hmm. Let’s think of some other uses for this cool tech.
Another use for the technology would be to watermark video and filmed content, so when pirates try to videotape movies by taking a camcorder into the theater, there could be a big bunch of funky-looking text all over it. Enabling this is a clever trick using a patented invisible light projector developed by Logie and Dickie. More Kameraflage clothing will be demonstrated at the ACM SIGGRAPH Unravel fashion show on August 6 in San Diego.”
