A little over two years ago, I wrote about Digital light… showing the way. The basic idea was that light could be modulated to provide intelligent, personalized, wayfinding. In my concept, street lighting would be used and I included an animation of how a jogger could use it. “Tall-drinks” has come up with a very similar idea — the difference is, in his concept, each person would have their own source of digital light. He’s even built a simple prototype –for jogging — using a picoprojector. Even better, he’s provided instructions on how to make one for yourself.
Fundamentally we need to understand that a projector is nothing more than a light source — a light source that can be modulated. It’s one good way of creating digital light, something that has been pointed out many times on this site.
Simply projection mapping, you say? This is so much more than projection mapping; it’s something that will make practical differences in everyone’s lives. For some examples, you might want to look at the posts listed below. Some of the applications will seem mundane and that’s exactly the point. Digital light will be part of our everyday lives.
We need to stop equating projectors with screens — “screens are prison cells for pixels“, as Natan Linder says. Once people realize that, a huge number of opportunities open up.
It’s very encouraging to see more and more people experimenting with this. I wonder when mainstream lighting manufacturers wake up to the real potential of digital light and turn it into practical products. Or, maybe it will take some unknown startup on Kickstarter to finally get the ball rolling.
Check out his video below to see Talldrink’s prototype in action. His website has more details– http://talldrinks.com/?p=329 . You can learn how to make your own on his Instructables page: http://www.instructables.com/id/Ground-Projected-Information-Display-for-night-jo/
