What if your dining room table could show you when your coffee or cocoa is too hot to drink? That could be a reality today: hacker Ken Kawamoto shows us how with a technique called thermal projection mapping.
Basically, it's just a combination of two things we already love: 1.) the FLIR ONE case that turns your iPhone into a thermal camera, and 2.) the projection mapping technique which can turn any surface into an animated CG masterpiece by painting it with pixels. Thermal projection mapping, then, is simply using those pixels to paint surfaces with the amount of heat they give off, as measured by a thermal camera.
The result is way cooler than the explanation, though. You can see how hot something is before you pick it up, without the need to whip out a thermometer or a FLIR-equipped phone. [Ken Kawamoto via Hack A Day]
