Wired posted a blog article about MIT guys, playing around with projected AR again. They use a pocket projector to do the augmentation right where it belongs: on the surface or object it is connected to. This has the advantage of not having to wear ugly HMDs or glasses, but of course has its drawbacks: bad image quality (too dark/fuzzy surface to project to, too bright surrounding, scewed surfaces, etc.) and privacy will be another issue: the augmentation is there for everybody! Delightful or disturbing… depends. But take a glimpse at their work to get inspired, too! Thinking about undistortion of projector images or color calibration it’s worth to take a look at the work from Oliver Bimber again.
