Okay, so an outdated article that already shows the company is failing to keep its promises. These are a dime a dozen, I'm afraid.

Another was some kind of laser based thing that had the same issues.
Oh, and a very old one, probably 2009 from MIT or something. It's a projector you wore on a long necklace that would project stuff on your arms and hands. That one actually worked decently in tech demos they showed. It could track your hands and arms so you could gesture out stuff.
Still, I have very little hope this will pull through. Not sure how the iPhone devs can help much with the main hurtle being the hardware that doesn't exist or have a working proof of concept.
Edit: I'm going to put my foot in my mouth on this one, I just say the ted talk in the adjacent comment and it seems to actually work. Smart they went with chest mounted vs bulky wrist watch.
