awesome...just a shame it'll take 60 years for it to become affordable

He might be infringing on any number of those 200 patents Apple filed for the iphone.

No he won't. He developed this before Apple did. In fact, apple's product could even be based on his work.

And this won't be all that expensive either as the key components are:
- an SVGA projector
- a camera
- an acrylic screen (or some other material)
- a handful of white LEDs (might become infra-red later)

That's it. There's a software element involved as well. It interprets the images caught by the camera. Fortunately, it's pretty simple.

i saw a few versions in person at the last NextFEST. it really cool and more complicated than some may think.

it's really quite intuative. more natural to use. I would love to "Paint" using it.

So it's not really a touch screen at all? I don't see how Apple based any of their stuff off glowing fingertips on TV, then. The iphone thing is touchy, not seeey. Anyhoo.

@weirdami

It IS a touch screen. It's just that a camera is used as part of the touch sensor. It used something called frustrated total internal reflection in order to highlight where the user has touched the acrylic screen. The camera then captures this and a computer vision algorithm interprets the images and extracts the touch locations (and "pressure" too, I think).

This is why it's going to be much cheaper than other options. It's also why this technique is scalable to huge touch screens. Jeff Han has created something that is incredibly intuitive to use and will be affordable. That's why this has a chance to actually get mainstream use.
