Very interesting
I hadn't seen the video linked in the story until now and I was very impressed. I would love to see this kind of interface come into commercial production soon. It's the way I've envisioned interacting with my computers for quite some time now. I hope Apple has actual plans for applications of this outside of the iPhone because I can see this kind of interface bringing about a huge shift in the computer industry. Especially if it can be made inexpensive and reliable.
