IPod’s Touchless Touchscreen
What if the entire surface of your iPod was a screen, and you could wave your fingers over different parts of the screen to call up different controls? Depending on what you were doing, you could manipulate a virtual scroll-wheel or get a keyboard to pop up. What’s more, you could do this without actually touching the screen or getting it all smudged up. You could be typing in air just above the screen, and the movement of your fingers would be causing each key on the screen to enlarge as you “tap” it.
I don’t know how cool this is going to be yet, but if it works good, I think it will get a lot of attention. Not much more to say about this right now
