Could be refined, though I see it being practical at some point. Would be neat for remote access or even home application. Imagine your doorbell rings and you take out your iPhone and you see who is there.

"Reverse Pinch" = Stretch?

Would be even cooler if you could pan with the accelerometers! Awesome concept non-the-less.

Alex, that is hands-down the coolest iPhone app I have seen!

After initially thinking that the Accelerometers would have made for cool pan/tilt, I came to the conclusion before reading these comments that it wouldn't work that well. I think there are 2 problems: 1) The transport delay. Even on a WiFi connection there is an annoying delay between "stimulus" and "response". Studies in the '60s showed that most people can never get used to even a 500ms. delay in a control system that depends on visual feedback. And if you were on an EDGE connection, forget it! 2) The accelerometer "scaling" would have to be too touchy, to avoid having to contort your body to still see the screen while tilting it like a crazy marble game. Add the visual-feedback-destroying transport delay, and ewww!

The "swipe" pan/tilt works a little better, because it is easier to "take another swipe", than it is to keep tilting. I guess the real problem is the massive "pan" range (even up to 360 deg. on some cameras).

I say, you're going to end up either keeping the swipe gestures, or coming up with some sort of "The farther off "flat", the faster you KEEP scrolling toward the "lower" side(s) of the iPhone/iPod Touch. But, those systems have to have a prodigious "deadband" (think of a virtual circular bubble-level), so that you aren't clogging the comm channel with endless streams of PTZ commands, like MIDI real-time controllers tend to do with that interface.

I have some additional capabilities for this excellent beginning that I'd love to discuss with you off-list, if you are interested.
