Head Tracking App Now Available On iOS – And It Works!

Head Tracking App Now Available On iOS – And It Works!

A few months back, you might remember watching the above video, which displayed some smart head tracking on the iPhone/iPad, similar to the famous Nintendo Wii head tracking video a couple of years ago. Now, that demo is available as a free demo app for the iPad 2 and iPhone 4 – and that app is called i3D.

We’ve downloaded it, and it works really well! Kinda.

Okay, let me rephrase that – for some reason it won’t track my giant enormous head. It works perfectly well with everyone else I’ve seen try it. Except me. Because of my giant oversized head.

If you happen to be in possession of an iPhone 4 or an iPad 2, I’d totally recommend giving it a bash. I’d love to see this tech integrated into an iPhone game at some point in the future.

‘i3D’ Demo App Shows Off Head-Tracking 3D on iOS Devices [Mac Rumours]


  • That looks nice 😀

    The menu can really be taken to new levels with this if Apple took it a few steps more…

    Would be a good cheap, quick and basic “3d” attempt for ipad 😀

  • I’ll put money that my giant melon of a head is bigger than yours, I literally cannot purchase hats.

    This is one of those things that evens up the whole 3D thing. If you only have one eye, the effect looks astonishingly 3D. If you have two eyes, it still works, but nowhere near as well, I don’t know why.
    Try it with an eyepatch, it is worth the experience and you get to talk like a pirate for the rest of the day.

    • Now I’m no optometrist — or smart — but I’m pretty sure that’s something to do with losing your depth perception when you cover one eye. It’s harder for your brain to tell there’s no actual depth, so it’s more convincing, or something.

      • Pretty much.
        It’s a single image, as opposed to conventional 3D which is made up of two images. So instead of each eye seeing a separate image (as with real life – Each eye sees things from a slightly different perspective), you’re getting the same perspective with both eyes. That makes your brain go “Gyyahh!?”
        Covering up one eye negates the gyah (Science lingo).

        • And for the same reason (except in reverse) that’s why all the other 3D tech is useless to people whose brain *doesn’t* interpret the two images into a 3D image. You’d be surprised at just how many people can’t see 3D.

  • Works heaps better on the iPad2 than on the iPhone4. It doesn’t track me on the iPhone but iPad rox.

    • tell me about it.. my huge noggin (64) means if I want a decent hat I have to special order (think wait three months…)

      and yeh.. didn’t work that well on the iPhone 4

  • yeah while it looks awesome in the video i had a tough time getting it to show the correct perspective on my iphone4.
    probably didnt help that when it was capturing my head it seemed to include my neck (and some of my chest).
