i3D — Head Tracking for iPad: Glasses-Free 3D Display

Head-Coupled Perspective on Mobile Devices. We track the head of the user with the front facing camera in order to create a glasses-free monocular 3D display. Such spatially-aware mobile display enables to improve the possibilities of interaction.
It does not use the accelerometers and relies only on the front camera.
The demo with the targets has been inspired by the work of Johnny Lee ( http://youtu.be/Jd3-eiid-Uw ) with a Wii remote.

If you want to try this demo, just download i3D on the App Store! But remember this is still work on progress...

Your idea has just been patented by Apple. Congratulations.

@twilight1138 Thanks :) Yeah I know... But there have been a lot of previous works on Head-Coupled Perspective since the 90s. I don't know if the patent is legit...

Thank you to those who miles the song. I am really glad it was picked to as the trailer's soundtrack. Those who asked: the song can be downloaded from Jamendo.com. Just enter my artist name "Daduk" to find it.

@daduk2006 Thanks for this wonderful song! Sorry, I didn't ask for your permission before using your song :(

there is a Nintendo DS game using the same method

[DocteurCube]

@rexmax Yeah, it's called "Hidden 3D Image: There it is!" (Nintendo DSi Ware, 2010)

[DocteurCube]

@BEgamedesigner The 3DS sends two slightly different pictures to your eyes: one is for the left eye and the other one is for the right eye. This is called stereoscopic 3D.

With i3D, your eyes receive the same picture and you have to slightly move the iPad and/or your head to see the 3D effect. This is called Head-Coupled Perspective (HCP).

It would be great to combine stereoscopic 3D and the HCP 3D.

Steve jobs would have loved you...

I hope you are able to get some money from Apple when they get their patent :)

[jlmei3]

So what happens if you want to lend the ipad to someone else for a minute? Does it track to their eyes instead? What if there are two people? You showed limited tiltings, what happens when you tilt more?

apple did nothing but steal the pattent by copywritting something they didnt invent, once again.

Camera / photo recognition apps = laggy trash.
