Mobile AR without markers

Hi all,
I’m aware of the current “hot” AR technologies like Spring and Qualcomm, but I just discovered this app/game:
http://itunes.apple.com/be/app/skinvaders/id447950387?mt=8
Which uses face-tracking for a game.
I was wondering if this is the way/start of AR without the need of markers (single or multiple).
Is anybody aware of plugins/software which can be used in Unity that offer this face-tracking or some kind of other markerless tracking which is already done by video-tracking software (more kind of camera-tracking)?

Probably the biggest problem is to do camera-tracking in real-time on a mobile device with limited power. That’s why marker-tracking is “easier/popular” since it requires less computational power.

Google for “openvc + iphone”

Hi Marjan,
I saw that earlier, but it seems difficult to get it working when you don’t have good technical/Xcode/C+ skills :frowning:
Also to get it to work in Unity seems a bit beyond my skills.
For anyone interested, the best link I could find is:
