    Head tracking looks better on video than in real life.


    The following video shows a free iphone/ipad 2 app called i3d


    if you download the app you will see it is not nearly as good 3d as video.
    If you close one eye or video the app then you get the full effect

    what is creating the 3d illusion ?

    I have been looking into "monucular latency" as an explanation
    the video cam use a single lens and records at a different frame rate than the app and somehow gets translated by brain as increased depth?

    This is eye or head tracking, the camera tracks the position of the head/eyes of the viewer and updates the view accordingly. It can only work for 1 point of view at a time, search for 'johnny Lee headtracking' on YouTube for an explanation of the concept.

    I'd love to see this combined with stereoscopy and used in gaming, could also maybe be used to view 360 VR sources on a TV or other flat screen.

    Wow this is awesome, wondering if this can be applied to something else?

    @alexi_drago - I agree. This must be eye tracking. Tablets and pretty much anything with a touch screen can be enabled for eye tracking technology.
