    The problem with any lenticular 3-D system is the limitation of the viewing area. Sure, you can lay on the couch but if you tilt or move your head a little, the 3-D will either reverse or flatten.

    Well darn it, there goes 3D porn...
    And more sarcasm...
    The loss of the glasses means we can't have "demolition sex"...(kudos to those who get the reference...)

    I think this is going to be an interesting case study in 3D. Does the general public prefer top quality 3D and is willing to put up with glasses for it, totally passive but very low quality 3D, or better no 3D than easy crappy 3D or top quality, very inconvenient 3D? Of course the studios may be rigging the outcome in the future by potentially attempting to do almost all 3D by conversion, negating the top-quality option right from the start.

    Has anyone seen the Toshiba/Philips glasses-free 3D system. It might go on sale in Dscember.

    The Dolby 3-D display certainly reminded me of lenticular, which is often used for the the glasses free 3D artwork for many 3D blurays. And just like lenticular, the Dolby 3DTV had a 50% chance of being viewed in reverse 3-D, as in Right/Left 3-D instead of Left/Right 3-D. In those cases, if you move a little to the left or right, the image is then corrected. I believe this is why the stereoscopic IA was reduced in the Dolby display. If the 3-D effect is minor at best, then it becomes harder to notice reverse 3-D situations when doing casual viewing. Once I realized this, it became a real irritant. Any time I even slightly moved, I then needed to watch the 3DTV closely to see if the "3-D light" presentation 3-D effect was then reverse or normal 3-D. The odds were 50/50.
    Watching the opening of HUGO on the Dolby autostereoscopic display, and then a few days later watching the opening of HUGO on the Panasonic AE-8000 was a night and day comparison, with the AE-8000 correctly matching the other 3-D viewings I have had this title.
    This prototype tech as currently implemented is not ready for prime time. I agree that autostereoscopic head tracking for proper and consistent left/right orientation sounds like the best way to go. It has been tried before and at the time had received good reviews at previous trade shows.

    There are demos of the Toshiba-Philips-Samsung glasses- free 3D sets on Youtube.

    Dude whats with the yelling....

    Most reviews I have read state that glasses free 3D is just not there yet. To me the limited viewing angle is going to be the item that is the hardest to overcome. Also the Dolby TV required you to sit a certain distance away from the TV. Which in our demo seemed the middle of the conference table.
