I was very interested in seeing glasses free 3D at CES. I was sorely disappointed at the results. If you click the link above, one of the manufacturers says it will be used for "signage." In other words, the picture is really sucky, but the effect is just good enough to where you could put a display in a mall and it would get people's attention. The screen is divided into sections using a lenticular lens. The content on the screen is multiple versions of the same subject shot at slightly different angles. Because the subject is repeated, the picture is low rez and if you're not lined up exactly with one of the angles, a blurry mess. However, when you are lined up, it looks OK, and when you walk by it or change you're point of view, the video changes with you--also impressive. Again, it will be just good enough to get peoples' attention for advertising, but nowhere near the way you would want to watch a movie. And of course the big caveat is that it's not compatible with today's HD video standard. I'm convinced that it will be many years before we see glasses free 3D in the home. The above approach could work perhaps if you could start with a 4K resolution picture before dividing up the screen. We all want 3D holographic displays that you could actually walk around someday as well, but again, these technologies are totally incompatible with what we have now.
