New Japanese tech which can project both 2D and 3D content simultaneously, which also has other potential uses - video embedded below:
2x3D, developed by the Shirai Lab at Kanagawa Institute of Technology, is a system that lets the same screen be viewed simultaneously by people who want to watch it in 2D and 3D.
Whereas conventional passive 3D systems use polarizing filters for both the left and right eyes, this system uses a special picture-generating algorithm. Pictures for the left eye can be seen with the naked eye and only pictures for the right eye need to be viewed through a polarizing filter.
"Previously, you’d have seen double image, like this. In our system, seeing a double image when you take the glasses off has been eliminated by computing with a real-time GPU."
"This system has several applications. One that’s easy to understand is multilingual viewing. For example, I’m giving this presentation in Japanese, but the pictures themselves could be in English. What’s important is that everyone looks at the same screen, and the information delivered is different for people who are wearing the glasses and people who aren’t."
