Samsung Patent Describes Holographic TV Technology (consumerist.com)
Patently Mobile is reporting about a new patent application filed by Samsung that lays out new holographic TV technology. Slashdot reader Rick Schumann writes via Consumerist: Holographic displays as described by Samsung would be able to make the depth the brain perceives consistent with the focus of the eyes. Lasers would be used to project holograms that float in front of the screen, which of course sounds a heck of a lot like a mini Princess Leia telling Obi-Wan Kenobi he's her only hope. The display apparatus could also include an eye tracking unit that would locate an observer's pupils and adjust how far it has to project the holographic image for optimum viewing.
Worth noting: This is just a patent application; no indication of even a working prototype.
In this context, you can be sure there is more. The patent laws of the US and other countries require that the application (and consequently, any issued patent) describe the invention in sufficient detail so that someone of ordinary skill in the art area to which the invention most nearly pertains can make and use the invention. You don't have to build one, but you do have to provide enough detail so that someone else could build one.
Laws affecting technology will always be bad until enough techies become lawyers.
means it is only for one person, or a few. This is not the holodeck you are looking for.
