There is some expo in Tokyo. Well, hitachi presented 3d holographik display they say they were impressed by one from star wars and decided to make one. It looks very very very very cool. When i saw it on tv, display showed jap girl and then if im not wrong it was Yuna from Final Fantasy X2, dressed as white mage. Full 3d, able to look from every side.

I saw it on CNN last night, well the end of the story about it anyway.
looked pretty good but its done with fast rotating mirrors so I gathered

Sorry mate im on wap. But it looks really cool. Somehow on tv it looked blinking. And they say it wont be released soon cause they havent solved all the probs. The holo was sized like a 15 cm in each dimension but were low contrasted. Anyways it looks COOL!

if that holo thing is implemented on mobile phones, it'd be great.it'll be like having multitasking on a mobile, on the move too. |

Hitachi develops omnidirectional 3D display
By Yoshiko Hara

TOKYO — Hitachi Ltd. has developed a prototype three-dimensional display that can show an object from any and all directions, a full 360 degrees.
The Transport 3-D display system, built by the Hitachi Human Interaction Laboratory, is essentially a cylinder with a projector at the bottom and a mirror at the top, facing it. In between, 24 mirrors are arranged along the cylinder's circumference and a rotating screen sits at its center.
After a proprietary camera captures moving or still images of an object from 24 directions, the projector projects them to the opposing top mirror. Images are then reflected at a certain angle to each of the 24 mirrors set along the cylinder's circumference. Those mirrors in turn reflect their views of the image onto the screen, which rotates 30 times a second.
The screen shows each of the 24 reflected images one by one as it turns to squarely face the associated mirrors. Since the rotating screen is double-sided, viewers see images at 1/60 second from a particular angle, Hitachi said. The result, to the viewer's eye, is a 3-D image.
Hitachi researchers designed the center screen with a limited viewing angle so that adjacent images would not overlap. The screen, the omnidirectional camera and software to control the system are key technologies, but the system is relatively simple and based on existing technologies, the company said.
The company is doing a feasibility study on the business prospects of the 3-D display system. It cited possible applications in advertising and arcade games. The Transport system's simplicity, and its ability to display both moving and still images in full color, make it an attractive alternative to holography, Hitachi said.
Holography has been seen as the most likely way to deliver three-dimensional images, but it still has to clear a big technological hurdle if it is to display real-time moving pictures.

For those with CNN's superpass for watching their broadcasts on Real Video, there's a video on http://www.cnn.com/TECH/ on this as well - I haven't seen the video because I don't have this superpass account  | |
