The possibility of sitting down to watch some long awaited TV event and being able to holographically view the entire thing, right in the middle of your living room may sound like a big dream. However, researchers say it is a real possibility. For along time, people have been working on convincing 3D without the glasses, and so far the demo is breath-taking. 3D has been around for sometime but it requires a very large processing power as well as bulky hardware to be achieved. Lately, there has been some sort of breakthrough in the development of this holographic video system by some scientists at the University of Arizona. It is said that the researchers at the University of Arizona have created he world’s first three dimensional video displays that uses an onboard memory and can also be updated. So far the three dimensional displays produced in the labs can be erased and rewritten in only a few minutes. For a three dimensional television to be created however, the display would need to be overwritten several times in a second, something which is still very far from being achieved although researches believe it can be achieved within the next decade. This ability to erase and rewrite a three dimensional projected image is considered as a huge breakthrough in this field. Indeed it gives lots of hope that even the remaining bits can be achieved.
