Technology changes every day, and the innovation sees no boundaries today. When 3D movie options came into picture, it became extremely popular. All you had to do is wear 3D glasses and go for it. Now the world is stepping towards another innovative option, wherein no 3D glasses will be required. Cinema 3D, a name given to the new technology allows 3D viewing without any glasses. It has successfully overcome the barriers to 3D viewing that were earlier present. On a large scale also, like in a theatre it has proved to be successful. However, it is not made commercial viable yet.
Researchers are still working on it, to make it a more reachable option for businesses. The 3D glasses are becoming a cumbersome affair for the present generation; hence a change is surely needed. A few 3D glasses strategies already exist, but nothing has come out to be as commercially successful. When you have to serve a huge population, things need to be planned out accordingly. It is easier to make a home TV with 3D screen, but for a theatre screen it needs more efficiency. The 3D screen technologies cannot be rendered to big screens till now, due to the ineffectiveness of avoiding parallax errors.
In case of a home use TV sets, for avoiding the parallax barrier the TV set needs to be placed at a specific distance from the viewer. Hence, the technology is not viable for cinema halls. Not only the distance, but the angle from which people are watching the screen also matters. By careful design of optical elements it can be achieved, but there is no success in this field as of now. The farfetched future might bring on some authentic way out for the problem. Till then, viewers have 3D glasses as the only expected option to hang on.
