When a new technology or practice of media consumption shows its ability to damage the hegemony of the film industry it resorts to a series of gimmicks to try and up ticket sales. As televisions became the new standard in the American home the film business first switched to a 16:9 widescreen format, and then began going even further with its attractions by creating events around films, mixing performance art, and adding a whole number of non-film elements. It is in this climate where 3D first emerged.
Now, in a world of declining ticket sales, an unreasonable fear around film piracy, and an increasing focus on "pull" models of film watching, the 3D glasses are back. Since technologies exist in such a copacetic model in modern times it served to reason that the 3D feature made its way home to HD televisions almost immediately, and there is now a possibility that 3D filmmaking could be a staple that is going to be with us for a while.
It is with this in mind that Spatial View is developing its own iPhone app for 3D film viewing that will go along with a peripheral for your iPhone. Spatial View will not actually require you to wear glasses, as is traditionally assumed with 3D, but instead using a thin film cover that will go over your iPhone's touch screen. This will allow for a more independent form of 3D viewing, which makes a lot more sense for iPhone video watching as this is much more focused in on quick blasts of audience time rather than long sessions of film watching.
Whether or not this hand held 3D technology with your iPhone is going to be a real aspect of use will be determined entirely by where the film community goes. This technology does not have a significant history of success, but use with hand held devices like the iPhone may be unique enough to help it succeed.
