Our eyes see the world differently. The way 3-D tech works in theaters has 2 images of the same part (of movie) and add differences (such as enabling lighting, change image)  to trick the brain and make it feel as if it does look 3-D. To make it stay that way, the glasses you use to view 3-D has 2 different views, there creating 2 different rotations to allow you to move your head and not have the movie

all picture 3-D Tech to look something like this:

According to http://mashable.com/2011/02/07/how-does-3d-work/#6rwIxOPyZPq9,

Our TV however, does not have a silver-coated screen (which allows light to reflect more smoothly to the viewer). Also how TV is set up to be; denying 3-D tech to be viewed at home.

We are trying to solve a way to allow that on being usable, and without gasses. As of now, that is the current problem. That is, halving the image to allow us to see on half through one eye (same for the other eye). Furthermore, the eye needs at least 50 frames. Halving the image makes each eye look 25, 25; creating a flicker.

If we do get this technology, engineering can manufacturer this technology to allow the user to connect with the digital world and see the view in a different angle.
