My Thesis- Passive polarization not only generates the highest video quality, but is also extremely affordable. Also, passive polarization is the most effective way to view 3-D entertainment because it simulates how the human eye naturally perceives depth.

The Eye-Anatomy of the Eye.-Binocular vision.-Perception of Depth

3D Technology-Polarization-Active Shutter

People have two eyes which allows the use of binocular vision.

Binocular vision gives a wider field of view and allows the viewer to distinguish depth.

With two eyes positioned at slightly different angles, people see two different images at once.

By piecing together the two images, a 3-D image is formed.

Polarization- Use of polarized light and a filter to generate depth.

Active Shutter- Use of synchronized shuttering technology to allow each eye to see different images.

Active Shutter glasses are synced to your TV, blocking out every other frame, allowing each eye to see a different set of images.

Active shutter glassesPros- Cheapest 3D technology in

the short term.- Uses mature LCD and

Plasma technology, most of the quirks are fixed and can be purchased for a low price.

Cons- Display may flicker and

cause headaches.- Glasses are battery

powered.

Passive Polarization GlassesPros- Guaranteed flicker free 3D

experience.- Provides amazing visuals

and very rich colorsCons- Requires special TV that

can polarize light.- Relatively new technology

which contains flaws.

1. 3D movie theaters use polarization to render their graphics. This means that if you are seated far away from the center and tilt your head at an awkward angle, you will not be able to see anything.

2. People have blinds. We don’t notice because our other eye is able to see the other eyes blind spots. You can find your blind spot by drawing two dots 3 inches apart on a note card. Cover your left eye and stare at the right dot. Move the note card back and forth and you will see the left dot disappear.

3. 3D technology dates back to 1952.

The most valuable thing I learned during my research project is the ability to compare different items like 3D technology. I initial thought that Active Shutter glasses were better because they were more expensive. I discovered the opposite. Passive polarization is better and Active Shutter was actually cheaper.

The most difficult part my research project was finding the information. Most of the technology is new, so my sources were very limited.
