  1. 3D technology and the Human Eye By: Wells Liang

  2. Outline • 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

  3. Anatomy of the Eye

  4. Binocular Vision 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.

  5. How Humans Perceive 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.

  6. How Artificial Depth is Created • 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.

  7. 3D Polarization

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

  9. So many choices, Which to choose? • Passive Polarization Glasses • Pros • Guaranteed flicker free 3D experience. • Provides amazing visuals and very rich colors • Cons • Requires special TV that can polarize light. • Relatively new technology which contains flaws. • Active shutter glasses • Pros • 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.

  10. Interesting Things I Discovered • 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. • 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. • 3D technology dates back to 1952.

  11. Doing my Research 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.
