Toshiba unveiled the world's first glassless 3D laptop, the Qosmio F750. The F750 uses a webcam to track the user's eye position and displays slightly different images to each eye to create a 3D effect without glasses. The document then provides background information on 3D technology, explaining the different methods humans use to perceive depth like stereoscopic vision, accommodation, parallax, size familiarity, and aerial perspective. It discusses how 3D is simulated on 2D screens using techniques like anaglyph, polarized light, and active shutter glasses.

6. The F750-10Q also comes with a webcam that tracks user eye position and displays slightly different pictures to each eye to create a very peculiar 3D effect

8. What is 3D?

9. What is 3D?three-dimensional, width, height and depth (length).Our physical environment is three-dimensional and we move around in 3D every day.3D perception, also known as depth perceptionthe retina in each eye forms a two-dimensional image of our surroundings and our brain processes these two images into a 3D visual experience.

10. What is 3D(stereoscopic vision or binoculars) is not the only way to see in 3D. with one eye (monocular vision) can still perceive the world in 3D,

11. They are simply missing one of the tools to see in 3D, Stereoscopic vision:Accommodation: ParallaxSize familiarity: Aerial perspective:

12. 3D world on a flat (2D) surfaceaerial perspective and familiarity size (video camera). CGI scenes, aerial perspective so that MUST be added Distant objects appear less clearly (this is Called distance fog).

13. Display common methods include:Anaglyphic processing (red / cyan glasses):Polarized light system (polarized filter glasses):Active shutter system (LCD shutter glasses):

14. The Earliest Forms of 3D Technologymid-19th century, Charles Wheatstone In the late 19th and early 20th century1930s, stereoscope was a popular novelty in bars and arcades

15. Advantageswill make your eyes create some illusion of depth thus,imbalance and disorientation
