How the Eye Works
-Lights reflects off of an object, enters the cornea
-Light is bent in the cornea and the rays are sent through the pupil
-The iris (colored part) opens and closes pupil
-Lights rays pass through the lens and focus them on the retina
THe retina (covered in sensors) sends images to the optic nerve
-Optic nerve sends images produced to the brain

5. How it works -Visual image displays5
How it works
-Visual image displays
-Projection onto any surface perceived by the eye
-Lazers
-Diffraction
-Light intensity recording (holograms)
-Retinal direct
-Synaptic interface
-Brain computer interface

6. 6
Holograms
-Diffraction pattern, a very fine pattern of lines and pixels
-Tricks your eyes
-Appear screenless
-Limited in size
-Work on the same wavelength as visible light
-3-D
- Magic Eye books, creepy clown pictures

Holograms
-Hologram videos are the same as a picture with exception to the number of pixels required (they change over 60 times a second!)
-Lazers

8. Retinal Display -Images are projected directly onto the retina8
Retinal Display
-Images are projected directly onto the retina
-Different from visual image because you aren't seeing light reflected from an object
-Once technology is develeoped for public use, the application will offer extreme privacy for user. (light is sent only into user's pupil)
-Goggles, contacts
-No limit to physical screen size
- Military already uses them

9. Synaptic Interface -No light use at all9
Synaptic Interface
-No light use at all
-Information bypasses the eye and is transmitted directly to the brain
-Nothing has been implemented in humans
-Tests on animal subjects and their optic nerves have shown success

10. Brain Computer Interface10
Brain Computer Interface
-"Mind Machine"
-Direct communication pathway between the brain and the external device
-Technology will someday allow people who are visually impaired to see, just like a person who is hearing impaired can hear with the use of cochlear implants
-Computer reads signals from brain and can control robotic limbs
-Linking of 2 brains
Brain Interface

That's a Wrap
-This incredible technology is used today
-Researchers are currently working on ways to project 3-D images onto any surface (or without a surface) and allow users to interact.
-Researchers are developing displays that project images directly into a user's retina.
-Reseachers are developing ways for users to see images without the use of eyes.
-A kind of "Non fiction-Science Fiction"
