I woke up this morning with a random thought. I'm not sure if this has already been proven, but I've reasoned that the cause of reduced eyesight accuracy from extended periods of staring at a computer screen is mostly caused by the illusion of depth that the images on the screen display. Tricking the eye to see depth on a 2 dimensional plane trains the eye over time to focus incorrectly at the depth of 2-4 feet that you're sitting away from your computer screen. In other words, 20/20 vision is a habit. Okay, so the occulus rift uses two samsung galaxy note screens for each eye, a centimeter or 2 from the eyes. Video games exploit depth illusions a lot and so this is going to fuck up people's eyes royally I think. So back to my random thought from this morning. What if we rethought the computer screen. I noticed an interesting property with mirrors a couple weeks back. Did you ever realize that mirrors have actual depth? They do. You have to look into a mirror to see the objects that it reflects. You actually have to zero in on their correct depth from the mirror to be able to focus them. In other words, a mirror does not create a 2D image, it's 3D. So here's the idea... what if each computer screen had several small LED emitters inside them. instead of one huge array of LEDs that we are now accustomed to It would have 1 emitter for say... a distance of ~1 foot, another for a distance of ~10 feet, another for ~20 feet, and so on. Each LED emitter would shoot its image onto a path of mirrors that reflect onto one another, like how a camera lens redirects the light entering it, totaling a specific distance (1 foot, 10 feet, 20 feet, etc) before reflecting onto a "master" mirror which all the mirror paths of each LED emitter project onto. The "master" mirror would replace the single LED array that we are all now looking at as we browse sciforums. So the master mirror would be a composite image of all the LED emitters. What I think this would create is a monitor that literally has depth, not the illusion of it. The tricks we now use to create the illusion of depth would become obsolete on a monitor like this... instead you would just program each objects to be displayed at whatever depth you want it to be (obviously the depth gets bit crushed to an extent... for instance if you only have 3 emitters at 1, 10, and 20 feet, you'd only be able to use those depths and objects would be "crushed" into them. The solution is to add many emitters at many depths to increase the depth resolution. This would largely fix the problem of vision impairment we now see in people who look at computer screens for extended periods of time. It would also give us a whole new realm of realism to play around with in the digital world.
