Hey, Had an idea that I thought I'd share. Maybe it's been thought before, although I'm not aware of it. Let me know what you think! It's inspired by the glasses-free technology of the nintendo 3DS, but scaled up to the size of a pc monitor (of any size!). As I'm sure you all know, the reason that the nintendo 3DS can be 3D without requiring glasses is that different images are received by the left and right eyes. As a consequence, this means that there is a very (very!) narrow viewing angle, and the screen has to be very small (which is why it can only used for handheld equipment). So, imagine having a 2D array of 3DS's in front of you mimicing a pc monitor (ugly, but bear with me...). Now in order to get the 3D effect correctly, they would all have to be directly facing your head. Note that it is only neccesary to pivot about the y-axis, i.e. up-down pivoting is not neccesary for this technology since our eyes are separated horizontally, not vertically. Also, all of the 3DS's would all have to be the same distance away from your head (again, left-to-right), in order to have a uniform 3D effect across the array. So in effect, you've created a tube-like monitor in front of you (or if fully extended around you, it would be like a pod). So, my idea is to construct a big screen (not a bunch of 3DS's, lol) that is bent in one direction to form a kind of semi-circle (or quarter-circle or whatever), and uses the same technology as the 3Ds to create the 3D effect. This would require the user to remain in a fixed position at the focus of the screen in order to properly benefit from the 3D effect. Further expanding on this idea, the screen could be flexible (to some relatively small degree), allowing the user to decide how far away from the screen they want to be. We all know that flexible screens are out there in development, so the technology exists to do this. The feasible range of distances would be directly related to the manufacturing process used to construct the screen (i.e. how small they can get the fabrication process without inducing too much error), which will determine pixel density. That, combined with screen size, will determine potential pixel resolution. Further expanding this idea (we're now talking ultra expensive, not for home use unless you're insanely rich), you could have a huge "screen" which goes in a full circle around you, going from floor to ceiling, creating a circular pod-like room. This room would place the user into full immersion of a computer-generated environment. While the idea of doing this with standard screens has been toyed with in the past (and possibly even done?), this idea would allow the user to be placed into a full 3D environment all around them. Wouldn't that be incredible! I bet theme parks would buy it. What do you think? Flexible 3D screen that doesn't need glasses!
