Just like the 3ds screen.
But we are getting closer to holograms so we will see what happens.
Ha, the 3ds screen is actually really REALLY old tech too. I remember seeing that kind of parralax barrier technology at a siggraph when I was a kid. Of course, thats to be expected, Nintendo never REALLY uses anything new. New technologies are unstable and untested.
Modern parralax displays have no 'sweet spots' The sweet spots are all over lapping and form a near 180 degree viewing space in 3d, while on older technology (3ds) you have to keep your head in the right place to view the effect. Of course, it is incredibly delicate and prone to miscalibration from bumps, so not something you want in a portable game system. Heres something cool, you can all watch a 3d show together, or, two seperate 2d shows at te same time (what show you see depends on where you are!) and Directional sound speakers send the audio to the correct spot (and only the correct spot!)
Holograms? Already have those too. (Also seen many MANY a time at a siggraph when I was younger) I remember Full color and everything, kept referring to them as 'star wars style', although they are highly useful visual tools, (and neat as all ****) They dont really lend themselves well to being a cinematic display, rather, just an object oriented display, like a single person, or a small group made smaller, or a large rotating can of coca cola, you cant really have backgrounds n stuff. They have come a long way from when I was a kid, now multiple people can view them from a wider viewing area, and they all see them from the angle at which they are standing (relative to each other, a person standing in front will see the object from the front, and the one at the side from the side) and you can even reach out and 'grab' them, and rotate them around!
