The next thing you'll notice is the top screen's 3D effect, which pops into view much more easily when viewed at an angle. This is a benefit of the device's new eye-tracking capability that tailors the 3DS' parallax technology specifically to where you're looking from, enabling the effect to work from a far wider range of vision.
The result works a treat, and allowed me to lean over and watch my Monster Hunter partners on their own screens from over their shoulder in 3D. Even attempting to trick my 3DS by turning it rapidly didn't seem to wreck the effect. And I tested it while wearing glasses. It is genuinely impressive stuff.
I am somewhat surprised, I figured they would faze it out but it makes me wonder if the next Nintendo handheld will also have 3D?
