watching 3D without glasses
presently everyone is behind making the virtual world more realistic...
and as we see, we have now movies coming in 3D to give that 'real' effect in the movies..
but still to get the stereoscopic experience it is always a pain to wear those glasses for hours...
so, Microsoft's Applied Sciences group have come up with a lens which makes it possible to view a 3D image without the use of the glasses.
The new lens, which is thinner at the bottom than at the top, steers
light to a viewer's eyes by switching light-emitting diodes along its
bottom edge on and off. Combined with a backlight, this makes it
possible to show different images to different viewers, or to create a
stereoscopic (3-D) effect by presenting different images to a person's
left and right eye.
