It’s getting to the point where almost
every movie now is being shot in 3D. They are remaking movies in 3D. Almost all
the rides at theme parks are going 3D (or 4D where your chair moves, they spray
water at you, and do aromatherapy). You can even buy a 3D TV for home (for the price
of some brand new camera bodies and maybe a lens)… but they all require those
annoying glasses! Well researchers in the MIT Media Lab’s Camera Culture group
believe they are one step closer to true glasses-tree 3D TV thanks to a new
method for producing multiple-perspective 3Dimages. In fact, this method could
prove to be more practical in the short term than holography, they claim.
There's no question that holographic TV is a long ways off
-- it's simply too expensive to sell on the market despite
"impressive" recent advancements in holographic technology. There's
also another problem: holograms currently don't move. They're pretty to look
at, but in order to make them move, they need pixels smaller than anything the
industry can currently build at large volume and at low cost. For starters, the
base technology of MIT's Media Lab system is also used in current glasses-free gadgets
including the Nintendo 3DS: layered screens with the bottom screen displaying alternating
dark and light bands. Two slightly offset images, which represent the different
perspectives of the viewer’s two eyes, are sliced up and interweaved on the top
screen. The dark bands on the bottom screen block the light coming from the
display’s backlight in such a waythat each eye sees only the image intended for
it.

My biggest fear with this new technology is my 2 year old
trying to “hand something” to Dora or creepy bug movies. Other than those I
welcome it and look forward to seeing my movies really come to life!
