New Glassess-Free Tech by MIT!

According to TG Daily, MIT’s Media Lab may have a breakthrough on their hands with auto-stereoscopic 3D technology.

They have devised a method of showing 3D images that are easily viewable by multiple people at a time, and don’t reduce image brightness.  Unlike other glasses-free parallax barrier systems that use vertical bands or fixed pinholes to differentiate the left and right views, this new system displays a dynamic pattern that is customized for the image beneath it.

This new pattern would look a lot like the source image, but have thousands of tiny slits whose orientations follow the contours of the objects in the image.  Since the slits are oriented in so many different directions, the 3D illusion is consistent – even when it is rotated 90 degrees.  While more perspectives change the pattern of the slits, it allows just as much light to pass. The article claims that resolution isn’t sacrificed, but it’s still unclear how this is done and may in fact be an error.  We will have to wait and see!
