Sony's new creation, the ELF-SR1, is in line with the 3D dash displays we're starting to see in high-end cars. It uses a micro-optical lens over its 15.6-inch display to split an image into left-and right-eye perspectives. Then it uses a "high-speed vision sensor" to track your eye positions at millisecond frequency, so the display can generate a slightly different image for each.
The screen dynamically adapts the image in real time as you move around, allowing movements 25 degrees left and right, 20 degrees up and 40 degrees down at distances between 30-75 cm (12-30 in). And the effect is that you get a 3D image you can move around to get different views on.
It is good for filmmaking, game design, graphic design and engineering can all benefit from the ability to look at things from a dynamic and intuitive perspective. And certainly product design; anything where an end product can be previewed.
