A new method to project 3D images has been worked up by a research group at MIT. This is the Media Lab Camera Culture Group who has worked out a cheaper method by stacking many LCD panels one top of the other. Each of the panel displays a slightly different perspective of the base image and each of them run at high refresh rates. This results in the human eye conjuring up the image in 3D. The technology is supposed to be able to be viewed from different angles therefore making it a glass free multi viewing capable end result.
The present glasses free technology requires either a camera on the panel which would track the eye. This system used on the Toshiba F750 3D laptop is therefore limited to one set of eye only. Such factors have limited the technology in its usage or popularity.
