Films in 3D without headaches
The Disney Research Lab at the Eidgenössischen Technischen Hochschule Zürich (ETHZ) has developed a technology that is supposed to eliminate the unwanted side-effects like nausea and headaches resulting from watching films in 3D.
To generate the 3D-illusion, the he human brain needs two slightly different pictures for the left and the right eye. The greater the difference, the stronger the 3D-effect. However, the risk of getting headaches or nausea also rises. The effect thus needs to be maintained in a certain comfort zone. The algorithm developed at the ETHZ allows for the 3D effect to be corrected after the movie has already been shot.
