Ramesh Raskar is giving the second keynote at the Stereoscopic Displays and Applications Conference, Jan. 24-27, 2011, in San Francisco. His paper is entitled “Content-Adaptive Parallax Barriers and Six-Dimensional Displays: new ideas from MIT Media Lab.”
Both parallax barrier systems and the practical holographic displays are limited in that they only provide horizontal parallax. By taking advantage of this fact, his team has developed a 6D optical system that responds to changes in viewpoint as well as changes in surrounding light. His lenticular array alignment allows him to achieve such a system as a passive setup, omitting the need for electrical components.
