Glasses-free 3D screen lets you see the wider picture

Future displays may soon go even further. Researchers from the Institute of Informatics at the Federal University of Rio Grande do Sul (UFRGS) in Brazil, Purdue University in West Lafayette, Indiana, and MIT have designed a screen that can compensate for bad eyesight, too.

“It creates hologram-style imagery that adjusts itself to the subject’s eye conditions,” says Vitor Pamplona of the UFRGS, who designed the prototype and will also present his idea at SIGGRAPH.

We are experiencing a revolution in the field of displays, says Diego Gutierrez of the Graphics and Imaging Lab at the University of Saragossa in Spain. One day, he says, displays that can be tailored to an individual’s visual impairments, could be incorporated into 3D displays.

Pamplona’s prototype consists of a small, high-resolution version of a parallax barrier created using two LCD screens on top of one another. “The higher resolution allows us to rebuild the image, pixel by pixel, and project it directly onto the eye of the viewer,” says Pamplona.
