Vision Correcting Displays for Dashboard GPS and E-Books

Larry Hardesty | MIT News Office - Technology could lead to e-readers, smartphones, and displays that let users dispense with glasses.

“Researchers at the MIT Media Laboratory and the University of California at Berkeley have developed a new display technology that automatically corrects for vision defects — no glasses (or contact lenses) required. The technique could lead to dashboard-mounted GPS displays that farsighted drivers can consult without putting their glasses on, or electronic readers that eliminate the need for reading glasses, among other applications.

“The first spectacles were invented in the 13th century,” says Gordon Wetzstein, a research scientist at the Media Lab and one of the display’s co-creators. “Today, of course, we have contact lenses and surgery, but it’s all invasive in the sense that you either have to put something in your eye, wear something on your head, or undergo surgery. We have a different solution that basically puts the glasses on the display, rather than on your head. It will not be able to help you see the rest of the world more sharply, but today, we spend a huge portion of our time interacting with the digital world.”
