MIT Media Lab researchers have developed a new display technology that automatically corrects for vision defects and could lead to e-reader and smartphone displays that let users dispense with glasses.
Imagine being able to consult your car’s dashboard-mounted GPS display without putting your glasses on (for far-sighted drivers) or read your tablet’s display without the need for reading glasses.
The vision-correcting display projects slightly different images to different parts of the viewer’s pupil. Using technology the Camera Culture Group has already developed for their glasses-free 3-D displays, two liquid-crystal displays (LCDs) are used in parallel to carefully tailor the images displayed on the LCDs to each other to allow the system to mask perspectives. The researchers plan to incorporate a third project which diagnoses vision defects so that the same device could determine the user’s prescription and automatically correct for it.
The first spectacles were invented in the 13th century. 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.
