Millions of smartphone users with vision problems experience a lot of inconvenience in the absence of glasses, since the information on the display is seen by them indistinctly, or completely blurred. PhD student Fu-Chun Huang at the University of California has set himself an ambitious goal: to create a display correction system that makes it possible to do without glasses.
Previous attempts have failed. The contrast of the image left much to be desired. Together with his colleagues from the Massachusetts Institute of Technology and the University of Berkeley, Fu-Chun Huang came to the conclusion that it is necessary to improve the algorithm for fine-tuning a specialized display.
On the prototype iPod, the screen was covered with a transparent film, under which was placed a thin mesh with holes. From any point in the surrounding space, only some of the pixels are visible through its micro-holes, which allows different parts of the eye to choose the optimal viewing algorithm.
This makes it possible to compensate for vision problems by adding pixels. As a result, for example, for a short-sighted smartphone user, the display will seem to be half closer. This technology is used to create a 3D effect on displays, where each eye sees a different picture.
