Could tablets provide a solution for anyone with vision problems? It seems unlikely but researchers are working on a display that could do just that.
The prototype tablet display that is being researched basically compensates for any vision problems the user might have. So how does it do that?
Well, the software in the tablet alters the light that is emitted by each of the screen’s pixels. This is done based on the needs of the viewer taking into account their glass prescription.
As well as this, there is also a plastic pin hole filter that it used to make the image’s sharper. The investigators working on this are from University of California, Berkeley and the Massachusetts Institute of Technology (MIT). They say that this new technology could be used by millions of people who wear prescription glasses, in order to be able to see the screens on their mobile devices more easily.
A Widespread Problem
It is estimated that about a third of people in the UK suffers from either short sightedness or myopia. In the US this percentage rises to around 40% and more than half of the Asian population suffers from some sort of vision problem.
This isn’t the first attempt to use changes to digital displays to help correct vision problems. However, the people behind this latest attempt say that it provides “significantly higher contrast and resolution”. They built their prototype model from an iPod with a printed pinhole mask on the screen. They also believe that this is the first step towards a variety of different modes such as glass 3D images.
