Low-cost reading system enables visually impaired to hear graphical content

From a contact lens that delivers tactile sensations to the cornea, to a 3D-printed ring that reads text aloud in real-time, advances in technology have opened up some groundbreaking ways for the visually-impaired to consume printed content. Researchers from Australia's Curtin University have now unveiled a low-cost reading device that processes graphical information, enabling the blind to digest documents such as bills, PDFs, graphs and bank statements.

Vision-correcting display lets users ditch their reading glasses

In an age where reading something from a screen on a phone or a computer is a normal part of our daily lives, the wearing of glasses or contact lenses often makes doing so a chore with eye-strain problems and the necessity to carry around spectacles or lenses wherever you go. In this vein, researchers at the University of California at Berkeley have created a prototype vision-correcting, printed pinhole matrix that they claim fits directly to a screen and negates the need for eyeglasses or remedial lenses and may one day offer improved visual acuity to those with eye problems much worse than simple farsightedness.

Corneas regrown using human stem cells

Medical researchers working with human stem cells have discovered a way to improve regrowth of corneal tissue in the human eye. Using a molecule known as ABCB5 to act as an identifying marker for rare limbal stem cells, the researchers were able to use antibodies to detect ABCB5 on stem cells in tissue from donated human eyes and use them to regrow anatomically correct, fully functional human corneas in mice.

Nissan takes the wraps off Concept 2020 Vision Gran Turismo

“Cor, I’d like to take that for a spin.” It's what most of us think when looking at concept cars, but the chances of that ever happening are usually less than slim. The Nissan Concept 2020 Vision Gran Turismo is an exception to the rule – at least, it's a virtual exception. That’s because next month, the just revealed supercar concept becomes available for download for Polyphony Digital’s Gran Turismo 6 video game for the Playstation console. Read More

Praying mantises outfitted with tiny 3D glasses

Although us humans take 3D vision for granted, it's not a standard feature throughout the animal kingdom. In fact, praying mantises are the only invertebrates known to possess it – a fact which makes them excellent hunters. Scientists at Britain's Newcastle University are now studying the insects' ability to see in 3D, to determine if it could be copied in human technologies such as robot vision systems. As part of that study, they're equipping mantises with the smallest pairs of 3D glasses ever made. Read More

Portable scanner designed to make eye exams quicker and easier

If you're like a lot of people, you don't make an annual trip to the ophthalmologist to get your eyes checked ... and you really ought to, in order to catch any problems before it's too late. If it were possible to get them checked at a regular doctor's office or clinic, though, perhaps you might do so more often. That's one of the reasons that a team at MIT have designed a new hand-held retinal scanner, that can quickly and easily be used anywhere. Read More

Scientists run eye cells through an inkjet printer

Imagine if conditions that presently cause blindness could be treated by simply by fabricating new tissue, and using it to replace the defective part of the retina. We may not be at that point yet, but we've definitely taken a step closer, thanks to research being conducted at the University of Cambridge. Scientists there have successfully used an inkjet printer to "print" rats' retinal cells onto a substrate, paving the way for the creation of custom-made eye-repair material. Read More
