Blind

Dr Iain Murray and PhD student Azadeh Nazemi with the digital reading system they develope...

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.  Read More

Our age-old instinct to point at things we'd like to know more about has inspired a device that assists the visually impaired consume written text. FingerReader is a 3D-printed device that is worn as a ring on the index finger and uses a built-in camera and haptic actuators to read aloud as the user traces lines of printed words.  Read More

Researchers at the Georgia Institute of Technology have developed a glove that helps users learn to read and write Braille, all while focusing on unrelated activities. The wearable computer uses miniature vibrating motors sewn into the knuckles, and was found to assist in developing motor skills in participants without them focusing on the movement of their hands.  Read More

Researchers from the Center for Research and Advanced Studies (CINVESTAV) in Mexico have developed a pair of glasses that use a combination of ultrasound, GPS, stereoscopic vision and artificial intelligence to help the visually impaired to navigate their environment. The device, perhaps the most sophisticated of its kind, is slated to reach mass production early next year and will likely cost up to US$1,500.  Read More

Grail to the Thief is an audio game designed to be played by the blind

Games that are accessible to the blind are few and far between, and – aside from a handful of stellar exceptions like Somethin’ Else’s Papa Sangre series on iOS – those that do exist tend to be amateurish at best. But a recently-funded Kickstarter project (which still has a few days to go) aims to rectify the problem. Grail to the Thief harks back to classic adventure games like Zork, Day of the Tentacle, and Hitchiker's Guide to the Galaxy, except that instead of text-only descriptions of twisty little passages and the like, it presents the entire game through audio.  Read More

The Lechal haptic shoe, in fiery red

Three years ago, we heard about a prototype shoe that could be used to guide the wearer via haptic feedback. Designed by Anirudh Sharma, who was then a researcher at Hewlett-Packard Labs in Bangalore, India, the Lechal shoe was intended for use mainly by the blind. This week, however, Sharma and business partner Krispian Lawrence announced that the production version of the Lechal will soon be available for preorder, and it's aimed at helping all people navigate the city streets.  Read More

A prototype contact lens is designed to let the visually impaired form a picture of their ...

The Faculty of Engineering at Israel's Bar Ilan University has developed a prototype of a contact lens which could enable the visually impaired to see the world in a whole new light. Developed by Professor Zeev Zalevsky, the contact lens processes digital images and translates them into tactile sensations which can then be felt on the user's cornea, allowing them to form a picture of their physical surroundings.  Read More

Measurements from Hubble images are into translated into designs that are then 3D printed

Scientists have used 3D printing technology to transform images taken from the Hubble Space Telescope into tactile "pictures" for the blind. Astronomers Carol Christian and Antonella Nota of the Space Telescope Science Institute are experimenting with 3D models as a means of aiding education for people who cannot study visual images.  Read More

One of two versions of MIT's prototype portable scanner

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

The eSight headset in use

If someone has difficulty hearing, they can use a hearing aid to boost the level of sounds reaching their ear. If someone has limited vision to the point that they're considered legally blind, however, it's not like they can just use an electronic "seeing aid" ... right? Actually, that's just what eSight is.  Read More
