Vision
In another world first in the fight against degenerative eye disorders, scientists from the Universtiy of California, Irvine, have created an eight-layer early-stage retina from human embryonic stem cells. Not only is this the world's first three-dimensional complex tissue structure to be made from stem cells, but it also marks the first step toward the development of transplant-ready retinas to treat eye disorders affecting millions.

Researchers at Bionic Vision Australia (BVA) have produced a prototype version of a bionic eye implant that could be ready to start restoring rudimentary vision to blind people as soon as 2013. The system consists of a pair of glasses with a camera built in, a processor that fits in your pocket, and an ocular implant that sits against the retina at the back of the eye and electronically stimulates the retinal neurons that send visual information to the brain. The resulting visual picture is blocky and low-res at this point, but the technology is bound to improve, and even in its current form it's going to be a major life-changer for those with no vision at all. And the future potential - even for sighted people - is fascinating. Read More
It's been almost 525,600 minutes since we raised a glass to welcome the arrival of 2009 and in that time we've witnessed a daily avalanche of innovation which precipitated thousands of stories on Gizmag. Though popularity is rarely an accurate measure of quality (take Governments f'rinstance), we peered into the database to create the following list of the most read stories on Gizmag during the last 12 months, and ... the medal winners are, a gun that kills hidden people, a washing machine that doesn't use water, and cure for multiple sclerosis. May 2010 be a good one for you and yours! Read More
The versatile humanoid robot Nao caught Gizmag's attention at the 2009 International Robot Exhibition (iREX 2009). What Nao lacks in size, he makes up for in features and capabilities. Nao can see (via two cameras), will react to touch, can surf the Web and can interact with other Naos. He can speak (in English or French, so far) by reading out any file stored locally in his storage space or captured from a website RSS flow. The bot is fitted with an accelerometer and gyrometer so he won't fall down, he's also equipped with two pairs of ultra-sound senders/receivers on his torso that give feedback on several echoes so Nao is aware of obstacles close by and can avoid them.

The ease with which human beings make sense of their environment through a range of sensory signals belies the complex processing involved. Approaches to give robots the same purposeful perception we take for granted have typically involved studying visual and auditory processes independently. By combining data from both sound and vision European researchers have developed technology that could facilitate robotic understanding and responses to human behavior and even conversations, bringing us closer to a future where humanoid robots can act as guides, mix with people, or use perception to infer appropriate actions.

Scientists at the California Institute of Technology (Caltech) have created a remote-controlled robot to help test the effectiveness of visual prostheses, such as an artificial retina, which are implanted into visually-impaired patients. Cyclops the robot - or, rather, the mobile robotic platform, or rover - lets scientists “see” the results that human patients could expect without having to test the device on them first. It is hoped that this approach may spare them some unnecessary procedures and one day lead to giving blind people the freedom of independence. Read More
BrainPort for the visually impaired - ‘seeing’ with the tongue
According to the National Institutes of Health, more than one million Americans over the age of 40 are legally blind - defined by U.S. law as vision that is 20/200 or worse, or have a field of view that is less than 20 degrees in diameter. It is estimated that adult vision loss costs the country about $51.4 billion per year. A new device aims to help restore the experience of vision for the blind and visually impaired by using nerves on the tongue's surface to send light signals to the brain. Read More
One of the biggest challenges facing robotics is teaching machines to perceive surroundings and make sense of what they see. Attempting to duplicate the complexity of human perception is next to impossible, so researchers at Cognition for Technical Systems (CoTeSys) in Munich are, instead, studying how blowflies process images using a 'flight simulator'. Despite having a brain the size of a pinhead, a fly can process and interpret 100 discrete images per second – four times better than humans. Read More
The eye strain and resulting damage that often afflicts those who forget to blink while on a gaming marathon or glued to the Internet is a widespread problem. To combat this, Japan’s Masunaga Optical Manufacturing has unveiled Wink Glasses, which feature blink-sensing lenses that start to fog if the wearer neglects to keep their peepers hydrated. Read More
Cyclists aren’t always very visible to motorists, which is one of the reasons they need to be super vigilant when dealing with city traffic. As the saying goes, you need "eyes in the back of your head". To that end designer Billy May has come up with a concept design for cycling glasses that extend a rider’s peripheral vision by up to 25 percent on each side. Read More
