Novel system guides the blind by turning images into music

By - July 5, 2012 1 Picture
Sensory substitution devices work by converting one type of sensory input into another – examples would be systems such as CASBLiP and EYE 21, which allow the blind to “see” by assigning sounds to images. Now, a team of researchers at the Hebrew University of Jerusalem have created a similar wearable device, known as EyeMusic. It “employs pleasant musical scales to convey visual information,” and could one day help the visually impaired more easily perform tasks that the rest of us take for granted. Read More

GPS-enabled app helps the blind take the bus

By - June 21, 2012 3 Pictures
Like the rest of us, the blind can use speaking navigation apps to find their way around the city. A new Android application developed at Spain’s Universitat Autònoma de Barcelona, however, is designed specifically to help blind people get to their destination by bus. Appropriately named OnTheBus, the app could also be used by the deaf, the cognitively-impaired, or anyone else. Read More

Neuroscientists could help people see with their "mind's eye"

By - June 6, 2012 2 Pictures
A team of researchers at the University of Texas is exploring the possibility of electrically stimulating the visual cortex of the brain to create simple images and shapes. This development could lead to a visual prosthetic device that would effectively "trick" the brain of visually impaired or blind people into seeing ... and such a device, the authors say, is only about five years away.

“Intelligent” goggles highlight obstacles for the visually impaired

By - May 30, 2012 1 Picture
Researchers at the Universidad Carlos III in Madrid (UC3M), Spain, have developed a pair of “intelligent” goggles that make getting around a bit easier for partly-sighted people, by providing them with Terminator-style vision. Using a pair of cameras mounted on a virtual reality headset connected to a tiny computer, the device scans the area ahead of the wearer and displays information about the scene as color-coded outlines that convey the distance and shapes of objects that are difficult to otherwise see or interpret.

Navatar system could help the blind navigate indoors

By - May 24, 2012 1 Picture
When blind people are trying to navigate the city streets, they can get assistance from a speaking GPS-enabled smartphone, just like everyone else. Once they move indoors and lose access to the required satellite signals, however, it’s a different story. While there are some indoor navigation systems that require things like radio-frequency tags to be strategically placed around the building, it’s currently unrealistic to expect to find such systems installed in many places. The University of Nevada, Reno’s experimental new Navatar system, on the other hand, just requires a smartphone loaded up with a digital two-dimensional map of the building in question. Read More

New light-powered retinal prosthesis could restore sight to the blind

By - May 15, 2012 2 Pictures
Age-related macular degeneration is the leading cause of blindness in North America, while retinitis pigmentosa causes approximately 1.5 million people worldwide to lose their sight every year. Individuals afflicted with retinal degenerative diseases such as these might someday be able to see again, however, thanks to a device being developed at California’s Stanford University. Scientists there are working on a retinal prosthesis, that uses what could almost be described as miniature solar panels to turn light signals into nerve impulses. Read More

Human embryonic stem cell transplants found to improve vision in clinical trials

By - January 24, 2012 1 Picture
UCLA researchers are reporting a milestone in the therapeutic use of stem cells after two legally blind patients who received transplants of specialized retinal cells derived from human embryonic stem cells reported a modest improvement in their vision. Monitoring of the patients’ progress over a four month period also found no safety concerns, signs of rejection or abnormal cell growth. The researchers are claiming that the success of the procedure could pave the way for a new therapy to treat eye diseases. Read More

NSK develops four-legged robot "guide dog"

By - November 21, 2011 17 Pictures
Guide dogs for the visually impaired provide an important service and help provide a welcome sense of autonomy to physically-challenged individuals. Unfortunately, the highly-skilled canines require about US$30,000 in training over several months, and always seem to be in short supply. The growing demand for these specialized animal companions gave a group of engineers from Japan's NSK corporation and the University of Electro-Communications just the impetus they needed to design a mechanical solution, and the robotic guide dog was born.
