And, this one includes a link to the eyeMusic apple appStore page - see below - and, I'd like to hear guy's opinions as well..?
Jacob Kruger Blind Biker Skype: BlindZA "Roger Wilco wants to welcome you...to the space janitor's closet..." ----- Original Message ----- Hi All, For your information. Yesterday The Hebrew University of Jerusalem did another press release, as appended, in which The vOICe is no longer mentioned. Best wishes, Peter Meijer Seeing with Sound - The vOICe http://www.seeingwithsound.com/winvoice.htm Blind can 'hear' colors and shapes, show Hebrew U. researchers. erusalem, March 9, 2014 -- What if you could "hear" colors? Or shapes? Thesefeatures are normally perceived visually, but using sensory substitution devices (SSDs) they can now be conveyed to the brain noninvasively through other senses.
At the Center for Human Perception and Cognition, headed by Prof. Amir Amedi of
the Edmond and Lily Safra Center for Brain Sciences and the Institute forMedical Research Israel-Canada at the Hebrew University of Jerusalem Faculty of Medicine, the blind and visually impaired are being offered tools, via training with SSDs, to receive environmental visual information and interact with it in
ways otherwise unimaginable. The work of Prof. Amedi and his colleagues is patented by Yissum, the Hebrew University's Technology Transfer CompanySSDs are non-invasive sensory aids that provide visual information to the blind
via their existing senses. For example, using a visual-to-auditory SSD in aclinical or everyday setting, users wear a miniature camera connected to a small computer (or smart phone) and stereo headphones. The images are converted into "soundscapes," using a predictable algorithm, allowing the user to listen to and
then interpret the visual information coming from the camera. With the EyeMusic SSD (available free at the Apple App store at http://tinyurl.com/oe8d4p4), one hears pleasant musical notes to convey information about colors, shapes and location of objects in the world.Using this SSD equipment and a unique training program, the blind are able to
achieve various complex. visual-linked abilities. In recent articles in Restorative Neurology and Neuroscience and Scientific Reports, blind andblindfolded-sighted users of the EyeMusic were shown to correctly perceive and
interact with objects, such as recognizing different shapes and colors or reaching for a beverage (A live demonstration can be seen at http://youtu.be/r6bz1pOEJWg).In another use of EyeMusic, it was shown that other fast and accurate movements can be guided by the EyeMusic and visuo-motor learning. In studies published in
two prestigious scientific journals, Neuron and Current Biology, it wasdemonstrated that the blind can characterize sound-conveyed images into complex
object categories (such as faces, houses and outdoor scenes, plus everydayobjects) and could locate people's positions, identify facial expressions and read letters and words, (See YouTube channel http://www.youtube.com/amiramedilab
for demonstrations.) Despite these encouraging behavioral demonstrations, SSDs are currently notwidely used by the blind population. However, in a recent review published in
Neuroscience & Biobehavioral Reviews, the reasons that have prevented theiradoption have changed for the better over the past few years. For instance, new technological advances enable SSDs to be much cheaper, much smaller and lighter, and they can run using a standard Smart phone. Additionally, new computerized
training methods and environments boost training and performance. The Hebrew University research has shown that contrary to the long-heldconception of the cortex being divided into separate vision-processing areas, auditory areas, etc., new findings over the past decade demonstrate that many brain areas are characterized by their computational task, and can be activated using senses other than the one commonly used for this task, even for people who were never exposed to "original" sensory information at all (such as a person
born blind that never saw one photon of light in his life).When processing "visual' information" conveyed through SSD, it was shown by the researchers that congenitally blind people who learned to read by touch using the Braille script or through their ears with sensory substitution devices use the same areas in the visual cortex as those used by sighted readers. A recent
example of this approach was just published in Current Biology, showing thatblind subjects "see" body shapes via their ears using SSD equipment and training.
There is a whole network of regions in the human brain dedicated to processing and perceiving of body shapes, starting from the areas processing vision in the cortex, leading to the "Extrastriate Body Area," or EBA, and further connecting to multiple brain areas deciphering people's motion in space, their feelings and
intents.In tests with the blind, it was found that their EBA was functionally connected
to the whole network of body-processing found in the sighted. This lendsstrength to the researchers' new theory of the brain as a sensory-independent task machine, rather than as a pure sensory (vision, audition, touch) machine.
"The human brain is more flexible than we thought," says Prof. Amedi. "These results give a lot of hope for the successful regaining of visual functionsusing cheap non-invasive SSDs or other invasive sight restoration approaches. They suggest that in the blind, brain areas have the potential to be 'awakened'
to processing visual properties and tasks even after years or maybe evenlifelong blindness, if the proper technologies and training approaches are used."
