Personal cam sight
They could grab a hand, touch a cheek, even wrap someone in a bear hug, but they didn’t know what a person looked like squatting down, standing on one leg, or pumping their fists in the air.Yet despite this, these individuals were able to activate a very specific area of the visual cortex just by hearing certain sounds, correctly identifying these positions. Amedi, the brain is able to transfer the initial activation in the auditory cortex into the “correct” visual area of the brain.
Research being done at the Robotics and Mechanisms Laboratory at Virginia Tech, led by Dr.These exciting new devices can restore sight to the blind in ways never before thought possible. The small covert camera is inside the sunglasses, and the notebook PC running software is in the backpack.At bottom, a representation of the aural landscape produced by the device.It’s just like bats and dolphins use sounds and echolocation to ‘see’ using their ears.” Starting with sounds for basic shapes and lines, the participants in the recent study worked their way up to being able to identify bodily forms and positions – “seeing” them in their mind even though they had never before caught sight of a human form.Remarkably, after approximately 70 hours of training, the blind participants were able to convert the sounds into visual activity in their brains, tapping into the same areas as control subjects who had seen the target images.This included a specific part of the visual cortex – the extrastriate body area (EBA) – that is specially activated when perceiving human shapes and positions.
These participants had never before been able to perceive an entire human body.
Do you or someone you know have low vision caused by Macular Degeneration, Retinitis Pigmentosa (RP), Diabetes, or another vision condition?
Magni Sight, Inc., of Colorado Springs, Colorado, manufactures a full line of quality Video Magnifiers (CCTV's) for the visually impaired.
Neuroimaging studies have backed this up, showing that in blind people brain regions devoted to sight become rewired to process touch and sound as visual information.
Now, in the age of Google Glass, smartphones and self-driving cars, new technology offers ever more advanced ways of substituting one sensory experience for another.
Layering these sound qualities and playing several in sequence (each burst lasts about one second) thus gradually builds an image as simple as a basic shape or as complex as a landscape.
