Bionic Eye Sends Images Directly to the Brain
A groundbreaking new technique will help to restore vision without an actual eye. Continue reading →
A new technique that uses a camera mounted on a pair of glasses could help restore vision in some blind people.
The technology, developed at Monash University in Clayton, Victoria, sends images directly to the brain and could benefit those that still have a fully functioning optic nerve as well as some functioning nerve cells called ganglion, which are responsible for transmitting visual information from the retina to the optic nerve.
At a basic level, the system involves a digital camera embedded in a pair of glasses, a computer processor and finally a chip implanted in the patient's brain.
When the camera on the glasses picks up visual information from the outside world, it sends the information to a pocket-sized processing unit worn by the user. The processor modifies the images into a signal that can be transmitted wirelessly to the chip implanted in the brain.
The chip itself is a tiny grid composed of 11 tile-like components, each with 43 electrodes that touch on different parts of the brain related to vision, including the cerebrum, visual cortex and the occipital lobe.
When the digital signal from the processor is sent to the chip and out to the different parts of the brain, it stimulates these areas, and the person - even if blind - sees flashes of light.
The idea is that the grid of 11 tiles mimics a 500-pixel field-of-vision, and over time, the brain will learn to interpret each of the signals as an object.
At the moment, the images are crude representations of the real world. "The processor is like a cartoonist," Arthur Lowery at Monash University told "New Scientist." "It has to represent a complex situation with minimal information."
But over time, the resolution would improve. Right now, researchers are focusing on ways to process the information from the camera so that it can create the clearest image on the in-brain grid.

Odds are you own a wearable computers. This past year has seen explosive growth for such devices, including fitness trackers, phone watches and motion trackers. Shipments for various devices are poised to reach 76.1 million units by the end of 2015, up 163.6 percent from 2014, according to IT research firm IDC. By 2019, worldwide shipments are expected to reach 173.4 million units. It's safe to say the industry is booming. Here’s a look at some of the most popular and intriguing wearables that hit the market this year. These wearables run the gamut in functionality, from tracking heart rate and activity to zapping your brain to improve your mood and sending off an alarm to help prevent sexual assault.
The Apple Watch
The Apple Watch, which debuted in April 2015, is a sleek wearable that resembles a mini iPhone for your wrist. It’s available in different models, including Apple Watch Sport and the Apple Watch Edition. It provides advanced health and activity tracking, including wrist-based heart rate monitoring, and can display updates or control music on your smartphone. Models start at $349.
The health-tracking Fitbit ranges in price from the $60 (for the ZIP) to the $250 (for the Surge). Known as the leader in wearable activity tracking, Fitbit sold 4.7 million devices between July and September this year, according to IDC. Real-time information about activity, exercise, food, sleep and more make this slim device attractive to those trying to improve their overall health.
This wearable zaps your brain to change your mood. The white curved Thync connects wirelessly to a smartphone via Bluetooth low-energy. After pairing it with your mobile device, Thync sends low-level pulses of electricity into your head activating pathways in your brain that make you feel calm or energized.
The second generation Motorola Moto 360 includes a heart-rate monitor, music player and GPS. Starting at $299, this Android watch can also be voice-controlled through the “OK Google” command in Google Search.
With motion-sensing technology and coaching guidance, Moov Now ($79.99), available for both Android and iOS, brings workouts to the next level. The wearable aims to improve almost all forms of exercise with instructions and real-time data, from running to cardio boxing and swimming.
Athena, developed by Philadelphia-based startup Roar for Good, is a coin-size personal safety alarm to help prevent sexual assault. The wearable, which can be worn as a necklace or used an accessory that’s clipped to a shirt pocket, belt or purse, sounds off an alarm and notifies contacts of the user’s location if it’s pressed for three seconds or longer.
A new pair of jeans called #Hellojean, created by Joe’s Jeans, are not only fashionable, but also double as a wearable device, with a dedicated pocked to charge a smartphone (as long as it’s smaller than the iPhone 6). The jeans cost $190 and the battery pack, sold separately, costs $49. The USB cord is hidden in the seams of the jeans so it can “invisibly” connect to the phone.
This wearable motorcycle helmet, with a $1,500 price tag, has a heads-up display, a 180-degree rearview camera and GPS navigation. There’s also a voice-control feature that connects to a phone and can control music.
This insole ($200) tracks your daily steps and calories burned and can also keep your feet warm. Called Digitsole, it provides an extra layer of padding to your sneakers to absorb shock and vibrations when you’re moving.
Like a Glove smart leggings fit all sizes and include sensors that take measurements -- including waist, thighs, hips and inseam -- at the press of a button.
