Display in contact lens

Enhancing contact lenses with electronics seems to be a topic that has gained research interest. Smart contact lenses for health and head-up displays article the litany of research projects underway in the field of contact lens enhancement. Sensimed has already contact lens with surface-mounted strain gauge to assess glaucoma risk. Those medical measuring lenses have lacked display.

I wrote to years ago at Augmented Reality in a Contact Lens posting that researches are developing a new generation of contact lenses built with very small circuits and LEDs.

The news today tells that the idea of those contact lenses has progresses. Electronic contact lens displays pixels on the eyes tells that the first contact lenses containing electronic displays into the eyes of rabbits as a first step on the way to proving they are safe for humans. US and Finnish team says that they have demonstrated the operation of a contact lens display powered by a remote radio frequency transmitter in free space and on a live rabbit.

The test lens was powered remotely using gigahertz-range radio-frequency energy. The power transmitter was placed ten centimetres from the rabbit’s eye and RF energy was picked up on the lens with 5-millimetre-long antenna printed on the lens. The test lens had only one pixel.

Now we have to wait displays with good resolution become available some day. Maybe some day they can replace some larger displays…

      The Bates method is an alternative therapy aimed at improving eyesight.
      Despite continued anecdotal reports of successful results, including well-publicized support by Aldous Huxley,[2] Bates’ techniques have not been shown objectively to improve eyesight,[3] and his main physiological proposition – that the eyeball changes shape to maintain focus – has consistently been contradicted by observation.[4] In 1952, optometry professor Elwin Marg wrote of Bates, “Most of his claims and almost all of his theories have been considered false by practically all visual scientists.”[

    Google’s HUD glasses have been sighted

    In December, rumors spread that Google was finishing up a prototype on high-tech glasses known as wearable head-up displays (HUD) that could tap into Google’s cloud-based location services and detail users’ surroundings. The information would then appear as an augmented reality computer display.

    According to 9to5Google, these glasses can do all that and more. The glasses will reportedly have an extremely small front-facing camera with a flash to gather information and take photos, a navigation system that is used by head-tilting to scroll and click, I/O for voice input and output, and CPU/RAM/storage hardware nearly equivalent to a generation-old Android smartphone.

    Epson’s Moverio BT-100 Android-powered display glasses available in the USA

    Epson launched its BT-100 media viewer glasses in Japan back in November, but now the Android-powered translucent visor is now available in the USA. The headset uses micro projectors to create a 960 x 540 qHD display in front of the wearer’s eyes, which appears as an 80-inch image 5 meters away, while still allowing them to see the world around them. The dual projectors mean that it’s able to display 3D content, too.

    The headset connects to a controller with a touchpad and the standard Android buttons, along with Wi-Fi connectivity that allows you to browse the web, view media, or even (as Thomas Sohmers demonstrated earlier month) control Parrot’s AR.Drone quadrocopter.

    Google reveals Project Glass: Is this your augmented reality?

    Google is providing the first public glimpse of the augmented-reality glasses being developed by its Google X research group under the name “Project Glass.”

    Why unveil them now? The New York Times and Reuters say the Project Glass team will be testing prototypes in public. The New York Times reported previously that the glasses would go on sale this year, but the Google team doesn’t mention that possibility.

    What do you think? Would you use these glasses in public, and how much would you pay for them?

    Epson’s 3D Android Glasses
    Unique eyewear lets users browse the web, watch movies, and listen to music, from anywhere

    Okay, this may not be the best looking pair of glasses on the market right now, but what they lack for in style, they make up for in jaw-dropping awesomeness.

    This is the Epson Moverio BT-100 headset and they’re the world’s first Android-based wearable display. You can browse the web with these glasses, watch movies, listen to music, and more.

    They’re not cheap — priced at $699.99

    To start things off, the BT-100 includes Wi-Fi connectivity, so users can get online if and when service is available. The whole system runs on the Android 2.2 (FroYo) platform and includes Adobe Flash player for easy web browsing and better app speeds.

    Users can toggle between 2D and 3D on a QHD (one-quarter of a fully HD-display) screen. Using pioneering micro-projection technology and advanced imaging techniques, the perceived image that the glasses display is incredibly large: it’s actually equivalent to watching an 80-inch display from a little over 16 feet away.

    The sides of the glasses are semi-transparent, so users can enjoy what they’re watching, but still see what’s going on in the real world if need-be.

    Also, 3D images can be included into the user’s surrounding environment on a “floating” see-through display.

    Apple and Facebook Should Be Terrified Of Google-Tinted Glasses

    Google’s augmented reality eyewear is coming to disrupt your face and your business model. If you don’t even have to pull your phone out to take a photo, get directions, or message with friends, why would you need to buy the latest iPhone or spend so much time on Facebook?

    It could be a year before Google eyewear reaches stores, but that’s why these and other tech companies need to strategize now. If they wait to see if the device is a hit, the world could be seeing through Google-tinted glasses by the time they adapt. Apple and Facebook’s bet might be to team up…

    Cramming all the functionality into a sleek set of glasses is going to take time and effort, but the Google(x) skunklabs is on it. There’s a dozen ways the product could flop, most obviously if the glasses are awkward and unstylish, but also if they’re too heavy, expensive, fragile, or the world is just not quite ready. Let’s forget those for a second. Say Google figures it out and the retail version of Project Glass (which may end up being called Google Eye) becomes wildly popular. How will this disrupt Apple and Facebook, and what should they do to defend themselves?

    Google Gets Transparent With Glass, Its Augmented Reality Project

    Larry Page and Sergey Brin have long had the dream of a hands-free, mobile Google, where search was a seamless process as you moved around the world. As the years progressed the vision did, too, expanding beyond search to persistent connections with the people in your lives.

    Google is revealing that it is taking concrete steps towards that vision with ProjectGlass, an augmented reality system that will give users the full range of activities performed with a smart phone — without the smart phone. Instead, you wear some sort of geeky prosthetic

    The concept video for the Glass project concentrates on the cool things you may do with it one day — create instant contact with friends, monitor feeds about weather and other info, get information about a subway station out of service, receive turn by turn directions on the way to a destination, snap a picture by command, even find your way to a certain tome in the labyrinthine Strand bookstore. Everything works perfectly because, well, it’s a concept video and not a depiction of something that’s actually perfected.

    Light-powered bionic eye invented to help restore sight

    A retinal implant – or bionic eye – which is powered by light has been invented by scientists at Stanford University in California.

    Implants currently used in patients need to be powered by a battery.

    The new device, described in the journal Nature Photonics, uses a special pair of glasses to beam near infrared light into the eye.

    Retinal implants stimulate the nerves in the back of the eye, which has helped some patients to see.

    Early results of a trial in the UK mean two men have gone from being totally blind to being able to perceive light and even some shapes.

    A pair of glasses fitted with a video camera records what is happening before a patient’s eyes and fires beams of near infrared light on to the retinal chip.

    The creates an electrical signal which is passed on to nerves.

    Natural light is 1,000 times too weak to power the implant.

    The researchers said: “Because the photovoltaic implant is thin and wireless, the surgical procedure is much simpler than in other retinal prosthetic approaches.

    Retinal Prosthesis Could Help The Blind See

    A retinal implant has given a brief glimpse of light to a small number of blind people, and could one day be a common treatment for vision loss due to injury or disease.

    Shawn Kelly, a senior systems scientist at Carnegie Mellon University, has developed a computer chip that translates camera images into electrical pulses that the nerves inside the brain can understand. The result is vision.

    The cameras are incredibly small and mounted to a pair of glasses. The digital information picked up from the camera is sent along a wire to a thin film surgically implanted in the back of the patient’s eye, between the sclera and the retina. The electrical signals stimulate the nerves in the retina, and that allows the patient to see. The system is powered via induction

    It’s a far cry from the bionic eyes of science fiction, though. The resolution is only 256 pixels total, because that’s how many electrodes can be made to fit on the back of the film.

    ordinary human vision involves approximately 1 million nerves, and more than 100 millon rod and cone cells. But it is something.

    There have been other proposals for retinal implants.

  19. Tomi Engdahl says:

    The Bio-Retina Implant Could Give Sight to the Blind, With Laser Power

    A new bionic eye implant could allow blind people to recognize faces, watch TV and even read. Nano Retina’s Bio-Retina is one of two recent attempts to help patients with age-related macular degeneration, which affects 1.5 million people in the U.S.

    Although a similar implant, Second Sight’s Argus II, has been on the market in Europe since last year, it requires a four-hour operation under full anesthesia because it includes an antenna to receive power and images from an external apparatus.

    Because of Bio-Retina’s compact size, an ophthalmologist can insert it through a small incision in the eye in 30 minutes—potentially more appropriate for seniors. The Bio-Retina will generate a 576-pixel grayscale image. And clinical trials could begin as soon as next year.


    Ordinary-looking glasses contain a battery, a power-delivering laser apparatus and working lenses


    The near-infrared laser beam, gentle enough to shine harmlessly through the eye onto the implant, provides up to three milliwatts of power to a photovoltaic cell on the eye implant.



    Six hundred needle electrodes (wrapped in biocompatible silicon and sapphire to prevent the formation of scar tissue) penetrate the retina. Each electrode represents one pixel, sending pulses of electricity to stimulate the eye’s neurons, which transmit the image to the brain.

    Google Glass and the Future of Technology

    New gadgets — I mean whole new gadget categories — don’t come along very often. The iPhone was one recent example. You could argue that the iPad was another. But if there’s anything at all as different and bold on the horizon, surely it’s Google Glass.

    This idea got a lot of people excited when Nick Bilton of The New York Times broke the story of the glasses in February. Google first demonstrated it April in a video.

    Now, Google emphasized — and so do I — that Google Glass is still at a very, very early stage. Lots of factors still haven’t been finalized, including what Glass will do, what the interface will look like, how it will work, and so on. Google doesn’t want to get the public excited about some feature that may not materialize in the final version. (At the moment, Google is planning to offer the prototypes to developers next year — for $1,500 — in anticipation of selling Glass to the public in, perhaps, 2014.)

    Google has said that eventually, Glass will have a cellular radio, so it can get online; at this point, it hooks up wirelessly with your phone for an online connection.

    The biggest triumph — and to me, the biggest surprise — is that the tiny screen is completely invisible when you’re talking or driving or reading. You just forget about it completely.

    The hardware breakthrough, in other words, is there.

    But the potential is already amazing.

    Text messages direct to your contact lens

    New technology that will allow information, such as text messages from a mobile phone, to be projected onto a contact lens worn in the human eye has been developed by Belgian researchers.

    Ghent University’s centre of microsystems technology has developed a spherical curved LCD display which can be embedded in contact lenses and handle projected images using wireless technology.

    “Now that we have established the basic technology, we can start working towards real applications, possibly available in only a few years,” said Professor Herbert De Smet.

    “This is not science fiction,” said Jelle De Smet, the chief researcher on the project, who believes commercial applications for the lenses will be available within five years.

    “This will never replace the cinema screen for films. But for specific applications it may be interesting to show images such as road directions or projecting text messages from our smart phones straight to our eye.”

    Implants to restore vision

    MIT Technology Review recently had an article by Megan Scudellari that discussed retinal implants.

    Soon, retinal implants that fit entirely inside the eye will use nanoscale electronic components to dramatically improve vision quality for the wearer, according to two research teams developing such devices.

    Retinal prostheses on the market today, such as Second Sight’s Argus II, allow patients to distinguish light from dark and make out shapes and outlines of objects, but not much more.

    This device was the first “bionic eye” to reach commercial markets. It contains an array of 60 electrodes, akin to 60 pixels, that are implanted behind the retina to stimulate the remaining healthy cells. The implant is connected to a camera, worn on the side of the head, that relays a video feed.

    A similar implant, is made by Bionic Vision Australia, that has just 24 electrodes.

    No One Is More Excited For Google Glass Than Facebook CEO Mark Zuckerberg

    On Wednesday at the University of California, San Francisco’s Mission Bay medical campus, the Facebook CEO met up with Google cofounder and special projects head Sergey Brin.

    “I can’t wait to get my own,” said Zuckerberg of Glass, while Brin tried to adjust his own pair on the Facebook CEO’s head.

    In the past, Zuckerberg has been wary of commending Google, which some see as a natural rival to Facebook in the battle for corporate Silicon Valley hegemony. Late last month during Facebook’s fourth quarter earnings call, Zuckerberg noted of his company’s connection to Google: “Even though our relationship isn’t one where the companies really talk, we are able to do a bunch of things and build some great experiences.”

    On Wednesday, “the companies” talked. And they talked about developing for Google Glass.

    While Zuckerberg excitedly tried on the device, he made sure that few photos were snapped. Despite being the CEO of a social network of more than a billion individuals who share pictures and status updates every second, he asked that the handful of observers only take private photos of him and Brin.

    From a Facebook perspective, those videos and photos on Brin’s device are likely the perfect type of content to share on their network. And with a working Facebook integration, it would presumably take the flick of a finger or the quick shift of an eye to share those memories from the spectacles to a social network, whether it be Facebook or rival Google+. Zuckerberg, though, said he had no immediate vision of an application in mind but said to Brin: “Is there anything specific you want us to be trying? If so, I want to be doing that.”

    The Facebook CEO was undeterred, constantly reminding Brin of how excited he was to get his own pair. Unlike the handful of early adopters, however, Zuckerberg will not have to submit any application or pay any fee.

    At Google Conference, Cameras Even in the Bathroom

    The future came crashing down on me this week at the Google I/O developer conference while I stood at a bathroom urinal.

    I had just wrapped up a conversation with a man who owned a pair of Google’s Internet-connected glasses, Google Glass. He had explained that one of the gadget’s greatest features is the ability to snap a photo with a wink. “It’s amazing, you just look at something, wink your eye and it just takes a picture,” he said enthusiastically.

    Everywhere I looked at the conference, people were wearing Google Glass. Hundreds of them. Maybe more than a thousand! They were on the escalator. At the coffee stations. Press lounges. Lingering in the hallways like gangs of super nerds. They looked like real people as they nibbled on M&M’s and nuts at the snack bars. Except they weren’t; these “humans” were able to take pictures with their eyes and then post them to the Internet.

    The developers present who didn’t own the company’s augmented reality glasses stared at those who did with awe.

    Often, Google Glass owners looked strange. Many were using their cellphones while wearing the glasses — defeating a declared purpose of the new gadget, to free you from having to look at your phone.

    Boffins smear circuitry onto contact lenses
    ‘Eyeballing a computer’ gets closer thanks to Anglo-Australian collaboration

    University of South Australia associate professor Drew Evans has created proof-of-concept work that could in the future lead to computerised contact lenses.

    The conducting polymer lens is an early step into what could lead to circuitry being etched into contact lenses.

    The work is combination of the University’s Future Industries Institute work into the PEDOT polymer and lenses developed by a UK contact lens firm understood to be Contamac.

    “We have been researching in this area for the last decade in the military and automotive industries, but this is the first time we have been able to bring our polymer into contact lens technology,” Evans told Vulture South.

    “It is a milestone simply because the polymer is biocompatible, meaning the body finds it friendly.

    “There have been companies over the last decade building circuitry into lenses but that is using materials like copper – you’d be taking a big risk to stick that in your eye.”

    The PEDOT polymer was first discovered in the late 1970s by three scientists who later won the Nobel Prize in 2000. Evans’ work improves on the polymer improving its properties for use in wearable devices.
