iPhone 4′s retina display claim put under the math microscope

digg_url = ‘http://digg.com/apple/iPhone_4_retina_display_claim_put_under_the_math_microscope’; Samsung might have entertained us with some trash talk about the iPhone 4′s IPS LCD yesterday, but this stuff is of a rather more somber variety. Raymond Soneira, president of monitor diagnostics firm DisplayMate, has said that Apple’s retina display marketing is inaccurate, because he believes a display that truly makes pixels indistinguishable to the human eye would require a density in the vicinity of 477dpi. The iPhone 4 has 326dpi, and by now you might be surmising that Steve Jobs flat out lied when he said that the iPhone 4′s pixels are too small for the human retina to discern from 12 inches away.
But not so fast, says Phil Plait from Discover, whose résumé includes calibrating a camera on board the Hubble space telescope. He’s done the math too and finds that the 477 number applies only to people with perfect vision. For the vast majority of us, Steve’s claim stands up to scrutiny; even folks with 20/20 eyesight wouldn’t be able to tell where one pixel ends and another begins. So it turns out Apple can do its math, even if its marketing isn’t true for every single humanoid on the planet.

EyeSight Allows You To Control Your Phone Via Hand Gestures



While voice activation is a pretty useful feature, many folks have had frustrating experiences when the technology isn’t implemented well. So what alternatives are there? Well, EyeSight’s Natural User Interface might be a possible solution, as it uses the cell phone’s front camera to detect hand motions, allowing developers to write applications to support these gestures. An example would see users playing music, changing tracks, browsing photos or even fiddling with your GPS navigation software all just by waving your hand in front of the cell phone as if you’re performing a magic trick. Seems like a pretty useful bit of tech, and you can check out a video demonstration of it after the jump.

EyeSight’s hand-waving, gesture-based UI now available for Android (video)


Sure, the Evo‘s front-facing camera enables you to call your snookums and let them see your mug while you two exchange sweet nothings. But, wouldn’t it be much better if you could tell your phone to talk to the hand? Now it can… at least in theory, with the availability eyeSight libraries for Android. EyeSight’s Natural User Interface relies on a phone’s camera to detect hand motions, enabling developers to write apps that change tracks, ignore callers, and display text messages with a wave. The down-side is that those apps need to be specifically written to work in this way, and while the libraries have been available for Nokia handsets since last year, right now we’re seeing a whopping four programs that use it (including the hugely important “Fart Control,” which turns your phone into a “motion detecting fart machine”). So, you should probably not expect a revolution here either. Video demo from the Nokia days is embedded just below.

Ford Eco-Route plots most fuel efficient path, tells you how much longer it’ll take



Ford’s been slowly but surely tweaking its MyFord Touch interface for months now, and the latest stroke of genius to come across will surely light up the faces of treehuggers. In an effort to provide more routing options to drivers, the automaker is showcasing its new Eco-Route function in the 2011 Edge, which may or may not cause velitation with the good folks over at Garmin’s similarly titled ecoRoute project. At any rate, the new addition allows motorists to choose between the fastest route, shortest (distance) route or most fuel efficient route, and it places the estimated time of travel for each within eyesight. We’re guessing that most of you would simply select the method that requires the smallest investment of time, but those with nothing but may enjoy the new option. And somehow, somewhere, Mother Earth is blowing you a carbon-free kiss. Check out a brief demonstration video after the break.

NC State’s refreshable Braille display could revolutionize reading for the blind

While many in Raleigh are wondering whatever happened to the glory days of 1983, Dr. Neil Di Spigna and company are doing far more productive things at NC State. It’s no secret that the holy grail of Braille is a tactile display that could change on a whim in order to give blind viewers a way to experience richer content (and lots more of it) when reading, but not until today have we been reasonably confident that such a goal was attainable. Gurus at the university have just concocted a “hydraulic and latching mechanism” concept, vital to the creation of the full-page, refreshable Braille display system. As you may expect, the wonder of this solution is the display’s ability to erect dots at the precise points, retract them, and re-erect another set when the reader scrolls through a document or presses a “link” on a website. We’re told that the researchers have already presented their findings, and if all goes well, they’ll have a fully functioning prototype “within a year.” Here’s hoping a suitable replacement to Lee Fowler is also unearthed during the same window.

LookTel, an app for the blind


Now here’s a ray of sunshine on a cloudy day. LookTel is an object identifier – you point it at something and it tells you what it is. You can teach it to recognize new objects and by aiming it at a product, the program can tell what it is using real speech and when you need to ID something on the fly, you can stick on an image sticker and read that sticker. It’s more or less a barcode and QR scanner with some image recognition thrown in, but it really could be a boon to those with failing – or failed – eyesight.

ETS 50+ targets the elderly



For those who are thinking of getting a cellphone for their aged parents, how about the ETS 50+ from Shanzai? This model was specially designed to cater to folks who are suffering from failing eyesight as well as poor dexterity, since this model comes with large buttons, huge fonts, rockers on the side that makes it a snap to access both radio and volume controls, alongside an emergency switch located on the back that allows you to make a call to a pre-defined number when activated.

Stem cell therapy restores British man’s eyesight

Russell Turnbull, now 38, lost almost all the sight in his right eye after trying to break up a fight and being sprayed with ammonia 15 years ago. The result for him was what’s known as Limbal Stem Cell Deficiency, which caused him great pain, the need for therapeutic treatment, and economic dependency. Good news for Russell is that he can put all that behind him now, after becoming one of the first recipients of a new stem cell grafting procedure, whereby healthy tissue from his left eye was implanted into his right and — just like a video game medpack — restored his vision to normal. For the moment, this treatment is limited to patients with at least one healthy eye, but given the pluripotent nature of stem cells, it is hoped that tissue from elsewhere in the body could one day be used to regenerate damaged parts, such as the cornea in this case. You may find further enlightenment in the video after the break.

British surgeons using radiation beams to halt macular degeneration


We’ve seen more eyesight restoration efforts than we could easily count, but rather than tooting their horn about some theoretical discovery, boffins at Kings College Hospital in London are actually putting their hard work to use on real, live human brings. The new process, which goes by the name brachytherapy, is a one-off treatment for macular degeneration. In essence, surgeons carefully light up a beam of radiation within the eye for just over three minutes, which kills harmful cells without damaging anything else. A trial is currently underway in order to restore eyesight in some 363 patients, and everything thus far leads us to believe that the process is both safe and effective. As for costs? The procedure currently runs £6,000 ($9,889), but that’s still not awful when you consider that existing treatments involving injections run £800 per month. Hop past the break for a video report.

Video: doctors implant tooth into eye, restore sight, creep everyone out

digg_url = ‘http://digg.com/health/Video_doctors_implant_tooth_into_eye_restore_sight_creep’; Osteo-odonto-keratoprosthesis. It’s a real procedure that really does revive people’s ability to see, yet we get the feeling that people will be more, um, excited about how it’s done than why it’s done. The seemingly Mary Shelley-inspired doctors extract a tooth from a blind person and drill a hole through it, where a prosthetic lens is placed, and the resulting macabre construction is implanted into the blind person’s eye. The tooth is necessary as the body would reject an artificial base. It’s not at all pretty, and it cannot repair every type of blindness, but it’s still a major step forward. To hear from Sharron Thornton, the first American to have undergone the procedure, check the video after the break, but only if you can handle mildly graphic content — you’ve been warned.
