As researchers look for better ways to diagnose Alzheimer’s disease in its early stages, one promising detection methodology to emerge is a simple eye tracking procedure developed by scientists at Lancaster University in conjunction with Royal Preston Hospital. The results of such tests can help flag initial signs of memory impairment that are associated with the onset of the disease.
While IFA 2012
may be thought of primarily as a venue for electronics manufacturers to unveil their latest products, it’s also a chance for them to showcase technologies that they’re still developing
. An example of the latter is the prototype eye-controlled TV, created by Chinese electronics firm Haier. We had a chance to try it for ourselves, on the trade show floor in Berlin.
Retaining the ability to communicate effectively can be one of the key challenges facing those who suffer a severe restriction in mobility. Conditions such as Amyotrophic lateral sclerosis (ALS) can reduce a persons capacity for voluntary movement to the eyes only, though even this is not always possible. When eye movement is
possible however, it offers an opportunity for communication and expression, as previously highlighted by the Eyewriter project
. New research conducted at the Université Pierre et Marie Curie-Paris may offer a further breakthrough in this area by enabling writing in cursive using only eye movements.
If the movie 2001: A Space Odyssey
taught us anything, it’s that computers know when we’re telling a lie. While that may not actually be the case for most computers in real life, it could
be if they’re running a program created by scientists from the University at Buffalo. Building on a previous psychological study, the team produced software that allowed a computer to assess a speaker’s eye movements, to determine whether or not they were telling the truth in a prerecorded conversation. It turns out that the computer was able to correctly able to spot their lies with 82.5% accuracy. According to the researchers, a trained human interrogator only manages a success rate of about 65%.
Eye control innovator Tobii introduced and demonstrated its latest eye control technology at last week's Consumer Electronics Show in Las Vegas. The Gaze interface for Windows 8 is said to take advantage of the operating system's large tile layout to offer users a superior interaction experience, that neither touch nor mouse alone can provide.
Could you one day control your smartphone by just looking at it? Tech company Senseye thinks so, and is developing the technology to do just that. The technology uses the forward-facing camera on your smartphone to locate your eyes and then estimate where you're looking on the screen. The computer-vision algorithms used are precise enough that your phone will be able to tell even what icon you're looking at, allowing you to open programs, or even control games.
When I was a good bit younger, I wasted far too much of my spare time blowing up wave after wave of space rocks - and the occasional flying saucer - trying to get to the flip-over. Atari's most successful game, Asteroids
, has now been given a futuristic make-over by eye-tracking and eye control specialist Tobii, developers of the impressive laptop prototype
and the stand-alone PCEye
system for Windows PCs. Built as a free-standing arcade game, EyeAsteroids
players use only their eyes to aim and fire a laser at flying rocks and save the world from impending pulverization.
This unique and worthwhile project was put together by a 17-year-old electronics and programming whiz from Honduras, of all places. The Eyeboard system is a low-tech eyeball-tracking device that allows users with motor disabilities to enter text into a computer using eye gestures instead of a physical interface. This kind of system is not unique - there's plenty of eye tracking interfaces
out there - but Luis Cruz has figured out a way to build the full system into a set of glasses for less than US$300, putting easier communication within reach of users in developing countries. He's also releasing the software as open source to speed up development. Personally, I spent my year as a 17-year-old in a series of heroic failures trying to impress girls with my air guitar.
Glasses-free 3D displays are getting larger with the 20-inch LG Cinema 3D DX2000 computer display being the latest addition to the glasses-free 3D line of devices. The newest LG Cinema 3D display utilizes similar webcam-based eye-tracking technology as the latest glasses-free 3D gaming laptop Toshiba Qosmio F750, aimed at dealing with the common "sweet spot" 3D technology issue.
Sweden's eye tracking and control innovator Tobii has announced the release of a stand-alone eye control device called PCEye. Like the laptop-based prototype
system demonstrated at CeBIT last month, the device tracks eye movement and translates it into mouse cursor action onscreen. Positioned in front of a PC monitor and connected via USB, the company says that the technology is compatible with a wide range of software and has been primarily designed to improve computer interactivity for users with impaired motor skills, such as stroke victims.
