A researcher at Stanford has created an alternative to the mouse that allows a person using a computer to click links, highlight text, and scroll simply by looking at the screen and tapping a key on the keyboard. By using standard eye-tracking hardware--a specialized computer screen with a high-definition camera and infrared lights--Manu Kumar, a doctoral student who works with computer-science professor Terry Winograd, has developed a novel user interface that is easy to operate.
"Eye-tracking technology was developed for disabled users," Kumar explains, "but the work that we're doing here is trying to get it to a point where it becomes more useful for able-bodied users." He says that nondisabled users tend to have a higher standard for easy-to-use interfaces, and previously, eye-tracking technology that disabled people use hasn't appealed to them.
At the heart of Kumar's technology is software called EyePoint that works with standard eye-tracking hardware. The software uses an approach that requires that a person look at a Web link, for instance, and hold a "hot key" on the keyboard (usually found on the number pad on the right) as she is looking. The area of the screen that's being looked at becomes magnified. Then, the person pinpoints her focus within the magnified region and releases the hot key, effectively clicking through to the link.
Kumar's approach could take eye-tracking user interfaces in the right direction. Instead of designing a common type of gaze-based interface that is controlled completely by the eyes--for instance, a system in which a user gazes at a given link, then blinks in order to click through--he has involved the hand, which makes the interaction more natural. "He's got the right idea to let the eye augment the hand," says Robert Jacob, professor of computer science at Tufts University, in Medford, MA.
Rudimentary eye-tracking technology dates back to the early 1900s. Using photographic film, researchers captured reflected light from subjects' eyes and used the information to study how people read and look at pictures. But today's technology involves a high-resolution camera and a series of infrared light-emitting diodes. This hardware is embedded into the bezel of expensive monitors; the one Kumar uses cost $25,000. The camera picks up the movement of the pupil and the reflection of the infrared light off the cornea, which is used as a reference point because it doesn't move.
Even the best eye tracker isn't perfect, however. "The eye is not really very stable," says Kumar. Even when a person is fixated on a point, the pupil jitters. So he wrote an algorithm that allows the computer to smooth out the eye jitters in real time. The rest of the research, says Kumar, involves studying how people look at a screen and figuring out a way to build an interface that "does not overload the visual channel." In other words, he wanted to make its use feel natural to the user.
One of the important features of the interface, says Kumar, is that it works without a person needing to control a cursor. Unlike the mouse-based system in ubiquitous use today, EyePoint provides no feedback on where a person is looking. Previous studies have shown that it is distracting to a person when she is aware of her gaze because she consciously tries to control its location. In the usability studies that Kumar conducted, he found that people's performance dropped when he implemented a blue dot that followed their eyes.

How can you say that your eyes work like an input device?
This is a philosophical question in some respects, given that some new technologies can be used for the good of mankind or to mankind's detriment. Examples include: Nuclear technology: Can power our homes; but has also killed thousands of people. Computer technology: Can perform many tasks that would take humans much longer to do; however, has also proliferated computer fraud; child pornography, etc. Cellular phone technology: Can keep us in touch virtually at all times with those who need to contact us; but has also proliferated automobile accidents and is known to cause cancer for those who live close to Cellular transmission & receiving towers.
I love the water clock. It is delicate, beautiful, and complex. It's a wonder how they invented it in 1500 B.C.E. But if you mean electronics and stuff, then I like laptops. They aren't too big or too small (small screens damage your eyes). It has a large memory and you can pretty much do anything a phone does. But it must be touchscreen. Then again, everyone has a different opinion.
1. Computer being an information technology apparatus, it cannot have any demerits, However its unlogical usage can have demerits. 2.Prolongrd sitting and operating a computer can cause strain on your eyes. 3.Computer emits radiation ( radio active energy )which passes through your body can be a unhealthy. 4.Children get addicted to computer games which affects and neglect the studies.

One advantage of blue eye technology is that it can help different forms of information systems. One disadvantage is its reliability.

If Tamer Rofaeil the invent of the blue eyes technology do it right Because it help to make some Changes and keep track with your car and no matter what type of car you have
In most depictions, Tails has blue eyes.
Cody Simpson has blue eyes.
You would say "Have your parents got blue eyes?" or "Do your parents have blue eyes?"
green eyes
His eyes are blue.
If you mean a song, than that is Mika - Blue Eyes :)
Most do not have blue eyes and the ones with blue eyes are usually blind.
