Developers are developing eye-tracking software, which will bring a new "smooth" scrolling method, similar to the scrolling of the eyes. Researchers at Lancaster University in the United States say that smart watches can be controlled by the rotational movement of the eyes. Users only need to stare at the small dots on the screen to select menus to change settings, just like pressing physical buttons and clicking on the touch screen.
Hans Gellersen, the head of the university project, said: "I think this technology is more practical on smartphones, because the watch itself is designed for the eyes. Because of this, the watch was placed in the pocket at the beginning. Afterwards, you can look down with your head, there is no need to use your hands at all."
"Activate functions by tracking actions. This technology can also be used to control the TV. You only need to stare at the screen at a certain distance, and you can select specific functions through specific actions."
There can be multiple function options on the screen, each with its own rotation point, which is convenient for users to choose different options. When the user quickly selects an option, he can ensure that he does not select other options by mistake.
The eye tracking system uses a head-mounted camera to monitor the movement of the eyes, and it is already used in off-the-shelf Pupil Labs Pro equipment. Galesen said that as long as a camera with a sufficiently high definition is implanted in a smart watch, it is possible to monitor eye movements.
Eye tracking technology is being developed in many fields. For example, advertisers will use it to monitor users' browsing habits, it can be used for car prediction and tracking, and it can also be embedded in Oculus Rift virtual reality helmets in the future. Gellerson also said that the current eye-tracking technology "is already cheap", but it is not "clear enough."
In Galesen's view, the mode of operation of the circular selection system is closer to natural than the existing eye tracking system. He explained: "It takes a long time to activate a button by observation. It's not habitual to stare at the button, and it's easy to get tired after looking at it for a long time. If we display moving elements on the display, we can use eye tracking. The movement is more natural, and you won't be tired when you look at it, because it fully conforms to the natural characteristics of the eyes."
From the perspective of technological trends, wearable devices in the future are likely to be touchless devices, and even wearable devices will eventually be abandoned. It's just that the eye tracking technology is far from successful so far. For example, scrolling the screen content with your eyes is very laborious. Lancaster University's research is to solve this problem.
In the future, eye tracking technology may enter the financial payment field. If the technology matures, Bitcoin can develop faster, and developers and engineers can use the new technology to use Bitcoin in their daily lives.
The video game industry can also use eye-tracking technology. At this year's CES show, RightEye LLC launched a new PC video game that supports eye tracking technology.
Take a look at how many people around us have vision problems? Adam Gross, co-founder of RightEye LLC, said: "In the past 20 years, vision testing tools have changed a lot, and progress has been rapid. Through games, we can Better interact with patients, provide them with a fun and effective new experience, and quickly attract them to participate and respond."
Gross said that ultimately their goal is to use games to replace standard vision checks. At CES they introduced two new methods of testing vision, both using eye tracking technology.
