不久的將來，人們手中的智能手機和平板電腦就或許可以用眼睛來操控了。一直致力于研究幫助殘障人士用眼睛控制電腦技術的公司GazeGroup打算將該技術應用于適合普通用戶使用的領域，這樣不但能惠及更多人，同時還能明顯降低此類技術的使用費用。據悉，該技術通過電腦設備向用戶臉部投放紅外光線，在校準用戶的眼睛活動方式之后，該技術便可輕松感知用戶眼睛活動的方向，并由此控制電腦光標。該公司負責人表示，雖然目前大部分智能手機和移動設備都未配備紅外裝置，不過他們可以通過安裝屏幕過濾器來使用該技術。

In the near future, we may be using our eyes to operate our smartphones and tablets, even when it comes to playing popular games like Fruit Ninja.

NPR profiled the GazeGroup, which has been developing eye-controlled computer technology for nearly 20 years. But those devices have been primarily designed to aid those with disabilities, and are typically very expensive.

"After a while, we figured out that probably the best way is to go for a mass-market approach," says Gaze's Sune Alstrup Johansen. "Where everybody would have this available."

Johansen and some of his colleagues have formed a new company, The Eye Tribe, which is hoping to develop the technology on a mass commercial level.

The technology works by projecting an infrared light from the computing device toward the user's face. After calibrating with the user's eye movements, the technology is then able to easily detect where a person's eyes are moving, allowing the eyes to control a cursor.

"Our software can then determine the location of the eyes and estimate where you're looking on the screen with an accuracy good enough to know which icon you're looking at," reads an explanation on The Eye Tribe site.

There has been a gradual shift toward hands-free technology in recent years, particularly in the gaming world. On the heels of Nintendo's popular Wii system, Xbox released the Kinect device, which lets users control their Xbox and play certain games using only their hands, legs and voices. Still, most of these devices have been more of a gimmick than a practical alternative to using one's hands to control a mobile device.

While most smartphones and other mobile devices to not come standard with an infrared device, Johansen said a replaceable filter would be an inexpensive, convenient option for most consumers.

And even as companies like The Eye Tribe work to create a commercially viable product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

"Then I can go to any computer, and then I can control it and I can use it, instead of just bringing my own," said Stig Langvad, who heads up Denmark's umbrella organization for people with disabilities. "So I'll be a part of society on an equal foot, instead of being a special solution."
