导读：你能想象戴上眼镜，动动眼球便可以“切水果”吗？由武汉大学大三学生团队研发的Xight人眼视线捕捉系统将神话(mythology)变为现实。

In ancient Greek mythology, Medusa's gaze turns onlookers to stone. Yang Shuo, a junior software major at Wuhan University, can crush fruit in the Fruit Ninja game simply by moving his eyes. The 21-year-old and his teammates recently developed a mask which operates a computer by eye movement.

The aim is to help physically challenged people and possibly to pioneer a new area in computer control technology. Their product enables users, who have weak muscles or are disabled, to operate a computer.

Their eye movement is captured by digital cameras fixed to the glasses, enabling the eyes to act like a computer mouse.

"We wanted to develop a technology that helps others and solves the toughest problems," said Yang, leader of the team named "Xight".

Li Jin, 21, a junior software major at the university, found a challenging problem during his visit to Chongqing Disabled Person's Federation in an off-campus activity last year. Li noticed that disabled people wanted to communicate via the Internet, but many were unable to because of their physical condition.

"Let's see what we can do," said Yang.

The idea of using the eyes to control a computer came up. "Because the eye is one of the most agile parts of the human body," said Li.

However the team discovered that eyes can be too quick to be captured by camera for an accurate positioning function.

As a result, their prototype glasses could only function in four corners of a computer screen with the head held still, which wasn't practical.

The team reckoned that with lots of experiments and calculations, a pattern of eye movement could be traced and programmed.
