In ancient Greek fairy story， Medusa’s stare turns onlookers to stone. Yang Shuo， a junior software major at Wuhan University， can cut fruit in the Fruit Ninja game（水果忍者游戏） 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 open up 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 caught 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 hardest problems，” said Yang， leader of the team named “Xight”.
Li Jin， 21，英语毕业论文， a junior software major at the university， found a challenging problem during his visit to Chongqing Disabled Person’s Federation in an off-school activity last year. Li noticed that disabled people wanted to communicate through 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. For 20 days they worked wearing a neck brace before they finally met with success with a head localization algorithm（运算法则）， which can exactly locate the target and carry out commands.
In the US， software and digital glasses with a similar function cost $8，000. But Xight’s can be much more competitive if put into the market.
“Even if we perfect the appearance of the glasses and the function in a more user-friendly way， it won’t cost more than 500 yuan，” said Yang. “At present， our focus is to improve Xight and make it an ideal application for disabled people. When we achieve this， we’ll consider making our invention a big business，” said Yang， who has been busy preparing papers and materials for Xight’s patent application（申请专利）.
“One day， when you return home， you will tell the computer to dim the light， use a hand gesture to turn on the TV and glance at the air conditioner to lower the temperature，英语论文题目，” said Yang.

【难句解析】
1. The aim is to help physically challenged people and possibly to open up a new area in computer control technology. 这项发明旨在帮助残障人士，并可能开拓计算机操控技术的新领域。
整个句子是简单句，主语是the aim，is是系动词，表语由两个动词不定式并列充当。注意第二个动词不定式理解时要注意。它的主语实指the invention，而不是aim，这种现象在语言中也是常见。be to open up...在第二部分中含有“一定会开拓……”的意思。
2. Their eye movement is caught by digital cameras fixed to the glasses， enabling the eyes to act like a computer mouse. 固定在眼镜上的数码相机能够捕获用者的眼球运动，这样一来双眼就可以代替电脑鼠标的功能。
这也是一个简单句。主语是their eye movement is captured by cameras是谓语部分，为被动语态，fixed to the glasses是过去分词作定语修饰cameras，相当于定语从句which are fixed to the glasses， enabling是现在分词作结果状语。
3. However， the team discovered that eyes can be too quick to be captured by camera for an accurate positioning function. 但是该团队发现眼球运动太快，相机难以捕捉其运动状况，无法实现精确定位功能。
这是一个复合句，主句主语the team，谓语discovered 后接宾语从句。宾语从句中主语是eyes， can be too quick to be captured是谓语，too... to...太……而不能……，for/名词短语表示目的，相当于to position accurately。 |
