你能想象戴上眼鏡，動(dòng)動(dòng)眼球便可以“切水果”嗎？由武漢大學(xué)大三學(xué)生團(tuán)隊(duì)研發(fā)的Xight人眼視線捕捉系統(tǒng)將神話(mythology)變?yōu)楝F(xiàn)實(shí)。

　　In ancient Greek mythology, Medusa’s gaze turns onlookers tostone. Yang Shuo, a junior software major at Wuhan University, cancrush fruit in the Fruit Ninja game simply by moving his eyes. The21-year-old and his teammates recently developed a mask whichoperates a computer by eye movement。

　　在古希臘神話中，美杜莎可以用目光將看到她的人變成石頭。而來自武漢大學(xué)軟件專業(yè)的大三學(xué)生楊碩在玩水果忍者游戲時(shí)，卻可以通過移動(dòng)視線來切水果。最近這位21歲的大學(xué)生和隊(duì)友們共同研發(fā)出了一個(gè)通過眼球運(yùn)動(dòng)來操控電腦的面具。

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

　　這項(xiàng)發(fā)明旨在幫助殘障人士，并極有可能開創(chuàng)計(jì)算機(jī)操控技術(shù)的新紀(jì)元。他們的產(chǎn)品可以幫助那些肌無力或身患?xì)埣驳氖褂谜邅聿僮麟娔X。

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

　　固定在眼鏡上的數(shù)碼像機(jī)能夠捕捉用戶的眼球運(yùn)動(dòng)，這樣一來雙眼就可以代替電腦鼠標(biāo)的功能。

　　“We wanted to develop a technology that helps others andsolves the toughest problems,” said Yang, leader of the team named“Xight”。

　　“我們希望開發(fā)一種技術(shù)，可以幫助他人解決最棘手的難題?！薄癤ight”團(tuán)隊(duì)隊(duì)長(zhǎng)楊碩稱。

　　Li Jin, 21, a junior software major at the university, found achallenging problem during his visit to Chongqing Disabled Person’sFederation in an off-campus activity last year. Li noticed thatdisabled people wanted to communicate via the Internet, but manywere unable to because of their physical condition。

　　21歲的李今同樣是武大軟件專業(yè)的大三學(xué)生。他在去年參加參加重慶殘聯(lián)的校外活動(dòng)期間發(fā)現(xiàn)了一個(gè)極具挑戰(zhàn)性的難題。李今注意到，盡管殘疾人士希望通過網(wǎng)絡(luò)與外界溝通，但很多人因?yàn)樯眢w狀況而無法實(shí)現(xiàn)這一想法。

　　“Let’s see what we can do,” said Yang。

　　“讓我們來看看自己能做些什么?！睏畲T說。

　　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。

　　于是，他們想到了用眼睛來控制電腦?！耙?yàn)檠劬κ侨祟惿眢w上最靈活的部分之一?！崩罱裾f。

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

　　但該團(tuán)隊(duì)發(fā)現(xiàn)眼球運(yùn)動(dòng)過快，相機(jī)難以捕捉其運(yùn)動(dòng)狀況，無法實(shí)現(xiàn)精確定位功能。

　　As a result, their prototype glasses could only function infour corners of a computer screen with the head held still, whichwasn’t practical。

　　因此，他們?cè)戎谱鞯难坨R原型只有在保持頭部不動(dòng)的情況下，控制電腦的四個(gè)角，缺乏實(shí)用性。

　　The team reckoned that with lots of experiments andcalculations, a pattern of eye movement could be traced andprogrammed。

　　他們思考后認(rèn)為，通過大量的試驗(yàn)和計(jì)算，可以追蹤眼球運(yùn)動(dòng)的方式，并編寫相關(guān)程序。

　　For 20 days they worked wearing a neck brace before theyfinally made a breakthrough with a head localization algorithm,which can accurately locate the target and execute commands。

　　他們頭戴頸托工作了20天，終于取得了突破，研究出一個(gè)可以準(zhǔn)確定位目標(biāo)、執(zhí)行命令的頭部定位公式。

　　“Many times when I took off the neck brace, I felt that it washard to move my eyes and my neck was killing me,” said Yang. “Butit was worth the pain?！?/P>

　　“有好多次我摘下頸托，發(fā)現(xiàn)眼睛都動(dòng)不了了，脖子也疼得要命?！睏畲T說，“但是這些痛苦都值得?！?/P>

　　Xbox experts were excited to learn that Xight was even quickerthan hand-waving karate moves when playing Fruit Ninja at anational competition sponsored by Microsoft. Mark Taylor, directorof Development and Platform Evangelism Group, is amazed by thepotential of Xight’s work。

　　在微軟贊助的一項(xiàng)全國(guó)性競(jìng)賽中，Xight視線追蹤系統(tǒng)在水果忍者游戲中的動(dòng)作甚至比空手道中的揮拳動(dòng)作還要迅速，Xbox專家們?cè)诘弥撓⒑笈d奮不已。微軟大中華區(qū)開發(fā)工具及平臺(tái)事業(yè)部主管馬克•泰勒對(duì)Xight的潛力感到十分震驚。

　　“This product not only showcased technical brainpower but alsoa promising market perspective,” said Taylor。

　　“該產(chǎn)品不僅展現(xiàn)出技術(shù)智能，更展示出了很好的市場(chǎng)前景?！碧├照f。

　　Taylor is right。

　　泰勒說的沒錯(cuò)。

　　In the US, software and digital glasses with a similarfunction cost $8,000. But Xight’s can be much morecompetitive。

　　在美國(guó)，擁有類似功能的軟件和數(shù)碼眼鏡售價(jià)高達(dá)8000美元。而Xight的價(jià)格更具競(jìng)爭(zhēng)力。

　　“Even if we refine the appearance of the glasses and thefunction in a more user-friendly way, it won’t cost more than 500yuan,” said Yang。

　　“即使我們?yōu)榱颂岣哂脩趔w驗(yàn)度，而改善眼鏡外觀及其功能，它的成本也不會(huì)超過500元?！睏畲T說。

　　Many investors have already contacted the team trying to putthe invention into commercial production. But the teamrefused。

　　許多投資商紛紛找到Xight團(tuán)隊(duì)，試圖將該發(fā)明投入商業(yè)生產(chǎn)，但都被婉拒了。

　　“At present, our focus is to improve Xight and make it anideal application for disabled people. When we achieve this we’llconsider commercializing our innovation,” said Yang, who has beenbusy preparing a thesis and materials for Xight’s patentapplication。

　　“目前，我們的重點(diǎn)是改進(jìn)Xight，使它成為殘疾人士的理想應(yīng)用。當(dāng)我們成功之后才會(huì)考慮將發(fā)明成果商業(yè)化?！睏畲T說。他正在為Xight申請(qǐng)專利準(zhǔn)備論文及相關(guān)材料。

　　Not surprisingly, the team won the top prize in the innovationcompetition and will represent China at the worldwide innovationchallenge to be held in Sydney, Australia, next month。

　　不出所料，Xight團(tuán)隊(duì)最終贏得了該創(chuàng)新競(jìng)賽的特等獎(jiǎng)，并將于下個(gè)月代表中國(guó)參加在澳大利亞悉尼舉辦的全球創(chuàng)新挑戰(zhàn)賽。

　　The four are racking their brains to incorporate new elementslike gesture control and voice control in Xight to spice up thehuman-machine interface concept。

　　目前，四位成員正在絞盡腦汁為Xight配備手勢(shì)控制和聲音控制等新元素，為人機(jī)互動(dòng)理念加些新料。

　　“One day, when you return home, you will tell the computer todim the light, use a hand gesture to turn on the TV and glance atthe air conditioner to lower the temperature,” said Yang。

　　“未來有一天，回家后你可以用語音指令指揮電腦調(diào)暗燈光，用手勢(shì)打開電視，看一眼空調(diào)就能調(diào)低溫度?！睏畲T說。
