If a potential customer enjoys your advert, they are more likely to buy your product.
如果潜在的客户欣赏你的广告，那么他们会更有可能去购买你的产品。
It's a simple enough concept, but it is extremely difficult to know how well your advert is being received in the real world.
这是一个相当简单的观点，但要想知道你的广告在现实世界中是否能被人们所接受是非常困难的。
Now a new system could help advertisers know exactly how their latest offering is going down with viewers, just by watching their face.
目前，一种新型的系统可以帮助广告商通过观察观众的脸来准确地判断出他们最新的产品是否能被接受。
The system, developed by Daniel McDuff and colleagues at the Massachusetts Institute of Technology Media Labs, looks at how muscles in the face move in response to watching a video.
这个系统是由美国麻省理工学院媒体实验室的丹尼尔·麦克达夫和他的同事所开发，主要是对观众观看视频时脸上的肌肉变化进行研究。
Software can then classify what counts as positive facial responses and smiles during the video and from that predict which adverts the viewer most enjoys.
该系统可以对观众积极的面部反应和微笑进行分类，预测出哪些广告最受欢迎。
The team collected more than 3200 videos of people, whose faces were filmed by their own computer's webcam as they watched three adverts online during the Super Bowl in 2011.
该研究团队收集了超过3200部视频，这些视频记录了人们的脸部表情。当人们观看2011年美国橄榄球超级杯大赛期间的三个在线广告时，他们的脸部表情被他们自己电脑上的摄像头进行了拍摄。
After each commercial—one for Doritos, one for Google and one for Volkswagen—the viewers were asked if they liked the video and whether they would want to watch it again.
三个广告分别关于多力多滋、谷歌、大众汽车。在观看完三个广告后，观众被问及他们是否习惯这些视频，是否想再看一次。
In tests, the system made correct predictions more than 75 percent of the time.
在测试中，该系统的准确预测率超过了75%。
The system would be a boon for advertisers trying to grab the attention of potential customers on the internet.
该系统有利于广告商在互联网上抓住潜在顾客的注意力。
In future, the system could be used to personalize adverts for viewers as they watch programmes online, depending on their reaction, or as a more effective way of testing how good a new advert is at appealing to customers.Thank you.
在未来，该系统可以根据人们观看在线节目时的反应，或者作为测试一个新广告如何有效吸引顾客的方式来为观众制作个性化的广告。谢谢。
