Ⅴ Reading comprehension. 人与社会 科学与技术
Facial recognition technology(人脸识别技术) is widely used today. Now, a similar technology, known as facial detection(探测), is entering a new field: the business of advertising.
Such systems are going through tests in a small number of stores. One facial detection system can judge a person's "happiness" or "fear" level. That helps businesses see how people feel as they look at products or advertisements in the store. Another system can detect whether someone is wearing eyeglasses. If so, stores can send advertisements for new glasses to him.
Facial detection technology is also placed inside some large advertising boards. Cameras in those boards can detect information like people's ages and five levels of feelings—from "very happy" to "very unhappy".
Supporters of the technology say it could improve buyers' experience by showing products they might like or by offering them products at lower prices.
Some are against the idea of using such systems. The head of a privacy group thinks ▲. For example, a business could raise the price of a product according to a person's age and feelings.
However, one store testing the technology explained they wouldn't store people's information like names or ages. And the advertising board system maker said it didn't keep any personal information.
