As Connor reports, the teacher, Wei Xiaoyong, actually started using facial recognition technology in the classroom five years ago, as a more effective means of tracking student attendance. Now, he has adapted the technology so that it scans for signs of whether students are in a neutral or happy state of mind, which could suggest when they are bored and help him to refine his lessons and teaching style. (Wei is, of course, a science teacher.)
The equipment used by the teacher isn’t specified, but an accompanying image depicts Wei standing next to a Mac monitor displaying an image of his classroom and students, suggesting that he is using readily-available computer cameras outfitted with biometric algorithm software.
It’s another example of the growing preponderance of biometric technology, with facial recognition being perhaps particularly widespread in China; the country’s major mobile payments app, Alipay, uses facial recognition technology to authentication users, for example. But Wei’s example also demonstrates a particular niche application of this technology, helping to illustrate its versatility.
