Recently, Hangzhou No. 11 Middle School has piloted the Smart Eye system, which installs a combination of cameras in the classroom to capture students' expressions and movements in class. With the help of facial recognition technology, it collects students' 6 types of classroom behaviors and 7 types of classroom expressions.
The school believes that this measure can help teachers accurately grasp the teaching effect and adjust the teaching method in time. However, netizens obviously do not buy it, believing that this violates the privacy of students, and some netizens ridiculed this behavior as a real-life version of "1984".
The teaching system that caused a stir is called the "Smart Classroom Behavior Management System", or "Smart Eye" for short.It is said that it can accurately capture studentsRead, stand up, raise your hand, lie on the table, listen and writeAnd other 6 behaviors, combined with the students' facial expressions to analyzeNeutral, happy, sad, angry, scared, disgusted, and surprised7 emotions.

The hardware part consists of a rotatable camera and a facial recognition device. There are about three in each classroom, which scan every 30 seconds.
Smart Eyes - The student who loves to tell tales the most in the class
After the information is simply processed by the system, a string of codes will be generated, such as listening carefully to the class is A, lying down to sleep is B, answering questions is C, and the status of the students will be judged based on this. A good status, such as listening carefully to the class, will add points, and a bad status, such as sleeping in class, will deduct points.
These data will be directly pushed to the teachers after class, so that they can understand the classroom effect and students' reactions. Teachers can use this to optimize their teaching methods, and schools can also use it to judge the quality of teachers' teaching.
However, due to the presence of cameras, it is inevitable that students will feel a little uncomfortable, which is understandable.
As for the privacy and data leakage issues that the public is concerned about, it is said that the data information generated by this system is only accessible to teachers and school leaders, and other teachers or non-school personnel are not allowed to view it. Moreover, all cameras are only used to collect behavioral information, not for monitoring or recording, so there is no privacy or data leakage issue.
The 11th Middle School plans to install the system in all classrooms this year, which can monitor students' emotions in class and record their attendance by face recognition. However, the system is still in its early stages and needs more data for it to learn and improve the accuracy of emotion recognition.
In the future, they plan to replace all card swiping in the school with face scanning, creating the country's first cardless campus. I wonder if this was inspired by Alibaba's Jack Ma next door.
Classroom monitoring may be a good thing
Hangzhou No. 11 Middle School is the first to bring high technology to campus, but we hope that the school will not use emotion recognition, which is used to improve teaching quality, as a real-time monitoring tool. After all, even though the campus is a public place, every student should still retain some personal privacy within certain limits.
Ultimately, the reason why the Smart Eye system has attracted attention and discussion is because people feel that students are being monitored. But think about it the other way around, Smart Eye claims that data is not stored or made public, which is actually similar to the traditional teacher's eyes.
Therefore, the most important thing is the "User Agreement". What the school should clarify now is the usage and authorization scope of the video content in Huiyan.
Emotion recognition: can be more meaningful
There are more and more application scenarios for emotion recognition, thanks to the rapid development of AI technology.
Of course, the students at No. 11 Middle School may not be grateful to AI. Instead, they can refer to how the United States is making a fortune using emotion recognition.
Movie watching
Caltech and Disney have jointly developed an emotion recognition system that uses facial expression tracking neural networks to accurately predict the audience's reaction to the next plot. Later, this system was used to observe the crowd, understand more complex visual data, and help care for the disabled.
When shopping
Two years ago, Apple acquired an emotion recognition technology company, Emotient. It is said that the emotion recognition program they developed optimizes ads and improves conversion rates by observing the audience's emotional changes in ads. No wonder AppStore ads are becoming more and more interesting.
While driving
In Massachusetts, Affectiva's emotion recognition program is also very advanced. It can directly connect to the in-vehicle intelligent system to assist your driving behavior by analyzing your emotions while driving, thereby improving driving safety and comfort.
For example, when you are driving alone and tired, it will remind you to pay attention to the road ahead. If your car is advanced enough, you don’t need to actively turn on the automatic driving switch, it can actively help you drive, and maybe you will reach your destination when you wake up.
Therefore, since there are so many meaningful usage scenarios, we can temporarily let high school students go.
