SHANGHAI – A Chinese university is using facial recognition technology to track attendance of students in classrooms, official news agency Xinhua reported on Wednesday.
“The traditional way of tracking attendance is through a roll call. The new system saves time and reduces the workload of teachers,” said Shen Hao, professor at the Communication University of China in Beijing.
Shen, who is one of the first teachers to adopt this technology, uses it in his six courses to track the attendance of more than 300 students.
Shen activates the new attendance system, installed on his tablet, before he starts his classes.
Students stand in front of the screen one by one to get their photos taken and matched with those in the school database.
The system is based on facial recognition technology of the open Artificial Intelligence platform of the Chinese internet giant Baidu.
According to data from China’s Forward-looking Industry Institute, the facial recognition market in China surpassed 1 billion yuan (about $150 million) in 2016 and is expected to reach 5.1 billion yuan by the year 2021.
