Are Your Students Bored? This AI Could Tell You

A professor finishes a lecture and checks his computer. A software program shows that most students lost interest about 30 minutes into the lecture—around the time he went on a tangent. The professor makes a note to stop going on tangents.

The technology for this fictional classroom scene doesn’t yet exist, but scientists are working toward making it a reality. In a paper published this month in IEEE Transactions on Visualization and Computer Graphics, researchers described an artificial intelligence (AI) system that analyzes students’ emotions based on video recordings of the students’ facial expressions.

The system “provides teachers with a quick and convenient measure of the students’ engagement level in a class,” says Huamin Qu, a computer scientist at the Hong Kong University of Science and Technology, who co-authored the paper. “Knowing whether the lectures are too hard and when students get bored can help improve teaching.”
