AR Glasses Show Teachers Which Students Need Help In Class [Video]

The Augmented Lecture Feedback System (ALFs) uses AR to let students communicate privately with teachers without interrupting class. Developed by researchers from la Universidad Carlos III of Madrid, the system uses a pair of augmented reality glasses and a smartphone app.

Professors wearing the glasses can view icons displayed over the students’ heads during class. These different icons indicate whether they understand the topic or not, when they need the professor to slow down, or when they know the answer to a question. They are set by the students using an app connected to the system’s server.

The AR glasses enable the professor to quickly see what students want to communicate to them. They also enable them to send predefined questions to students’ phones and visualize notes or comments they want to mention at specific points.

Also, a diagram on the upper part of the glasses displays the aggregate of the answers given by the students, which can be useful with large groups. The main advantage of this system is that students can communicate with the professor immediately and privately, without interrupting the class, which could help those who feel nervous speaking in front of all their classmates.
