AR Glasses Show Teachers Which Students Need Help In Class [Video]
The Augmented Lecture Feedback System enables kids to communicate privately with teachers without interrupting the lesson.
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.
