Another interesting use-case for wearable AR systems like Google Glass comes from a Spanish university that has integrated it into a lecturer system for monitoring classroom participation.

Researchers at la Universidad Carlos III de Madrid have developed the Augmented Lecture Feedback System (ALFs), a HUD glasses interface that teachers can wear while giving a lecture. From the display, teachers can see little icons that appear above each student’s head, indicating their comprehension of the given lesson as well as an overall chart indicating how many students are “getting it” compared to the rest of the class. The symbols the system supports also include a request for the lecturer to slow down, and a notification that a student knows the answer to a question posed in class.
