While the prototype glasses currently look rather goofy, it is hoped that the system could ultimately be integrated into a sleeker device such as Google Glass
An experimental set of augmented reality glasses allow professors to see if any students aren't following what they're saying

It must be hard for university professors ... they tell their students to shout out if they don’t understand what’s being said in a lecture, yet few students are likely to feel comfortable raising their hand in front of the class and saying “I don’t get it.” Scientists at Spain’s la Universidad Carlos III de Madrid are hoping to address that situation, with a set of augmented reality glasses that let profs see who’s “not getting it,” without those students having to say so verbally.
