Recently, a group of Spanish engineers created a pair of glasses that allows teachers to maintain mental communication with their students during class.
These so-called “increased reality glasses” allow the teacher to visualize symbols on top of every pupil’s head, which indicate if the pupil is understanding the explanation or not, if they know the answer, if they need the teacher to talk more slowly, and so on. The students are the ones whom, through their mobile phones, activate the symbol according to what they are understanding.
Teachers can also use these glasses to store and look at their notes and brainstorming.
The advantage of these glasses is that it allows direct contact between the teacher and each of the students without having to interrupt the class or modify explanations based on the reaction of the students, “this allows classes to be more productive”, say the group of engineers.
“This channel that we’ve created can be used to overcome problems of students who are shy or are scared of expressing themselves in front of the class”, commented Ignacio Aedo, a teacher at the Carlos III University of Madrid.
The glasses were tested at the Carlos III University in the Spanish capital and despite the fact that it is public, the classes at the university are quite small in size, therefore I have my doubts on how well these glasses would work with bigger numbers of students, but I suppose we shall have to wait and see to find out.
