Would You Wear These Glasses to Teach?

Researchers at a Spanish university, la Universidad Carlos III of Madrid, have unveiled special intelligent glasses for use by professors when teaching. The glasses have multiple views for the professor, who can see notes for lecture delivery while wearing them. Further, the professor can look at students and then a symbol will appear -- selected by the student -- to indicate whether the student understands the content, and whether the student would like the professor to slow down. The professors who invented the glasses said that they would eliminate the need for a student to make a public statement about not understanding lecture content.
