In order to help the student expand his/her
knowledge I will help answer the question. This in hope that the student will
get a piece of knowledge that will help him/her through his/her homework or
future tests.
Google Glass uses a projector that bounces a
beam of light off a prism and projects the image directly on your retina. This was shown and explained
the day it was launched.
I hope
it helps, Regards.
