ADVANCED TECHNOLOGY

摘要

Head-mounted and other virtual displays are nothing new, but they usually are noncontact entities. Now engineers at the University of Washington are developing what may turn out to be a major contribution to "information overload:" contact lenses imprinted with electronic circuits and lights. The goal is to allow the wearer to see a generated image super-imposed over the outside world. Researchers cite many possible uses, including navigation information for drivers or pilots, virtual reality for video games, and Internet surfing while you go about your daily business. According to researcher Babak Parviz, "People may find all sorts of applications for it that we have not thought about. Our goal is to demonstrate the basic technology and make sure it works and that it's safe."
