Researchers at the University of WashingtonSeattle and at Sandia National Laboratories, in Albuquerque, have unveiled the latest advance in headâ''up displays: a contact lens with an imprinted electronic circuit and red LEDs. Future versions will superimpose images over the user’s view of the world and include wireless transceivers for two-way communication and solar cells for power. Now what’s to stop future generations of students from furtively scanning crib sheets when the illicit notes are on displays built into their contact lenses?
