This could be amazing. Clive Cookson for the Financial Times:
The technology, being developed at Massachusetts Institute of Technology and the University of California, Berkeley, essentially “puts the glasses on the display, rather than on your head”, says Gordon Wetzstein of MIT. “It will not be able to help you see the rest of the world more sharply, but today we spend a huge portion of our time interacting with the digital world.”
As someone who's had to wear glasses for the past 15 years, this is exciting. Not having to wear glasses while at the desk or reading the iPad in bed would be amazing.
Think what else it could do: deter thefts and make it harder for people to snoop.
