Is It Live or Is It AR?  By blending digital creations with our
view of the world, augmented reality is set to transform the way
we entertain and educate ourselves  There are two ways to tell
the tale of one Sarah K. Dye, who lived through the Union Army's
siege of Atlanta in the summer of 1864. One is to set up a
plaque that narrates how she lost her infant son to disease and
carried his body through Union lines during an artillery
exchange, to reach Oakland Cemetery and bury him there.  The
other is to show her doing it.  You'd be in the cemetery, just
as it is today, but it would be overlaid with the sounds and
sights of long ago. A headset as comfortable and fashionable as
sunglasses would use tiny lasers to paint high-definition images
on your retina--virtual images that would blend seamlessly with
those from your surroundings. If you timed things perfectly by
coming at twilight, you'd see flashes from the Union artillery
on the horizon and a moment later hear shells flying overhead.
