Imagine a pair of glasses that project a virtual map as you walk down a new road, or turn your office into a gaming arena where you fight out zombies! A new patent application by Google could make it possible.
Google has published a patent application
for using holograms in a head mounted display like Google Glass, which could
create augmented reality experiences that superimpose computer-generated
imagery (CGI) over the real world.
Filed in March last year, the patent shows
Google's research into how it could merge its head mounted display technology
with augmented reality, 'Tech Crunch' reported.
To make smart eyewear more useful,
projected content must interact and react to the real-world behind it, rather
than just being pasted on top.
The new patent describes how Google could
potentially do this with augmented reality via holograms.
"With augmented reality the viewer's
image of the world is augmented with an overlaying CGI, also referred to as a
heads-up display," the patent said.
Head mounted displays (HMD) have numerous
practical and leisure applications. Aerospace applications could permit a pilot
to see vital flight control information without taking their eyes off the
flight path.
Public safety applications include
tactical displays of maps and thermal imaging. Other application fields include
video games, transportation, and telecommunications.
"There is certain to be new found
practical and leisure applications as the technology evolves; however, many of
these applications are limited due to the cost, size, weight, field of view,
and efficiency of conventional optical systems used to implemented existing HMDs,"
the patent said.
