Augmented reality is
the result of using technology to superimpose information — sounds, images, and
text — on the world we see. Picture the "Minority Report" or
"Iron Man" style of interactivity.
Augmented reality is
often presented as a kind of futuristic technology, but a form of it has been
around for years. For example, the heads-up displays in many fighter aircraft
as far back as the 1990s would show information about the attitude, direction,
and speed of the plane, and only a few years later they could show which
objects in the field of view were targets.
Google rolled out
Google Glass in 2013, moving augmented reality to a more wearable interface; in
this case, glasses. It displays on the user's lens screen via a small projector
and responds to voice commands, overlaying images, videos and sounds onto the
screen. Google pulled Google Glass at the end of December 2015.
As it happens, phones
and tablets are the way augmented reality gets into most people's lives. Vito
Technology's Star Walk app, for instance, allows a user to point the camera in
their tablet or phone at the sky and see the names of stars and planets
superimposed on the image. Another app called Layar uses the smartphone's GPS
and its camera to collect information about the user's surroundings. It then
displays information about nearby restaurants, stores and points of interest.
Some apps for tablets
and phones work with other objects as well. Disney Research developed an AR
coloring book, in which you color in a character in a conventional (though
app-compatible) book and launch the app on the device. The app accesses the
camera and uses it to detect which character you are coloring, and uses
software to re-create the character in 3D character on the screen.
One of the most popular
ways AR has infiltrated everyday life is through mobile games. In 2016, the AR
game "Pokémon Go" became a sensation worldwide, with over 100 million
estimated users at its peak, according to CNET. It ended up making more than $2
billion and counting, according to Forbes. The game allowed users to see
Pokémon characters bouncing around in their own town. The goal was to capture
these pocket monsters, then use them to battle others, locally, in AR gyms.
