What We Can See with Augmented Reality | Ethan Edwards | TEDxColumbiaUniversity


I’m an artist and often artists have
been concerned with images more
specifically I’m an artist who works
with technology things like laptops and
smartphones they’re things we haven’t
come up yet because I’m interested in
the future of images and what of those
we’ll look at images can really shape
the embody what we know and they can
actually come to define what we know and
what we understand about the world as an
example take this map of the world made
by anonymous artisans in medieval
England and is now crucial to our
understanding of how medieval Europe saw
itself Jerusalem is at the center the
oceans are a strange ring and there’s
all sorts of fantastic beasts and places
from the Bible here we’re much more
familiar though with a map that looks
like this our understanding of geography
has changed a lot now this is supposed
to be accurate there’s nothing in
particular in the center and we can use
this for navigation nation states have
very careful borders however a lot of us
probably haven’t used a map like this
recently we’re more familiar with
something like this now we’re at the
center with a blinking blue dot and we
can zoom and rotate based on where we
are where we want to go and it’s no
longer in a piece of paper it’s on our
laptop screens it’s in our phones in
fact many of us probably used such a map
to get here today and it’s amazing how
these changes in our understanding and
these changes in technology can really
redefine the way our images look as well
as the way we interact with them as
another example take medicine our
understanding of the human body has
transformed so much and with that the
images we use to understand what’s going
on as well as the images we use to teach
people you can also look at architecture
where the images that we use to plan and
design these buildings embody the values
that go into the construction of it the
fundamental design principles that are
building these things images contain
within them a way of life we put our
understanding into images we copy them
we use them to teach we spread them
around we learn from them our ideas are
defined by them and that goes on until
the next person comes along and creates
the next set of images what I’d like to
ask today is what’s coming next what is
the next step for images well I don’t
know and I’d be lying if I said I did
but I have a guess and my guess is that
it’s going to involve this technology
called augmented reality or AR the short
version of the story is that a bunch of
different camera and computer technology
has advanced to the point where not only
can we represent the world but we can
actually change what we’re seeing in it
we can put things that weren’t really
there and change our view of things a
particularly famous example of this
would be Pokemon Go which all around the
world people downloaded it and it
fundamentally changed the way they
interacted with their environments
there’s many many different
organizations and companies that believe
that this is the next step in images and
organizations like snapchat the New York
Times are investing in this exploring
what they can do with it because they
think that this is what’s coming and
that how we use our devices how we
interact with the world will in some way
be shaped by this technology also
augmented reality has many practical
purposes if you look at construction at
architecture these sorts of applications
where you can directly see what you’re
doing where you no longer have to look
down at a pay
extremely helpful they improve
efficiency in an incredible way and
really could redefine how some of these
industries function there’s all sorts of
companies which are taking sort of older
outdated imagery and trying to figure
out what the future is going to look
like how we can use these more
efficiently to teach to learn to
understand augmented reality is also
very different from the sorts of
historical examples I’ve given this
isn’t a chart or a map on the page which
you can kind of look at and then put
down these are increasingly in our
phones which we carry with us everywhere
they’re coming very quickly – glasses –
contact lenses – things that were
wearing all the time
maybe two devices we haven’t yet thought
of and that’s incredible these images
are going to be in our world they’re
physically there and they’re redefining
how we perceive our everyday lives all
this comes with a danger though if these
images will truly be present in our
world and if they truly will come to be
part of how we understand things whose
images will they be recently we’ve all
had to think a little bit more about the
role that social media plays in our
lives and whether these sorts of
technological developments are actually
good for society or not and if we look
to science fiction we can see some
pretty scary examples of what augmented
reality might look like if you can
imagine one person having control of how
every map looks or one organization
being able to find how we understand our
own bodies that can be very dangerous
there’s no doubt going to be a lot of
money and power involved with the
control of augmented reality so surely
people will say kit so is this
technology going to be used to make us
more human to change the way we see each
other for the better or will it be used
for isolation for division and for
solidifying the current power structure
that we already have
the first step to fighting something is
to understand it and the best way to
avoid being fooled by a sophisticated
and scary hologram is to have already
seen behind the curtain about what’s
going on and understand the process that
goes into it and that’s really what I’d
like to convey today that the fortunate
thing about augmented reality is we
haven’t yet really figured any of it out
the fundamental technology behind it is
largely free there are many many
tutorials on the internet and there’s a
lot of experimentation that is still
going on a whole bunch of independent
artists have started experimenting with
this technology seeing what is newly
possible what things might look like and
no one has quite figured it out yet no
one has figured out how with augmented
reality you tell a story you make an
argument you communicate with someone or
if you see yourself and that’s what’s so
exciting this is our opportunity to
really define what these next images
will look like to really take control of
it for ourselves
to determine how we as a society will
see things now here’s the time when you
can pull out your phones I have some
instructions but if you pull it out if
you have one of the newer iPhones and
click on that viewer option and look
towards the stage you’ll see what I’m
talking about and the big thing is that
if you look down in the bottom right
corner I have put all the code for this
app everything that went into it online
for free because I want everyone to be
able to change this to modify it to make
something new with it to destroy it to
ruin it to change how everything really
functions with it to do something with
for those of you who can’t see hopefully
we can get it up on the screen augmented
reality is already coloring our world we
have an amazing opportunity right now to
really determine how our society will
see ourselves to see everything in the
future let us take this power let us
celebrate it and let us together write
the next chapter in the history of
images let us go forward chase in color
take it downloaded and do whatever you’d
like with it thank you [Applause]
