The
Uncanny Valley is something many people are aware of, but they can
never put a name to it. Do you enjoy pointing out the CGI in movies
that try to trick you into believing the CGI is real? Or do you feel
uneasy when you see something trying to mimic reality but it just
isn't quite right? This is the Uncanny Valley. Essentially the name
came from a dip in a graph created by robotics professor Masahiro
Mori, that stated when a robot (CG character) is created to look
lifelike but just misses the mark the viewer feels repulsed to look
at it. If something is sufficiently not lifelike then the lifelike
qualities will stand out to the viewer. On the other hand if
something is “almost lifelike” then it is the unlifelike
characteristics that stand out leaving you with a feeling of
repulsion or dislike.
Some
people say the Uncanny Valley cannot be beaten like Angela
Tinwell, senior lecturer in games and creative technologies at Bolton
University. "We've come up with the notion of the 'uncanny wall.
It suggests a viewer's discernment for detecting imperfections will
keep pace with technology. As the human likeness increases, so the
viewer becomes ever more discerning of little flaws. So when a new,
more "realistic" character like Tintin comes along, they
won't be rated as more humanlike – previous humanlike characters
will actually sink lower into the valley. It's cognitive dissonance;
we refuse to be tricked by technology."
Although
I agree with Tinwell that the viewer becomes more discerning of
little flaws as technology advances, I don't believe that the viewer
cant be deceived into thinking CG is reality. For example in Tron
Legacy (2010) the young Jeff Bridges was a CG character and fooled
many viewers. I believe this is because of three elements working
seamlessly together. Aesthetics, Movement and Environment. The
Visuals matched the rest of the film style so you didn't question his
character. The Movement was motion captured so that every detail was
relayed onto the CG character. And the environment matched the
character so the audience wouldn't question the placing.So as it has
obviously been achieved it isn't impossible...just difficult.
As
an animator I wanted to focus more on the movement side of the
combination because I believe that is where the personality and
emotion comes from in a character. I believe if animators and film
makers were more aware of the Uncanny Valley and what brought
characters into it then it would be easier to avoid falling in or
letting your audience drag you in. I explored both sides of the
Uncanny Valley, Abstract (Up, The Incredibles) and Realistic (The
Polar Express, Tin Tin, Avatar) to understand the differences in
workflow and restrictions between the two. I believe that through my
findings it will help inform and improve my quality of work and
understanding of animation. Through case studies and research, along
with practical experimentation, I have derived a variety of
guides/tips to help inform the animator of what puts a character in
the Uncanny Valley and what to do to stay out. These guides/tips are
by no means %100 fact but helpful processes to assist an animator on
his journey to create lifelike animations.
In
the second semester I wish to use these tips, along with the findings
my peers discovered in my group, to create something that will
deceive/trick the audience into believing or not noticing a CG
character thus proving 1, the guides/tips work and 2, It is possible
to deceive a well educated technological audience.
