Please listen and respond to each question truthfully, please answer
clearly and loudly, please try not to move your head and shoulders during the
interview so that the sensors will not be affected.
What does a lie look like? It's hard to tell if you're human.
On average, people don't do much better than a coin flip.
The researchers at Michigan Engineering are banking on computers to help sniff out
deception. They're building unique lie detecting software. They've already
identified some common tells: liars tend to scowl or grimace more than
truth tellers, they talk with both hands, they often distance themselves
from the action with words like He or She instead of I or We and, a bit counter
intuitively, lying liars look their questioners in the eye
a bit more often than those presumed to be telling the truth. You can make a note
of these things for next time you're at the poker table, the researchers though
have bigger ideas.
Deception is an important prevalent phenomenon in everyday life and I think it also has
important application in law enforcement security. Imagine you have police scanning you when
they have like a body camera, they stop somebody and the machine will tell you there is a 75
chance that this guy is lying to you...how useful is that
To make their prototype software,
the researchers trained their computers on a set of a hundred and twenty videos from
actual court trials. They did that for a couple reasons, for one, they could
confirm who was lying based on trial outcomes and also the environment showed
real behaviors when the stakes were highest. Gestures such as lip and head
movement as well as speech patterns, even individual words were analyzed to create
modalities or information channels that they could then compare. Now they're
adding another layer, they're testing thermal imaging cameras and sensors that
can read a subject's breathing rate and temperature from their forehead, face and
upper body. A mixture of a hundred male and female subjects from different
cultures will be tested using the new setup. Are the lights on in this room?
Yes.
Regarding that missing bill do you intend to answer each question truthfully about
that? After all the sensors are connected, the researchers hand the subject a $20
bill. She could either
pocket it or put it back in a concealed box. No one else will know
where the money is hidden. It's up to the software to decide if she's telling the
truth. Let's say you steal 20 bucks then you can keep the 20 bucks if you don't
get caught, if you get caught - you don't get the $20. In your case, I think you're
saying the truth...yes I am. While they're aiming for an even higher hit rate, so far the software
can pick out a phony 75% of the time...
honest.
However, if you have optogenetics then you can genetically modify neurons
in a way that some specific target cells are only responding to a wavelength...different colors.
So we are developing the next generation...
