and how do we help people  communicate emotion,

at work, for your customers,  for your kids at school?

Our challenge at The MIT Media Lab  and at Affectiva,

to measure and help people  communicate emotion.

I'll start with an example  that we did years ago

that we gave to an audience like you, worn on the palm of the hand

the audience got excited.  Every time they were engaged.

We learned for example  that every time a new speaker

Every time there was a live demonstration,

whether it worked or not,  the audience glowed.

Every time there was live Q&A or laughter,

the audience glowed  but unfortunately, every single time

there was a decaying exponential  in brightness.

Here, for a nine year old boy, watching a movie trailer,

the signal will go up about a second  after each of the parts of the trailer

See this is where it  kind of falls of here though.

He peaks for the name of the movie  and the date of it,

so you can see why people  in Market Research and Advertising

are extremely interested in this information

or I as an educator,  I'm extremely interested too.

is connecting with my students  and with my loved ones.

Here's an example of the signal  changing with a Patriots fan,

back when the Patriots  were in the Superbowl.

And this one illustrates an important point  about skin conductance

and that is even as we measure  the auto-immunic arousal

This goes up with things  that are good or bad.

So we see it go up here  when the guy has a --

when his favorite team  scores a touchdown,

it also goes up  during an endzone overthrow.

Interestingly, it also goes up  during a Dorito's Mouse T.V. commercial,

when the mouse comes out  and catches the man.

It's interesting now that we can get  this information in real life,

to see how relatively important  different events are in life

and where the significance of something  that you share with somebody,

compares with this response to some other things  that are going on with their life.

This skin conductance is driven  by the autonomic nervous system,

Your autonomic nervous system  has two main branches,

The sympathetic can be thought of kind of like  stepping on the gas, in the car,

it revs your heart up, it causes  the skin conductance to increase.

The parasympathetic causes the heart to decrease.

The sympathetic is thought of  as fight or flight,

Almost all the organs are innervated by both  the sympathetic and the parasympathetic,

except the skin,  which gets the pure sympathetic,

which makes it ideal for us measuring  this fight or flight response.

Now, I became interested in measuring this response when I started working a lot

with people in the autism spectrum,  who are non-speaking.

The most heart-breaking stories,  that I hear from these --

from the families  and the individuals themselves,

when they later acquire  the ability to speak,

is that, the changes that were worst,  were when they got kicked out of school

removed from learning opportunities  and social opportunities.

Usually it was a meltdown  or a series of meltdowns

and the meltdowns, like adult tantrums,  appear to come from nowhere.

One moment the person seemed calm and relaxed,

the next moment they might have become injurious

So, they seemed very unpredictable  and uncontrollable.

Now, as we undertook the privilege  of getting to know some individuals

who could later communicate,  they told us that these meltdowns

never came from nowhere that, in fact, they were always preceeded

They couldn't understand why people  couldn't see what was bugging them.

So this made me think, "Wow, what if we could enable them

to signal out their increasing stress  and frustration?"

But to do that required a device  that is shown on the left here,

skin conductance  sympathetic nervous system measure,

and that was uncomfortable  to wear in daily life.

So my team at MIT went through  lots of iterations
