  • There are a lot of us. All with different cultures, languages, beliefs.

  • So, yeah. Communication. It's not always easy.

  • You're crazy.

  • You're crazy.

  • You're crazy

  • (slapping)

  • But no matter where we come from or the languages we speak, by using these, we can still connect with other humans.

  • And now maybe with them too.

  • There are so many purposes of facial expressions.

  • I'm David Matsumoto. I'm a Professor of Psychology at San Francisco State University, and I'm also director of Humintell.

  • The face is one of the most complex signal systems we have in the body.

  • And it serves many purposes.

  • For example, when we wrinkle our nose in disgust like this,

  • not only is it communicating something to you who can perceive my expression,

  • what is also doing is clamping down a little bit on those nasal passages.

  • It's preventing things from coming into my body, through my nasal passage.

  • Facial expressions also communicate to the people around us.

  • One of the biggest advocates for this theoryCharles Darwin.

  • Darwin posited that all humans have emotions.

  • It allows us to act immediately with minimal conscious thinking or awareness.

  • And then on top of that, we add these expressions so that we could communicate that reaction to others as well and that helped the group to survive.

  • Because of this, Darwin believed our expressions were universal.

  • So in psychology today, there is widespread agreement that seven facial expressions of emotion are universally recognized all around the world,

  • regardless of race, color, creed, nationality, gender, any demographic that exists.

  • They are: anger, contempt, disgust, fear, happiness, sadness, and surprise.

  • So this means as humans, we can talk to each other, even without words.

  • But can facial expressions help us connect with humanlike technology?

  • So the robot is a way to understand human self, for me.

  • By creating the very humanlike robot, I believe that we can get some knowledge about the humans.

  • My name is Hiroshi Ishiguro. I'm a roboticist.

  • What I could learn through the robots (are) so many things, right?

  • We are trying to develop interacting robots with humans.

  • And we're studying the how the human can interact with the robots.

  • So in order to develop that kind of a robot, the first facial expressions, and the gazing directions, gazing control of the robot is so very important.

  • So robot needs to represent the emotions and intelligence in many ways.

  • We have totally different cultures between (the) United States and Japan, right? But I know that we understand (the) emotional expression.

  • There is no doubt emotional facial expressions is a very important way of communication.

  • So therefore, the facial expression is very important for android and for having the communication with human.

  • Hello, My name is Erica.

  • Meet Erica.

  • I think Erica is the most humanlike android in the world.

  • Erica can have a kind of a natural conversation with the visitors.

  • Maybe the five or ten minutes.

  • We are implementing the, maybe just major the facial expression with Erica.

  • Happy,

  • It's all very exciting

  • Angry.

  • I'm done talking to you, please don't come speak with me again.

  • And it's sad and depressed.

  • (foreign language)

  • So android can have their communications by exchanging the facial expressions even if android doesn't understand the language.

  • There are so many great applications for these robots.

  • Whether it's helping the elderly, guiding tourists or even for entertainment.

  • It's all very exciting.

  • Oh, sorry about that.

  • I got a little carried away.

  • By designing robots to have facial expressions, humans could more easily connect with them and incorporate them into our lives.

  • It's just really interesting because we use our faces to reference many different mental states.

  • By expressing the facial expression, even if we don't understand our language to each other, we can share some information.

  • And because of that facial expressions of emotion are the closest thing we have to a universal language, they allow us to share emotions with each other.

  • They allow us to share the time when we laugh together or cry together.

  • If there's anything out there, they're the single most important vehicle that we have that can bring us all together.

There are a lot of us. All with different cultures, languages, beliefs.
