[Music] for many of us people watching is endlessly fascinating even when we can't hear or don't understand what's being said we can often get the gist of it by simply looking our bodies are constantly communicating we don't need a PowerPoint presentation we don't need a stage we don't need a projector or a screen we can display what we really feel at any moment at any time anywhere we are [Music] present body language is an innate part of what it means to be alive and it turns out that actions do speak louder than words why else
would we talk with our hands when the person we're speaking to can't even see us what we know is that some emotions are tied very closely to certain body expressions and that that works in both directions because it's hardwired the body doesn't lie you can't fool people unless you're a phenomenal actor and there very few of them I did not have sexual relations with that woman Miss Linsky most people are no better than flipping a coin in judging deception it's not faces it's not by itself it's not gestures by itself it's not a certain word
by itself it's not scratching my nose or covering my mouth or being fidgety understanding nonverbal communication has become a valuable tool in the justice system an essential skill for security teams a Hightech commodity in the world of marketing and even a potential treatment for post-traumatic stress more than ever it's important to know what is our body language really saying this is a place where stories are told not just with words but with images one of the essential skills here is an intimate knowledge of the human face how it's constructed how it works and most importantly
how it moves what I'm doing is I'm bringing life to something that has no life and one of the easiest ways to do that is to bring facial expressions and emotions into the the face as you can see I'm moving the forehead here so when you you're angry it furrows very quickly and it can go up and you're surprised it raises so there are 43 different muscles in the face and with those muscles you can make 10,000 plus Expressions so everybody knows a smile is a smile and a frown is a frown um which makes
it easier to buy but it's also you got to get it right or something seems off just by reading my face you can tell if I'm happy or angry or disgusted these facial expressions are hardwired to our brains and common to every human being on the planet why is that the answer goes back to the very beginnings of humankind [Music] put yourself in the position of a human 100,000 years ago we'd be out there in the wild worrying about who who's going to come and attack us and there were just non-verbal [Music] behaviors the reason
why we had these things in our evolutionary history is because they had value to us in terms of our survival [Music] if we were walking around 100,000 years ago and all of a sudden I see some something that I think is a threat and I went like this and you saw me do that you probably would not start charging over there and so you're getting signal value from what I'm doing without even talking about it without even expressing the words and this is immediate and automatic our faces communicate fear involuntarily take this couple out for
a drive in the country they struck a moose both of them live to tell the Tale But the look of fear etched on the woman's face would be recognized anywhere on the planet her body is reacting this way for specific reasons what that's doing for me is that it allows me to expand my chest I can take in o oxygen because I'm my body is preparing to fight or flee um my eyes get a little larger so I can in increase my visual uh my visual Fields so I can see more things as opposed to
when I'm angry you bring your brows down and you start doing this so you're narrowing and restricting the visual field so that I am starting to Target non-verbal behaviors all emerged in our evolutionary history to help us communicate with each other about these very basic needs and motives related to survival so for example if we were walking around here 100,000 years ago and I happen to pick up something that I thought maybe we would want to have for dinner and I picked that thing up and I put that in my mouth and I just went
G like this and I gave it to you you probably wouldn't need it well what's really interesting about facial expressions of emotion is that the specific spefic muscle configurations on our faces occur for a specific reason the research has shown that wrinkling your nose actually cuts off some of the nasal passages it helps me not ingest all of this stuff together into my body and so there's a function to that for me when I was uh 23 I was approached by the FBI to become a special agent uh how they found me I don't know
Joe novaro spent 25 years as an FBI agent his specialty was reading body language and by the time he retired he'd earned the nickname the Spy catcher I was involved in a program called the behavioral analysis program and we looked at uh human behavior so that we could understand it so that we could interpret it so we could decode it and uh and use it in uh in our investigations Navarro's success at catching criminals is rooted in looking at things that most of us wouldn't think of one of the things that I noticed immediately was
how accurate the feet were and that the feet were actually more accurate often than the face because by social convention you're walking down the street somebody smiles and you smile back but your feet have no such association with social convention you know the right foot or the left foot will will automatically Orient towards where the person wants to go so we'll make facial contact but our feet are not dedicated to that at at all we have a very ancient part of the brain The Reptilian Brain this has to deal with breathing eating basic survival things
on top of that we have this Exquisite system system called the lyic system it evolved to react and to keep us safe and if it sees a threat and it doesn't matter whether it's a lion or a tiger or words it says stop our olymic system is a bit like software running in the background and whether we like it or not it affects the way we move our bodies we certainly saw this with Prince Charles and princess die they would literally eventually deny each other in a way the the easiest way to teach this is
to is to say belly away don't want you to stay when your lyic system is regulating all of this it's in the moment the whole body is transmitting this is a part of our primate past our ancestors were really good at reading people because if they didn't know who his friend or who his foe they would be dead it's as simple as [Music] that Dr Lillian glass is taking a stroll on the Santa Monica Pier She's a Body Language and Communications expert here to do some people watching the body doesn't lie [Music] you can't fool
people unless you're a phenomenal actor body language can tell you so much she absolutely adores him and you know he's not really giving her much communication he's very much [Music] aloof and you can see she's really cornered him literally she'd like a a lot more than he's giving and she's pulling on a shirt she really wants to get attention they've disconnected she's gone over to the side her head is down and it's not happening and she's she's resigned herself to just look at the ocean there's not a lot of bonding there there's not touching there's
not communication so there's some tension in that relationship when I look at people I look at the whole person I don't just look at one thing one of the things I look for is how close do the couple stand to one another also how are their toes pointed if your toes are pointed in the direction of your partner chances are that you're in good shape they absolutely adore one another it's such a a kind of a beautiful dance to watch this couple they're really connected they're absolutely in sync he kisses her forehead with such love
and affection and tenderness they look right into each other's eyes very very enamored with him and vice [Music] versa how long have you two been together a year a year and has it always been this beautiful and and like a dance yes how did you two meet uh in a company a company you work together yes and you just fell in love I got interested in body language because I started out as a speech pathologist and I was working with people from all walks of life because they thought I look too faminine something from the
bar isn't that amazing please could you get me a double vodka right away the first person I worked with was Dustin Hoffman for the lady oh how about a Duan with a Twist yes ma'am I was the one that taught him how to sound like a woman for Tootsie you're not going to get away with this I got away with it look around and then it kind of grew and started doing a lot of media and wrote 18 books on communication and body language and dealing with toxic people and here I am what I'm doing
is very systematic but you may do it automatically how many times have you said n I don't like that person or you turn on the television ah they're lying I can't stand them I would build a great wall and nobody builds walls better than me believe me Donald Trump whether you love him or you hate him the bottom line is he is a great communicator are you running are you not running his body Lang he doesn't care he makes facial expressions but he's real what is our country coming to and that's what's coming across there's
not phoniness that we've seen so much in our politicians where where they're gesturing like this Trump gestures like this I will be the greatest jobs president that God ever created I trust my guts I trust my instincts and that emotion tells you uh-uh that's not right ah he's full of it oh he's telling the truth so that emotion tells you and that's called your gut level [Music] communication while our instincts help us interpret other people's body language what we do with our own bodies can often happen for reasons beyond our control once you have a
thought before it gets to the voice box it has to go through the area of the brain that controls my hands and this is neurologically true for everybody once I'm going to verbalize a thought it makes me move my hands so doing this is not just a communicative value it's not just having signal value to you who's who are watching this it's helping me think the fact of the matter is our gestures are not just communicative because when you're on the phone and I'm on the phone we're also gesturing even though we know that the
person can't see [Music] us that's the way we are created the body just expresses or embodies what's going on in our minds so how can we decode the body language of other people people in a more systemic way the most obvious place to begin is the face the body doesn't lie and neither does the face because the face is connected with a lot of facial nerves and 12 cranial nerves and when you have an emotion these nerves fire and muscles start moving the resaurus muscle you either smile or you're frowning the master muscles if you're
angry something happens here in your jaw but once it's triggered something in my mind says okay I'm emotional our brains tell us to fire a package of components one set of components has to do with our physiology one set of components has to do with our cognitions and one set of components has to do with our expressive behavior in our hands and our face and all that so that one that goes along that one facial nerve that that lights up our faces in the past 40 years all of the movements our face muscles can make
have been meticulously studied analyzed and codified it's a system known as fax well fax is the acronym for the facial action coding system it breaks down every functional anatomical movement that the face can can make and it codifies each muscle movement by a certain number so whenever a person is moving their face for whatever reason a trained Observer can learn how to identify which muscle is creating that appearance change let's say I there's an expression of fear that occurs I could break down this prototypic expression of fear as in fact Cod would be a one
a two a four five 7 20 with 26 researchers have identified seven universally recognized facial expressions there's joy surprise contempt sadness anger disgust and finally fear for your legs Professor Matsumoto has a black belt in Judo his passion for the sport took him to the 2004 Olympic Games in Athens there he conducted an experiment photographing the faces of the Judo competitors so here are some examples of images that we selected for analysis we then code the muscle movements in the face using the facial action coding system we know of course when the person has won
there's a very large expression of joy that happiness the happiness expression has the muscle around the eye that's inovated it Puffs out the cheeks it gives a little shine it's exactly the same muscles that are inovated right here the prototypic expression of Joy so we did the same kind of study with the par Olympic games that happened in athl 2 weeks after the cited Olympics the blind athletes did exactly the same kinds of facial expressions that cited athletes did now why why is this important it's important because most of these blind athletes were blind from
birth there's no way they could possibly have learned to produce these Expressions by seeing anybody else that means that that the only rational explanation is that we are all born with the ability to produce these Expressions it's an innate ability of ours so here we are a hotel lobby it's a great place to uh people watch here we have uh three women and and we notice you know how often they they either touch each other or signal to each other and this is tells us they've known each other for a while now one of the
ways that we can tell when people are um are standing and talking is uh how relaxed they are and we notice that the the woman just crossed her leg one in front of the other and this is a high Comfort display we only do that when we're comfortable uh around uh um other people we know that this family gets along really well we know this just from the amount of tactile activity we're observing that there's a lot of touching between the the father and uh and the son and this is always a good indicator of
a of a positive relationship and so we see the the young lady fixing the other girls hair and we think of it as this is merely for aesthetic purposes that's only part of it by grooming other people it stimulates the hair follicles and it sends signals to the brain that add to uh psychological Comfort instinctively we can usually tell if people are comfortable with each other but the fact is that many of us will sometimes try to disguise the emotion we are EXP experiencing we do it when we're trying to be polite or we could
be trying to deceive someone detecting deception is where an investigator's expertise comes in handy there is no Pinocchio effect there's not one single Behavior indicative of deception the Paradigm that I like to use is comfort and discomfort that humans are very binary we are either crying as a baby or we're uh quite uh quite satisfied people are either very comfortable or they're struggling with something if you're not an expert on body language it's a good place to at least begin you will see everything from lip biting squinting lip compression furrowing of the forehead displacement of
the jaw they might go we might do a cleansing Behavior where we wipe our hands on our on our legs if we're really stressed you often see people uh pull their socks up and they're literally ventilating uh their skin uh down by the feet they may actually um dimple their cheeks they put pressure on on themselves or they may ring their hands they literally ring their hands the person may run his fingers through his hair or women do it back [Music] here even a light touching of the neck is suggestive that something's wrong we humans
do that a lot um there may be covering of the super sternal notch we go oh my God that happened so we look at all these behaviors and say okay I asked a question and this is their reaction now the question is why why are they behaving like this discomfort can also trigger our face muscles to move in ways that are difficult to spot and even harder to control they're known as micro Expressions micro expressions are quick extremely quick fleeting facial expressions of emotion they happen when you're emotional but you're in a situation where you're
trying to control your Expressions if you can imagine there's a neural tug OFW that's fighting for control over your face the concept of micro Expressions uh started with Darwin in the book the expression of emotion in man and animals basically Darwin stated that sometimes we are so overwhelmed with emotion that despite our best attempts to control them they leak out let's say for example somebody walks in the room and you can't stand them but you're going to smile at them anyway because it's your boss so you go hi you automatically have that snarl but you
don't see that snarl it happens really fast so the micro expressions are the leakage that's occurring because of this neurot of war in situations where I'm an emotional I'm emotional but I'm trying to hide it my Miami International Airport is one of the busiest in the United States every year some 45 million passengers come and go Travelers and their luggage are screened in a variety of ways but an airport is a place where you can be sure your body language is being watched today the woman in charge of airport Public Safety and Security is walking
the terminal first of all we have to know what are our threats and then what are the behaviors associated with those threats these are your bags excuse me who the the bags over here just got to stay with me those are yours so you said the behavior of an individual dropping a bag and walking away from it should raise a red flag behavior is more than just how a person acts it's about their facial Expressions their body language and it's something that we have to intuitively be able to evaluate in a split second here we
actively scan the public looking for something that is just not right how they're dressed how they're acting are they engaged are they disengaged are they zoned out are they wanting to avoid any kind of contact with other people are they trying not to be noticed 10 years ago Stover had a radical idea what if everyone who worked at the airport no matter what job they did was trained in Behavior detection as long as we hire from the human race there will always be threats to deal with and I knew that I had 40,000 troops working
here at this airport that I could use to help me with security and so now all the airport employees check staff mechanics baggage handlers everyone gets training in Behavior detection starting with the janitorial staff a lot of behavior detection is intuitive and we're just using the basic intuition in all of us to just kind of tweak it refine it and give the employees that tool to be able to use it as they assist the passengers you know we have a brown uniform you may have a blue uniform the fact is that our mission is very
similar in sessions like this one Miami Airport workers receive basic training and behavior recognition you guys are most important Assets in the war against not only terrorism but criminal activity um the airport workers are instructed to observe people in the terminal to look out for anything outside the range of normal behavior is anyone loitering is anyone making hand signals do passengers look especially nervous as you know we have to get get it right every day cuz the terrorists only need one shot Miami International also uses more conventional methods there's thousands of cameras here at Miami
International Airport that's the marriage between Behavior detection and Technology what's interesting is their clothing and choice of clothing somebody's going to go to the Bahamas they're not going to be wearing bulky clothing we can look for a person's hands their hand movement is very important we have to try to keep an eye on everybody's hands we don't have the large can9 teeth that other Predators have and so we focus on the hands we look for the hands to say are they welcoming or are they aggressive the two suicide bombers in Brussels with the glove on
their hands that should have stood out as as an anomaly okay okay I go airports typically try to stop passengers from taking dangerous items onto airplanes the focus here is different to stop potentially dangerous people from getting onto planes it's not as much about technology as it is about social psychology developing and sharing the ability to read people when I started in law enforcement there was mostly anecdotal information if you touch your nose you're lying if you touch your mouth you're lying well you know that's just sheer nonsense most people are no better than flipping
a coin in judging deception when people are doing the Shifty eyes thing uh whether their eyes up into the left or down into the right or whatever that is they're lying that's a big myth here at the University of British Columbia there's a small research group focused on deception and Body Language through Evolution it appears that there's been an arms race between reading other people and other people controlling what they want us to see that's the first time you told a lie all day the research is led by forensic psychologist Dr Steven Porter his team
studies the way people interact and the different ways we try to deceive each other Liars or insincere individuals are expected to fidget a lot uh they're expected to look very nervous maybe shift around in their seat and scientifically the real ts are the opposite of that I want you to listen to me I'm going to say this again so if you watch Bill Clinton for example in his denial of having sex with Miss Lewinsky he's burning holes through people in the audience he's he's picking particular individuals and he's just staring them down I did not
have sexual relations with that woman if we look at his non-verbal Behavior as well as his verbal behavior during that claim he comes across as extremely convincing as extremely sincere I never told anybody to lie whether he's a trained liar we don't know but he's certainly he's certainly a very skilled liar not a single time never he conveys anger and hostility at at the idea that anybody was thinking he was even lying these allegations are false he's using this thing we call an illustrator very very effectively and I need to go back to work for
the American people it's an intimidation tactic it's a power and control thing and it's an attention grabber thank you human beings lie to one another on average one to two times per day if you have a pair of human strangers who interact within 10 minutes they're lying to each other on average three times and so we see deception you know in everyday life Little White Lies all the way up to or high stakes lies but it's a really fundamental aspect of social interaction so our research group decided to undertake the largest scale study of high
stakes deception ever conducted and that entailed collecting videos from all over the world of people pleading for the return of a missing relative so in 2008 Carissa budro in Nova Scotia went missing and her mother Penny Buro gave an impassioned plea to the public to try to assist in finding her missing daughter so uh please determine if the individual in the following video is being on the Buro video is used to teach some fundamentals about body language I'll leave the room throughout your discussion and please let me know when you're finished and I will return
and hear your verdict your grandparents are looking for you all of us are I don't know where you are but just come home or call or something please all your friends are looking for you and we're all worried we just want your home safe thank you for coming today good luck she looked distressed clearly yeah she was crying a lot were they real tears of course they were they were they she wiping them yeah you got a point there she was wiping him right off her voice was cracking yeah very true was really sad exhausted
I don't think you would go on national TV if you were lying like I just don't think you would I don't know where you are but just come on recall or something so the interesting thing about the penny budro video is that she shows a classic sign of emotional deception she's attempting to appear distressed because her daughter is missing but she's not showing an engagement of the distressed muscles which are the corrugators in between the eyes which generally when somebody's distressed they go together and up the deceptive pleaders generally are unable to engage those muscles
and they end up looking more like a deer in the headlights they look surprised I took her for a drive that day just to try to have a heart to heart with her in a place like in a car she can't get away and slam her door which she usually does to me in this Frame and a couple frames uh after it Penny dis displays hostility both in her facial expression and in the word she uses and her tone of voice indicating that she's still very upset angry with Carissa for one reason or another she
doesn't want the world to know that she's feeling that but it's coming out involuntarily can I ask you what this has been like as a mother Penny responds to the question from the interviewer with a flash of anger and hostility she knows that her daughter is dead the interviewer is asking questions that are getting a little too close to home Porter shared his team's insights with police investigators the police then switched the focus of their investigation to Penny budro herself eventually they got information that she had in fact murdered her daughter because her boyfriend the
suspect had mentioned one day he didn't think he was ready to be a father thank you one thing that I've learned that that really surprised me was the extent the magnitude of information that we're conveying any moment uh via our body language our facial expressions and what we're saying even Psychopathic liar who are you know some of the best around us aren't able to control quote unquote leakage via at least one of these different communication channels it's not just the human face that reveal inner thoughts you can tell a lot about a person from the
way they walk imagine we are in the savannah in Africa as early man was and they're looking on the horizon and they see people walking what's their gate cuz that's really what they can see are they walking towards us away from us are they walking aggressively The Way We Walk can say a lot it can reveal our intentions our state of mind and our physical health at Queens University in Canada they are studying biological motion the research is led by Dr Nicholas tro he's interested in how the human brain instinctively interprets the way people move
people spend a lot of time watching other people and we've become experts in it when we talk about body language it's a signal which is in a way much more honest than facial expression because it's much harder to fake and it's much harder to control the humans apparently are very very efficient in decoding the information which is contained in the way humans move if you feel something is odd or if you feel uncomfortable with someone um who is moving a system kicks in that no if something is not quite right what I'm showing you here
is uh 15 dots on the screen and you might be able to make out a um human behind those dots but that changes dramatically if I set it into motion so if this one moves you can't help but um seeing a person here um you see more than just a person you can determine whether or you can at least make a good guess whether this here is a male so you see hear this lateral body Sway and you see the shape of the male changing a little bit with wider shoulders and narrower hips on the
other hand here you see this clearly a woman here um with a very different movement so more uh vertical movement here less lateral body's way more moving in the hips here you can see more than the than the gender of the Walker I can make it more um um relaxed here um we can make the woman a little more um happy here you see that vertical bounciness and the swing and the um in in the motion here I've always been fascinated by how much information apparently there is in the way people um appear and what
fascinates me most is really the sophistication of the information that we can retrieve from it the human visual system does it without thinking we just do it so obviously the way we feel affect the way we pose our body and also the way we move but interestingly um the way we move can also have effects on the way um we feel so we're really fascinated with body language and we're particularly interested in other people's body language you know we're this is one of the most watched TED talks of all time with more than 36 million
online views the speaker is American social psychologist Amy C Jud us and what the outcomes are we tend to forget though the other audience that's influenced by our nonverbals and that's ourselves cuy is on the teaching staff at the Harvard Business School she's renowned for her work on so-called power poses the idea that we can actually make ourselves feel more powerful simply by the way we carry ourselves your body and your mind are constant stantly in conversation with each other and your body is largely driving that conversation why not take control of that why not
have your body tell your mind that you're safe and Powerful rather than having your body tell your mind you're not safe you're not powerful so if you take non-human primates I mean you see them expand their chest uh pound their chest they do things to make themselves appear bigger than the other individuals in their hierarchy you see this kind of body language across the animal kingdom and similarly when animals feel powerless they do exactly the opposite they make themselves tiny humans are animals as well and we do the same kinds of things some of the
most expressive examples of body language happen in the world of dance in the classical ballets the female lead character is usually either dead or half dead she's fragile frail and by the end she's all you know withered up on the floor like the dying swan in more contemporary ballet you see a lot more expansiveness in the female lead characters so think of Alvin Dance Theater where so many of the ballets are about Liberation and freedom and power I think it's a really dangerous message that we send to our daughters that femininity is tied to being
fragile and frail and and you know wrapping oneself up [Applause] the Haka is a really powerful dance that's performed by the New Zealand national rugby team called the All Blacks they'll be facing the other team and going through this series of really powerful postures it's kind of beautiful and intimidating at the same time important thing to understand about the Haka is that it's really not primarily about intimidating the other side it is primarily about preparing themselves for a challenging situation do we have those displays in other cultures well we do in a sense when a
president uh or the head of state arrives and they review the troops that is a stationary haaka the troops are usually very tall very resplendant in their uniform and we look at them and we inspect them and we say okay you guys look pretty tough at Essence they are really a displays of who we are what we are and what we can do and what's fascinating is it's all nonverbal 31st International between New Zealand All of Us display non-verbal Communication in our daily lives and our bodies often reveal to others how we feel when we
walk and we're sad we walk in this slouched way and when we walk and we're happy we're walking in a more erect posture and we're you know swinging our arms more you our stride is longer so getting people to walk in a happy way makes them feel happy even if they have no idea what they're doing this is a really new area of research that some people call embodiment and I don't think we know exactly what the mechanism is I think what we know is that some emotions are tied very closely to certain body expressions
and that that works in both directions because it's hardwired where's it at I think some of the most promising applications of this work and we're just at the beginning of this now um but are in the area of treating people with uh things like post-traumatic stress come on post-traumatic stress is the most extreme form of powerlessness where we at where we at where people feel that their bodies in some way betrayed them by not getting them out of an unsafe situation they really carry trauma in their bodies heads up they're shooting the law combat veterans
with post-traumatic stress in particular are maybe less like liky to want to talk about uh their situation and so these body based therapies are proving to be really effective red smokes out teaching people to sit upright and open their chests and breathe more deeply is in fact calming the nervous system it is communicating with through the Vagas nerve um with the mind right it's it's telling the Vegas nerve that that you're not in a fight ORF flight situation you're in a rest and digest situation that you are safe I'm really hopeful that we're going to
learn more about how to use body-based interventions to treat psychological disorders and people can do these things so easily they can change their breathing so easily that it's really proving to be quite [Music] effective in the heart of Amsterdam you'll find the Nemo Science Center one of the displays is designed to help children learn about the meaning behind different facial expressions they learned that facial expressions are Universal and are common to all cultures Roberto Valente and his colleagues helped to design the science center display their company is working on a special project with the University
of Amsterdam we're teaching computers to understand the body language of humans valente's company promises fast accurate analysis of facial expressions the analysis is done by using imaging software and computer algorithms so here when I deform am out and erase my uh uh corners of the mouth you will have an eff expression if I wrinkle my nose you would have discussed the focus of sorp is mainly on recognizing the signals that come from your face and of course you can use this signal for many different application and you can see currently the application is all about
market research specifically how to measure a consumer's reaction to an advertisement positive or negative imagine that you can Target your advertisement depending on who is in front of it that's a very uh interesting return of investment for The Advertiser and now we can really fine-tune the the the what ad is being displayed depending on the target group what this means is that not only a we looking at the ad the ad is looking at us and the ad can adjust itself depending on who's looking this is a demonstration of a narrow casting application which will
be targeting advertisement to the group of people that are in front of the advertisement screen and you can see here now we have a majority of of of male uh in the in the C camera when the mail get out of the picture we can see that the commercial switches to a female advertisement and uh and we can go back in it switches back to a male advertisement the computer needs to understand the human in order to be able to uh deliver to the human so not only understand the human on in terms of um
you know voice recognition but also gestures and and facial expressions the first one we can also apply this into direct human computer interaction but human robot interaction for instance uh um uh a robot will be able to understand the body language the sensitive spots so to really establish a a much more natural form of communication so far computers have not really tapped in this kind of information and when computer can learn like a human and can interact to human like a human I think that's where the interesting consequences and Promises of human computer interaction can
appear left or I'm looking right U I'm really excited about the the developing Technologies but I also believe that the old-fashioned observation human observational approach is is a critical comp component that being able to closely observe holistically you have an advantage that machines never will but there's no stopping the machines we see them more and more in our daily lives fingerprint scanners Palm printing an iris recognition software it's all becoming routine and while gate recognition is not yet a reality it's surely coming I think that we've just scratched the surface for understanding the complexity of
our bodies and all of the expressive channels that we have whether it's face hands posture gate and we are getting some glimpses of how important it is and how interesting it is but how complex it is it's interesting once you explain things or you begin to talk to people about body language or they say oh you know that's just uh common sense and then when you say well how often in the past did you notice uh neck touching or ventilating or you know the pinching of the corner of the mouth to show contempt people really
reveal themselves when you stop and look and decipher what's really going on and we don't do that [Music] enough I've learn that nonverbals are more accurate than the spoken word that's true but I think my family would tell you it's there is a burden when you can read people with exactitude you see things even before they see them you see marriages falling apart months in advance that's hard why are we doing this and I think it behooves every scientist to have an answer I think the ultimate goal of a better understanding of of human behavior
is the Improvement and betterment of society for for the ages the reason why I'm I'm going to be watching these videos for the next 5 years of these studies that we've got is so that we can give that information to others so that somebody can improve our society for some reason keep us safer take the criminal off the street or do something that that does us some good the day will come when we will have a much deeper um understanding of U of of body [Music] language the question is what will we do with that
[Music] [Music]
