What ever became of "Micro Gestures"?
What ever became of "micro gestures", I mean their study as a sign for the truth or of telling lies in people, when watched closely, they exhibit certain micro gestures (or "micro expressions"), which are signals as to how truthful or decietful the person is being, and it's supposed to work very well, but the micro gestures happen very quickly and are not that easy to notice, at least some, it is done by recording and or analyzing the persons expressions, etc.... (camera and computer...)
I had heard of it on TV shows several years ago, and not since, I think they could have been and still be used to anyone, and that we don't necessarily hear much of it anymore does not mean it is not a valid or useful method.
Perhaps we could discover more signs of some of the liars lying if we applied this technique to things they have said to us?
And there may be something relating to that about why there isn't as much attention on it anymore, too?
Polygraph no match for new lie detecting technique
A new technique developed by scientists at Manchester Metropolitan University that interprets facial gestures could be the most accurate 'lie detector' yet discovered. Using just a laptop and a camera, the method has demonstrated significantly better results than the traditional polygraph lie detectors used by the CIA and is much simpler to use, needing no experts to operate it and no physical contact with the suspect.
The 'Silent Talker' the system uses artificial intelligence to detect and analyse thousands of micro-gestures, many of which go unnoticed by the naked eye. The system reads stress, deception, tiredness and other traits to analyse non-verbal behaviour, which makes up 93% of all human communication. Tiny involuntary movements that are considered impossible to fake are detected by Silent Talker, which then analyses incongruities to identify when someone is lying. Project director Dr Zuhair Bandar in the University's Department of Computing and Mathematics said: "We have looked at systems across the world and are convinced that this is the most sophisticated".
"A breakthrough in the UK is all the more significant given the large budgets made available for security in the USA post September 11.
"In phased tests to date, the system is accurate in over 80% of cases, compared to 70% for the best other current systems.In one test, researchers asked volunteers to steal '10 each from a box and asked them to deny knowledge of the theft when later questioned. To compare the different reactions, another group who had seen but not stolen the money, was also quizzed about the missing money. During questioning, a secret camera filmed the interviewees faces. It correctly identified the liars in 80% of cases.Banks and insurance companies have already expressed interest in the system, which has manifold applications from job interviews and police investigations to airport security and counter-terrorism. It also has applications in medicine and could aid the diagnosis and monitoring of depressions, schizophrenia and psychopathy. The team is currently working with psychologists from MMU and the Universityof Liverpool, and has secured a patent application for its system.

Truth machine means liars must keep a straight face
There are lies, damned lies and imperceptible micro-gestures. Scientists in Manchester are claim they can now detect them with the world's most sophisticated lie-detector.
There are lies, damned lies and imperceptible micro-gestures. Scientists in Manchester are claim they can now detect them with the world's most sophisticated lie-detector.
Using only a laptop computer and a camera, the truth machine condemns the deceitful by spottingmuscle twitches.
A team at Manchester Metropolitan University spent five years developing the device, which detects and analyses thousands of tiny facial movements, many imperceptible to the naked eye. The scientists say it has the potential to screen for hijackers and insurance cheats with unprecedented accuracy.
They claim that tests demonstrated an 80 per cent accuracy rate – against 60 per cent for the traditional polygraph lie detector, which monitors signs of stress such as perspiration, heart rate and voice pitch.
The device, which is being called "Silent Talker", is also much simpler to use and it delivers degrees of lying – complete lie and half-lie.
Dr Zuhair Bandar, the project director, said: "They interviewed the Yorkshire Ripper at least five times [before he was caught]. I am convinced that this is the kind of device which would have told them something was wrong."
Lie detector tests and polygraph tests.
Lie detector testing from distress services
US tests $3.5m computerised lie detector
The US Department of Homeland Security has earmarked $3.5m to help scientists develop next-generation computer-based lie detectors.
The funds will be awarded to computer scientists at Rutgers, The State University of New Jersey, who are already researching how subtle body movements, such as shoulder shrugging, hand gestures or slight changes in facial expression, may indicate deception.
The goal is to capture these non-verbal cues on camera, have a computer analyse them and deliver immediate input on the subject's likely truthfulness.
Researchers foresee their techniques helping immigration officers screen people more quickly and accurately at border crossings and ports of entry into the US. The techniques could also bolster security for buildings such as embassies, and help law enforcement personnel in routine interrogations.
"Looking for what we call 'micro-expressions' and 'micro-gestures' associated with deception would be a major leap over today's polygraph technology, which is time consuming and requires professional administration," said Dimitris Metaxas, computer science professor and director of the university's Center for Computational Biomedicine Imaging and Modeling.
"Even under the most controlled conditions, lie detector tests based on body physiology are roughly 50 per cent reliable. But we believe gestures and expressions are a lot harder for someone to mask, and do not vary significantly among races and cultures.
"Micro-expressions may easily escape notice by human observers, but can be reliably picked up on camera and quickly detected by computer, giving interrogators new tools to do their jobs confidently."
Metaxas explained that he is building on his earlier research into the computer modelling of facial expressions and the dynamics of body organs, such as a beating heart or blood flowing through vessels.
This work employs image-based models that enable computers realistically to simulate subtle yet detailed muscular movements, such as those that make up facial expressions.
However, the scientists pointed out that "several challenges remain" including accurately correlating facial expressions to deceptive intent and verifying how consistently these occur across cultures.
Another problem centres on the incorporation of new cues, such as gestures and body postures, into the computer models.
The researchers will also study how accurately they can capture movements under 'real world' conditions of varied lighting, background motion and potential distractions such as people wearing glasses and men with facial hair.
While Metaxas will conduct early studies with multiple cameras, his goal is to make the recognition and analysis procedures robust enough to work with a single camera.
In addition to using cameras to capture images, the team will employ 3D sensor technology to capture the range of body movements. Rutgers is collaborating with Lockheed Martin on 3D sensor development and integration.
Police consider lie detector tests
Police in the North West could soon use lie detection tests to interrogate suspects.
The test is said to be more accurate than the polygraph
Researchers are in talks with forces in the region to test the technology - the first time it would be available for forces in the UK.
The new system looks for involuntary gestures which act as clues as to whether the person being interviewed is telling the truth.
The Silent Talker device has been developed in the region and is touted as having a 90% success rate.
It uses a video camera linked to an artificial intelligence system that spots small movements people make unconsciously when they lie.
The traditional polygraph test, used in the US, is claimed by some to have a 60% to 70% success rate.
But Mark Littlewood, of the human rights organisation Liberty, said the device could infringe people's rights.
He added: "The full consent of the suspect should be required.
"We are sceptical of its reliability and believe its more widespread use would be a serious and unacceptable erosion of the right to silence."
Ian Donald, a psychology professor at Liverpool University, told The Engineer magazine that a great deal of interest had been shown in the project.
He said developers were in informal talks with Cheshire, Greater Manchester and Merseyside police forces.
Dr Janet Rothwell, psychology researcher at Manchester Metropolitan University, said: "The artificial intelligence system watches for micro-gestures, blushing and head and shoulder movement.
"At a basic level it is trained to identify an object, such as an eye.
"The next level is to understand if that object is being deformed, for example an eye changing shape."
Suspects and their lawyers could still veto the use of the technology during interviews and the law would need to be changed before results could be admissible in court.
The Police Information and Technology Organisation said it was monitoring the project.
The US government is also believed to be interested in Silent Talker, said The Engineer.

‘You can tell when politicians are lying’ so the cynical adage goes ‘ because
their mouths move’
The truth about lying
By: John Boe
Some people can't tell a lie, others can't tell the truth and, unfortunately, most people can't tell the difference. Can you tell when someone is pulling the wool over your eyes? Whether you're an attorney selecting a jury, a manager interviewing a new agent or a salesperson making a presentation, your ability to quickly and accurately discern the truth greatly enhances your effectiveness.
Fortunately, having the ability to sort fact from fiction is an important communication skill that can be learned.
Aside from con men, compulsive liars and some politicians, most people become uncomfortable when telling a lie and transmit their deceitful behavior through their body language. While they may sound convincing, their gestures speak louder than their words. Consequently, they reveal their deceit nonverbally. While it's not always easy to spot deceptive behavior, there are many subtle yet discernable clues to the trained eye.
Body language is a mixture of movement, posture and tone of voice. Studies show that nonverbal communication has a much greater impact and reliability than the spoken word. Therefore, if a person's words are incongruent with his or her body language gestures, you would be wise to rely on the body language as a more accurate reflection of their true feelings.
During the selling process it's important to remember that body language is not a one-way street. While you're evaluating your prospect's body language for signs of honesty and credibility, he or she is subconsciously observing and reacting to your gestures as well.
Truth sometimes hurts
The truth sometimes hurts and few business or personal relationships could survive the harsh reality of total honesty. While honesty is certainly the best policy, the truth is, that in our day-to-day encounters, it's not always diplomatic or socially acceptable to be completely honest. To spare the feelings of others, we have learned the usefulness of telling half-truths, fibs and white lies.
During the selling process, some people have difficulty saying “no” and will actually tell you that they are interested in order to avoid potential conflict. As the pressure of making a decision builds, prospects will frequently use half-truths or lies to either stall or disengage from the selling sequence. While their words say “yes,” their body language indicates “no.” By being able to recognise the inconsistency between your prospect's words and his or her gestures, it is often possible to flush out their concerns, overcome their objections and make the sale.
Three wise monkeys
Eye, nose and mouth movement, along with hand gestures, are the four major nonverbal cues typically associated with lying. The statue of the Three Wise Monkeys accurately depicts the primary hand-to-face gestures associated with deceit. When a person is doubtful or lying, they'll often use their fingers to block their mouth as if they were filtering their words. This hand-to-mouth gesture is commonly referred to as “speak no evil.” The second hand gesture associated with deceit is called “see no evil,” and it occurs when a person rubs or touches his or her eye(s). The third hand gesture “hear no evil” is displayed when a person covers or drills a finger into his or her ear(s).
If people use one of these gestures while they're talking, it indicates that they are being deceitful. Alternatively, if they are displaying one of these gestures while someone else is talking, it indicates that they doubt the truthfulness of what is being said. These three gestures should be considered red flags.
When you encounter one of these gestures during your presentation, it is a good idea to gently probe the subject matter with open-ended questions to encourage your prospect to voice his or her concern.
In addition to the three hand-to-face gestures, eye movement is another reliable indication of deceit. It's normal for a person to look up to his or her left when thinking about the past and up to the right when thinking about the future. If you ask a person a question from his or her past and they look up to their right, they're making up a response. Law enforcement personnel and customs agents are trained to routinely monitor eye movement during interviews.
According to Paul Ekman, professor of psychology at the University of California, San Francisco, two of the most common micro gestures that are associated with deceit are the nose wrinkle and the mouth curl. The nose wrinkle is the same gesture that occurs naturally when you smell something offensive. The other facial micro gesture is a slight downward curl of the corners of the mouth. Even liars who make a conscious effort to suppress all of their major body gestures, will still transmit micro gestures.
People sometimes lie, but their body language always tells the truth!
There are some people who can’t tell a lie, many who can’t tell the truth, and unfortunately, most people can’t tell the difference. Can you tell when someone is pulling the wool over your eyes? As children, we were raised to tell the truth and taught that honesty is always the best policy. We were told stories about George Washington and Honest Abe Lincoln to reinforce the virtue of truthfulness. However, as we grew older, we realized that the truth sometimes hurts and that few relationships could survive the harsh reality of brutal honesty. To keep from hurting others, we learned the usefulness of telling “white lies.” On the other hand, self-serving lies can be damaging and are frequently used for personal gain or to avoid punishment.
Scientists looking for a reliable way to expose liars invented the polygraph machine, also known as the lie detector, in the 1920’s. While certainly not a perfect machine, it is estimated that the lie detector has a ninety percent accuracy rate. While polygraph evidence is not permitted in a courtroom, the CIA, FBI, police, and employers routinely use it as an interviewing tool. In addition to using a lie detector, many law enforcement agencies videotape interviews in order to evaluate body language gestures in detail. Gestures or expressions that occur in less than one second are called micro gestures. Micro gestures are extremely difficult to observe unless they have been recorded on videotape and played back in slow motion. Body language experts have identified and categorized thousands of human gestures and their associated meanings. It might surprise you to know that research indicates over 65% of our communication is done nonverbally. In fact, studies show that nonverbal communication has a much greater impact and reliability than the spoken word.
Body language is a complex mixture of movement, posture, and tone of voice. Developing a working understanding of body language is similar to learning a foreign language in that it requires time and effort to achieve mastery. Typically, when someone is lying, they subdue their gestures and avoid direct eye contact, or have what is termed, “shifty eyes.” The three primary facial gestures associated with lying are called; “speak no evil, see no evil, and hear no evil.” The “speak no evil” gesture is when someone filters their words through their fingers or uses their hand to block their words. The gesture “see no evil” occurs when an individual rubs their eye(s) while they are talking. The third facial gesture, “hear no evil”, occurs when a person covers their ear(s) or drills their finger into their ear as they are speaking. The two, less obvious lying gestures are micro gestures, which require close observation to detect. The first of these subtle, but important micro gestures is a nose wrinkle. This is the same gesture that occurs naturally when you smell something offensive. The other facial micro gesture that is used to detect lying is a slight downward curl of the corners of the mouth. People sometimes lie, but their body language always tells the truth!
To a degree, one can learn to read body language accurately. The
trouble is, it only works *generally.* There will always be people who
can lie without giving off body language that indicates they are
lying, and there will always be people who may seem to be lying, but
On the other hand, watching someone on video tape may give you an
advantage. There's a reason law enforcement officials often tape
interviews. They slow the tapes down later, and look for Micro
Gestures, which last a mere second and are difficult to catch
(Video links above)
I think we should apply this technique or method to the statements and speeches that the lying politicians have said to us, to their recordings and so on, that this could be applied to, of couse they know about it, too, and do their best to suppress any indications of lying, that is why Bush always tries to be so very straight faced in any speech or press conference.......
So, does anyone else think anything of this as a possibly useful
tool to include for revealing the truth behind their lies, so to speak?
