The AI that can train your dog: Researchers develop smart harness that respond to your dog's body language
Smart harnesses have a small computer roughly the size of a deck of cards
They also contain array of sensors to monitor posture and body language
When proper behaviour is detected, algorithm triggers release of a treat
Researchers have developed a computer system that can train dogs without the help of a human.
The team from North Carolina State University developed a harness which contains an array of sensors to monitor posture and body language.
Using a small built-in computer to transmit data, the system can give out rewards for correct behaviour by releasing a treat from a nearby dispenser.

The team from North Carolina State University developed a harness which contains an array of sensors to monitor posture and body language. Using a small built-in computer to transmit data, the system can give out rewards for correct behaviour by releasing a treat from a nearby dispenser
HOW IT WORKS
Researchers from North Carolina State University developed a harness which contains an array of sensors to monitor posture and body language.
Each harness also has a small computer, roughly the size of a deck of cards.
The tiny computer transmits data from the sensors wirelessly, and when the proper behaviour is detected, the algorithm triggers a 'beep' and releases a treat from a dispenser nearby.
While the algorithm proved to be highly accurate, rewarding the correct behaviour 96 percent of the time, the human trainer still performed better, with an accuracy rate of 100 percent.
But, the algorithm was consistent in its response time, while the times of the human trainer varied.
Researchers say consistency is a critical component of training.
Each harness has a small computer, roughly the size of a deck of cards.
This works in conjunction with the harness's built-in sensors and a custom algorithm that triggers the rewards.
In order to fine-tune the algorithm to optimize speed and accuracy, the researchers worked with 16 volunteers and their dogs, comparing the performance of the algorithm with the timing and accuracy of a human trainer.
'Our approach can be used to train dogs efficiently and effectively,' says David Roberts, an assistant professor of computer science at NC State and co-author of a paper on the study.
'We use sensors in custom dog harnesses to monitor a dog's posture, and the computer reinforces the correct behaviour quickly and with near-perfect consistency.'
Researchers had the system reward dogs for correctly moving from a standing to sitting position.

Is Your Body Language Holding You Back at Work?
Have you ever been too intimidated to speak up in a meeting, felt self-conscious at a networking event, or were a bundle of nerves during a job interview? Most of us have experienced a lack of self-confidence at one time or another, and some may even feel that way in everyday life. But what if you could create more confidence just by changing your body language… and even feel more powerful? A social psychologist from Harvard studied this very subject, and she believes you can — just by making a few small tweaks.
In her TED Talk, How Your Body Language Shapes Who You Are, social psychologist Amy Cuddy discussed how our body language sends certain messages about us, and how by changing some of our postures and gestures we may be able to change the way those messages are perceived in a positive way.
Stop making yourself small
SmallWhen people are feeling nervous or lacking confidence, they have a tendency to hunch, cross their arms, or just fold into themselves, making them look (and feel) smaller. According to Cuddy, women are even more likely than men to use these “low-power poses,” as women often feel inherently less powerful than men. But by making yourself smaller and taking up less space around you, you’re communicating that lack of confidence to others, which can make managers and colleagues less likely to hear out your ideas or depend on you for important tasks — which could eventually translate into being passed over for promotions.
If you’re job hunting, you could also be hurting your chances of getting the gig when you display this type of body language. Through their research, Cuddy’s team found that hiring managers were more likely to select candidates who displayed more “powerful” body language.
Nail the “high-power poses”
bigYou know that person who comes into the conference room with their head held high, waving at everyone as they enter, and then sits down and props their arm up on the empty chair next to them? That person is displaying high-power body language. According to Cuddy, this is a nonverbal expression of power and dominance. In the wild, when animals want to show dominance, they make themselves bigger by opening up and occupying space. Even smaller animals can be dominant, like when a chihuahua becomes the alpha dog in a home with a boxer and a pit bull. The same is true for humans; it’s not about physically being a bigger person, it’s about having a bigger presence.
By displaying high-power poses at work, people are more likely to see you as a confident and competent person, and as someone who could be a capable leader. This opens up more opportunities for advancement or promotion, and provides you with an edge if you’re interviewing for a new position or looking to make a career change.
Hormonal effects
It’s not just those around us that are influenced by our nonverbal cues. The different types of body language we use actually create chemical changes in our bodies, which can affect the way we feel and act. Cuddy’s team tested the testosterone and cortisol levels of people after spending 2 minutes in a high- or low-power pose. What they found was that individuals in the high-power pose experienced a 20 percent increase in testosterone and a 25 percent decrease in cortisol (you know, that stress hormone that drug commercials say gives us belly fat). After 2 minutes in low-power poses, the test subjects averaged a 10 percent decrease in testosterone and a 15 percent increase in cortisol.
Fake it ‘til you make it
Even if the high-power poses seem outside your body language comfort zone, you will likely experience hormonal changes similar to the ones in the study just by making yourself do them, which can change how you feel about yourself and give you a confidence boost. As Cuddy put it: “Our bodies change our minds.”
When it comes to power, you can “fake it ‘til you make it.” Even if you aren’t feeling so powerful or confident, you can pretend to be — by making yourself bigger, taking up space, and displaying your dominance. The more often you “fake it,” the more confident and assertive you will become, thanks to that surge in testosterone.
According to Cuddy, powerful people tend to be more optimistic, can think more abstractly, and tend to take more risks. All of which can benefit you in your career, and in life in general. So rather than letting a little nervousness or self-consciousness hold you back or mask the great talents and ideas you have inside, try making these small changes to your body language and see what happens.
BODY LANGUAGE EXPERT SAYS DEPP AND HEARD'S MARRIAGE WAS DOOMED
It would appear the celeb couple's split had been coming for a while.
It came as no surprise to Darren Stanton, the world's leading body language expert, that Johnny Depp and Amber Heard announced they were divorcing.
According to Stanton, the couple's body language in their apology video to Australia showed "hostility" in their relationship.

"I think it's clear at the time of the interview that they are clearly not on the same page in terms of being a couple," Stanton explained to The Telegraph.
"At no time time do they make contact... It's almost like two independent people speaking."

He added: "The words being spoken are so incongruent with the tonality and body language, which is stoic and cardboard. Normally when people are in agreement, their posture will be pointed towards each other."
We guess the writing has been on the wall for a while now.
The couple announced their divorce yesterday after 15 months of marriage.
The Pirates of the Caribbean star's rep has released a statement addressing the marital breakdown.
"Given the brevity of this marriage and the most recent and tragic loss of his mother, Johnny will not respond to any of the salacious false stories, gossip, misinformation and lies about his personal life. Hopefully the dissolution of this short marriage will be resolved quickly."

8 Great Tricks for Reading People's Body Language
Body language provides an amazing amount of information on what other people are thinking if you know what to look for. And who hasn’t wanted to read people’s minds at some point?
You already pick up on more body language cues than you’re consciously aware of. UCLA research has shown that only 7 percent of communication is based on the actual words we say. As for the rest, 38 percent comes from tone of voice and the remaining 55 percent comes from body language. Learning how to become aware of and to interpret that 55 percent can give you a leg up with other people.
When you’re working hard and doing all you can to achieve your goals, anything that can give you an edge is powerful and will streamline your path to success.
TalentSmart has tested more than a million people and found that the upper echelons of top performance are filled with people who are high in emotional intelligence (90 percent of top performers, to be exact). These people know the power that unspoken signals have in communication, and they monitor body language accordingly.

Next time you’re in a meeting (or even on a date or playing with your kids), watch for these cues:
1. Crossed arms and legs signal resistance to your ideas.
Crossed arms and legs are physical barriers that suggest the other person is not open to what you’re saying. Even if they’re smiling and engaged in a pleasant conversation, their body language tells the story. Gerard I. Nierenberg and Henry H. Calero videotaped more than 2,000 negotiations for a book they wrote on reading body language, and not a single one ended in an agreement when one of the parties had their legs crossed while negotiating. Psychologically, crossed legs or arms signal that a person is mentally, emotionally, and physically blocked off from what’s in front of them. It’s not intentional, which is why it’s so revealing.
2. Real smiles crinkle the eyes.
When it comes to smiling, the mouth can lie but the eyes can’t. Genuine smiles reach the eyes, crinkling the skin to create crow’s feet around them. People often smile to hide what they’re really thinking and feeling, so the next time you want to know if someone’s smile is genuine, look for crinkles at the corners of their eyes. If they aren’t there, that smile is hiding something.
3. Copying your body language is a good thing.
Have you ever been in a meeting with someone and noticed that every time you cross or uncross your legs, they do the same? Or perhaps they lean their head the same way as yours when you’re talking? That’s actually a good sign. Mirroring body language is something we do unconsciously when we feel a bond with the other person. It’s a sign that the conversation is going well and that the other party is receptive to your message. This knowledge can be especially useful when you’re negotiating, because it shows you what the other person is really thinking about the deal.
4. Posture tells the story.
Have you ever seen a person walk into a room, and immediately, you have known that they were the one in charge? That effect is largely about body language, and often includes an erect posture, gestures made with the palms facing down, and open and expansive gestures in general. The brain is hardwired to equate power with the amount of space people take up. Standing up straight with your shoulders back is a power position; it appears to maximize the amount of space you fill. Slouching, on the other hand, is the result of collapsing your form; it appears to take up less space and projects less power. Maintaining good posture commands respect and promotes engagement, whether you’re a leader or not.

5. Eyes that lie.
Most of us probably grew up hearing, “Look me in the eye when you talk to me!” Our parents were operating under the assumption that it’s tough to hold someone’s gaze when you’re lying to them, and they were right to an extent. But that’s such common knowledge that people will often deliberately hold eye contact in an attempt to cover up the fact that they’re lying. The problem is that most of them overcompensate and hold eye contact to the point that it feels uncomfortable. On average, Americans hold eye contact for seven to ten seconds, longer when we’re listening than when we’re talking. If you’re talking with someone whose stare is making you squirm -- especially if they’re very still and unblinking -- something is up and they might be lying you.
6. Raised eyebrows signal discomfort.
There are three main emotions that make your eyebrows go up: surprise, worry, and fear. Try raising your eyebrows when you’re having a relaxed casual conversation with a friend. It’s hard to do, isn’t it? If somebody who is talking to you raises their eyebrows and the topic isn’t one that would logically cause surprise, worry, or fear, there is something else going on.
7. Exaggerated nodding signals anxiety about approval.
When you’re telling someone something and they nod excessively, this means that they are worried about what you think of them or that you doubt their ability to follow your instructions.
8. A clenched jaw signals stress.
A clenched jaw, a tightened neck, or a furrowed brow are all signs of stress. Regardless of what the person is saying, these are signs of considerable discomfort. The conversation might be delving into something they’re anxious about, or their mind might be elsewhere and they’re focusing on the thing that’s stressing them out. The key is to watch for that mismatch between what the person says and what their tense body language is telling you.

The bottom line is that even if you can’t read a person’s exact thoughts, you can learn a lot from their body language, and that’s especially true when words and body language don’t match.

8 Ways Body Language Beats IQ
When it comes to success, it’s easy to think that people blessed with brains are inevitably going to leave the rest of us in the dust, but social psychologist Amy Cuddy knows first-hand how attitude can outweigh IQ.
Cuddy suffered a car accident at the age of 19 which resulted in brain damage that took 30 points from her IQ. Before the crash Cuddy had an IQ near genius levels; her post-crash IQ was just average.
As someone who had always built her identity around her intelligence, the significant dip in Cuddy’s IQ left her feeling powerless and unconfident. Despite her brain damage, she slowly made her way through college and even got accepted into the graduate program at Princeton.
Once at Princeton, Cuddy struggled until she discovered that it was her lack of confidence that was holding her back, not her lack of brainpower. This was especially true during difficult conversations, presentations, and other high-pressure, highly important moments.
This discovery led Cuddy, now a Harvard psychologist, to devote her studies to the impact body language has on your confidence, influence, and, ultimately, success. Her biggest findings center on the powerful effects of positive body language. Positive body language includes things like appropriate eye contact, active engagement/listening, and targeted gestures that accentuate the message you’re trying to convey. Studies show that people who use positive body language are more likable, competent, persuasive, and emotionally intelligent.
Here’s how it works:
Positive body language changes your attitude. Cuddy found that consciously adjusting your body language to make it more positive improves your attitude because it has a powerful impact on your hormones.
It increases testosterone. When you think of testosterone, it’s easy to focus on sports and competition, but testosterone’s importance covers much more than athletics. Whether you are a man or a woman, testosterone improves your confidence and causes other people to see you as more trustworthy and positive. Research shows that positive body language increases your testosterone levels by 20%.
It decreases cortisol. Cortisol is a stress hormone that impedes performance and creates negative health effects over the long term. Decreasing cortisol levels minimizes stress and enables you to think more clearly, particularly in difficult and challenging situations. Research shows that positive body language decreases cortisol levels by 25%.
It creates a powerful combination. While a decrease in cortisol or an increase in testosterone is great on its own, the two together are a powerful combination that is typically seen among people in positions of power. This combination creates the confidence and clarity of mind that are ideal for dealing with tight deadlines, tough decisions, and massive volumes of work. People who are naturally high in testosterone and low in cortisol are known to thrive under pressure. Of course, you can use positive body language to make yourself this way even if it doesn’t happen naturally.
It makes you more likeable. In a Tufts University study, subjects watched soundless clips of physicians interacting with their patients. Just by observing the physicians’ body language, subjects were able to guess which physicians ended up getting sued by their patients. Body language is a huge factor in how you’re perceived and can be more important than your tone of voice or even what you say. Learning to use positive body language will make people like you and trust you more.
It conveys competence. In a study conducted at Princeton, researchers found that a one-second clip of candidates for senator or governor was enough for people to accurately predict which candidate was elected. While this may not increase your faith in the voting process, it does show that perception of competence has a strong foundation in body language.
It’s a powerful tool in negotiation (even virtually). There’s no question that body language plays a huge role in your ability to persuade others to your way of thinking. Researchers studying the phenomenon in virtual communication found that body language in video conferencing played an important role in the outcome of negotiations.
It improves your emotional intelligence. Your ability to effectively communicate your emotions and ideas is central to your emotional intelligence. People whose body language is negative have a destructive, contagious effect on those around them. Working to improve your body language has a profound effect on your EQ and you can measure those improvements with an emotional intelligence test.
Bringing It All Together
We often think of body language as the result of our attitude or how we feel. This is true, but psychologists have also shown that the reverse is true: changing your body language changes your attitude.
