A team of researchers at the University of North Carolina at Chapel Hill and the University of Maryland at College Park has recently developed a new deep learning model that can identify people's emotions based on their walking styles.
Their approach, outlined in a paper pre-published on arXiv, works by extracting an individual's gait from an RGB video of him/her walking, then analyzing it and classifying it as one of four emotions: happy, sad, angry or neutral.
"Emotions play a significant role in our lives, defining our experiences, and shaping how we view the world and interact with other humans," Tanmay Randhavane, one of the primary researchers and a graduate student at UNC, told TechXplore.
"Perceiving the emotions of other people helps us understand their behavior and decide our actions toward them. For example, people communicate very differently with someone they perceive to be angry and hostile than they do with someone they perceive to be calm and contented."
Most existing emotion recognition and identification tools work by analyzing facial expressions or voice recordings.
However, past studies suggest that body language (e.g., posture, movements, etc.) can also say a lot about how someone is feeling.
Inspired by these observations, the researchers set out to develop a tool that can automatically identify the perceived emotion of individuals based on their walking style.
"The main advantage of our perceived emotion recognition approach is that it combines two different techniques," Randhavane said.
"In addition to using deep learning, our approach also leverages the findings of psychological studies. A combination of both these techniques gives us an advantage over the other methods."
The approach first extracts a person's walking gait from an RGB video of them walking, representing it as a series of 3-D poses. Subsequently, the researchers used a long short-term memory (LSTM) recurrent neural network and a random forest (RF) classifier to analyze these poses and identify the most prominent emotion felt by the person in the video, choosing between happiness, sadness, anger or neutral.
The LSTM is initially trained on a series of deep features, but these are later combined with affective features computed from the gaits using posture and movement cues. All of these features are ultimately classified using the RF classifier.
Randhavane and his colleagues carried out a series of preliminary tests on a dataset containing videos of people walking and found that their model could identify the perceived emotions of individuals with 80 percent accuracy. In addition, their approach led to an improvement of approximately 14 percent over other perceived emotion recognition methods that focus on people's walking style.
"Though we do not make any claims about the actual emotions a person is experiencing, our approach can provide an estimate of the perceived emotion of that walking style," Aniket Bera, a Research Professor in the Computer Science department, supervising the research, told TechXplore.
"There are many applications for this research, ranging from better human perception for robots and autonomous vehicles to improved surveillance to creating more engaging experiences in augmented and virtual reality."
Along with Tanmay Randhavane and Aniket Bera, the research team behind this study includes Dinesh Manocha and Uttaran Bhattacharya at the University of Maryland at College Park, as well as Kurt Gray and Kyra Kapsaskis from the psychology department of the University of North Carolina at Chapel Hill.
To train their deep learning model, the researchers have also compiled a new dataset called Emotion Walk (EWalk), which contains videos of individuals walking in both indoor and outdoor settings labeled with perceived emotions.
In the future, this dataset could be used by other teams to develop and train new emotion recognition tools designed to analyze movement, posture, and/or gait.
"Our research is at a very primitive stage," Bera said.
"We want to explore different aspects of the body language and look at more cues such as facial expressions, speech, vocal patterns, etc., and use a multi-modal approach to combine all these cues with gaits.
Currently, we assume that the walking motion is natural and does not involve any accessories (e.g., suitcase, mobile phones, etc.).
As part of future work, we would like to collect more data and train our deep-learning model better. We will also attempt to extend our methodology to consider more activities such as running, gesturing, etc."
According to Bera, perceived emotion recognition tools could soon help to develop robots with more advanced navigation, planning, and interaction skills.
In addition, models such as theirs could be used to detect anomalous behaviors or walking patterns from videos or CCTV footage, for instance identifying individuals who are at risk of suicide and alerting authorities or healthcare providers.
Their model could also be applied in the VFX and animation industry, where it could assist designers and animators in creating virtual characters that effectively express particular emotions.

Look. Either she walks like an Egyptian, or she has to have swagger-jagger.
I see you spam your own threads too.
What shoes?
You're a real weirdo. What kind of a guy is so fascinated with, of all things, women's soccer?? And don't say President Trump. He obviously was just doing what he thought he had to do in rooting for the team.
And speaking of spamming one's own thread, how about those 30 or so posts of yours on the women's soccer thread that you posted, each of them sent to yourself.
I doubt there's more than 3 or 4 guys in our entire membership (of thousands) who are even remotely interested in women's soccer. It's just plain weird, for a guy.
You're a real weirdo. What kind of a guy is so fascinated with, of all things, women's soccer?? And don't say President Trump. He obviously was just doing what he thought he had to do in rooting for the team.Says the real weirdo grown man posting toy car threads - LoL!
Women's soccer has many male fans:
BBC - A record-breaking 28.1m people watched BBC coverage of the Women's World Cup on television and online. That is 47% of the UK population,
... There was a gender split of 62% male, 38% female,
And yes including President Trump who made it clear he really enjoys watching women's soccer. Says a lot about you that you cheapen President Trump as a political whore looking to score points.
Here real weirdo, since it bothers you so much that President Trump "loves watching women's soccer":
Trump, who has suggested NFL players who protest during the anthem shouldn't be in the country, disagreed with Rapinoe's actions but offered praise for the women's national team.My posts were nothing like spam. Posting updates to myself is posting to All."I love watching women's soccer," he said in the Oval Office. "They’re really talented."
Btw ETL, I thought it was weird that you posted a thread about studying walks and commented yourself with spam about silly and robotic walks but not an appealing female walk. I had to do that for you. You are welcome. Sheesh talk about a real weirdo - LoL!
You are definitely not the one to talk about what men should like.
I will go on record saying Trump was giving the bitch credit to try to be politically smart
I don’t care about any soccer
I think it all sux
In Berlin you do as a Berliner you watch it just as I did in Rio
But it’s borimg and Rapinoe is a disgusting narcissistic butch trying to score a resistance endorsement
On this site that doesn’t play well
I will go on record saying Trump was giving the bitch credit to try to be politically smartThen you are on record saying that President Trump is a cheap political whore.
I agree with President Trump that Rapinoe should not protest the National Anthem.
Unless of course he is just saying that too as a political whore, that you make him out to be.
How do we know where President Trump stands on anything?
Thanks for contributing to this site, Wardaddy.
Good grief. How ridiculously stupid. But then, coming from an idiot like you, not at all surprising.
As for "toy cars", on rare occasions I post stuff on vintage toy cars, trains, and other related things, because it brings back nice memories for many if not most of the normal people on the site. But far more frequently, as many here I'm sure know, I post threads on real cars: vintage classics, old-school customs, dragsters, American muscle cars, famous TV and movie cars, etc. Stuff I doubt you have any interest at all in.
So why don't you go watch some reruns of your Kaepernick-admiring, anti-American, lesbo, hero running around kicking a soccer ball. It seems it's all you live for. Friggin weirdo.
Using ex-muggers is actually a great idea,imho.
"Btw ETL, I thought it was weird that you posted a thread about studying walks and commented yourself with spam about silly and robotic walks but not an appealing female walk. I had to do that for you."Name calling is no defense for posting silly walks while failing to post an appealing women's walk. Especially when flaming about what men should like. Just to let you know.Good grief. How ridiculously stupid. But then, coming from an idiot like you, not at all surprising.
I have no reply to your defense of posting toy cars threads. Boring.
So why don't you go watch some reruns of your Kaepernick-admiring, anti-American, lesbo, hero running around kicking a soccer ball. It seems it's all you live for. Friggin weirdo.Rapinoe is one player on the USWNT. Not even my favorite. I occasionally post about USWNT games when I am able to watch them and covered then during the World Cup and will happily continue to do so. Funny you think that is all I live for. I'll make a list of weirdo Fanboys I have and put you at the top of it.
All the walks I study are silly!
Go away you friggin a-hole.
That’s you angry guy.
All your buttons got pushed and all I did was post a sexy women’s walk - LoL!
"Huey Percy Newton (February 17, 1942 – August 22, 1989) was an African-American political activist and revolutionary who, along with Bobby Seale, co-founded the Black Panther Party in 1966. He continued to pursue an education, eventually earning a Ph.D. in social philosophy.[1][2] In 1989 he was shot and killed in Oakland, California. ..."
"As a student at Merritt College in Oakland, Newton became involved in politics in the Bay Area. He joined the Afro-American Association (AAA), became a prominent member of Phi Beta Sigma fraternity, Beta Tau chapter; and played a role in getting the first African-American history course adopted as part of the college's curriculum.
He read the works of Karl Marx, Vladimir Lenin, Frantz Fanon, Malcolm X, Mao Zedong, Émile Durkheim, and Che Guevara.
During his time at Merritt College, he met Bobby Seale, and the two organized the Black Panther Party for Self Defense in October 1966.[3]"

From the article: REVOLUTIONARY HEROES
"On May 1st, May Day [1969], the day of the gigantic Free Huey [Newton] rally, two of Alioto's top executioners vamped on the brothers from the Brown Community who were attending to their own affairs. These brothers, who are endowed with the revolutionary spirit of the Black Panther Party defended themselves from the racist pig gestapo [the police].
Pig Joseph Brodnik received his just reward with a big hole in the chest. Pig Paul McGoran got his in the mouth which was not quite enough to off him.
The revolutionary brothers escaped the huge swarm of pigs with dogs, mace, tanks and helicopters, proving once again that "the spirit of the people is greater than the man's technology."
To these brothers the revolutionary people of racist America want to say, by your revolutionary deed you are heroes, and that you are always welcome to our camp."

Hey Weirdo, when I care what someone who posts a walk study thread and then posts silly and robotic spam to himself while failing to post a sexy woman's walk (again you are welcome for my post) - thinks about me then I will let you know.

Rapinoe says it is important for white and black athletes to stand together
On Sunday, Rapinoe said her gesture was a nod towards Kaepernick.
“It was very intentional,” Rapinoe told American Soccer Now after the game.
“It was a little nod to Kaepernick and everything that he’s standing for right now.
I think it’s actually pretty disgusting the way he was treated and the way that a lot of the media has covered it and made it about something that it absolutely isn’t.

Donald Trump Jr. had a scathing critique of the athletic company Nike after it decided to pull a sneaker bearing a flag used during the American Revolution.
Instead of using that older version of the American flag, Trump Jr. suggested Nike should unveil a communist-style shoe looking similar to the hammer-and-sickle logo of the former Soviet Union.
"If the Betsy Ross Flag, the flag of the American Revolution, is too offensive for Nike to commemorate The 4th of July maybe Nike should go with this... seems to be more in line with their views," Trump Jr. tweeted on Wednesday.
His attack came as Nike faced mounting criticism over its decision to halt the release of a shoe that had the Betsy Ross flag because it could "unintentionally offend" people.

Amidst her World Cup celebration in the Big Apple, Megan Rapinoe let the curse word fly on live TV!
Megan and the rest of the United States Women’s National Team were in town to celebrate their FIFA World Cup victory.
After the parade made its way up the “Canyon of Heroes” to the steps of City Hall, Megan was given the mic.
After she gave a rousing speech that encouraged everyone to “love each other” more and hate each other less, she gave a little love to the Big Apple.
“New York City, you’re the mother*cking best!”
The vulgarity won over the hearts of many fans watching and many hoped that she would run for president.
