When Robots Feel Our Pain: Rosalind Picard on ‘Emotional Intelligence’ in a Brave New World

AI pioneer to explain empathetic computers in Wall Exchange lecture.

By Malone Mullin 10 Oct 2018 | TheTyee.ca

Malone Mullin studied journalism at the University of British Columbia and is now a journalist with the CBC.

Rosalind Picard was just a fledgling engineer in a young industry, right around the time Microsoft introduced Windows 95 and only two years after the World Wide Web entered mainstream consciousness, when she became an accidental pioneer.

Picard, who will speak in Vancouver Nov. 5, is now the Massachusetts Institute of Technology professor and director of the Affective Computing Research Group.

But back then she was a bright-eyed tinkerer designing algorithms and search engines for the university’s Media Lab who happened to learn about a region deep in the brain that helps humans decide what warrants their attention.

The limbic system, sometimes called the “old mammalian” brain, points out priorities so that evolutionarily newer regions, such as the visual or linguistic system, can take over and make sense of incoming data.

The flexibility of that mechanism struck Picard as a missing element in her own work, an undiscovered way to make machines smarter. The future of engineering, she gambled, lay in modelling computers after the brain.

“A camera, for example, equally weights all information,” Picard explained. To a lens, she noted, a speck on the wall is just as important as a glint in someone’s eye.

A human can control the camera. But what good is a futuristic robot if it doesn’t know when to make eye contact with the human issuing an order? How can artificial intelligence help a camera interpret an image as a person would?

Picard realized no one had a way to engineer emotional intelligence in a computer, to code for empathy or intuition in a piece of software. So in 1997, the year before she was up for tenure, she wrote a book called Affective Computing.

Over 20 years later, Picard is still at the forefront of a field her book helped to launch, inventing intelligent machines with the capacity to understand and interpret human emotion – and ultimately even convey it.

“It’s kind of embarrassing,” she joked. “I started as a woman in science who didn’t want anything to do with emotion. And here I am today.”

Back when Picard was writing her first book, the chief roadblock was simply finding a method to define human feeling in an objective way, to quantify emotion so that feelings of anxiety or joy could be translated to code. No one had an answer to the challenge.

“I’m not sure I do either,” Picard laughed, pointing out the difficulties of taking an abstract concept like “shame” – one that may have different expressions across cultures – and writing a program to recognize it based on visual cues like body language.

“We can’t measure your experience exactly,” Picard explained. “But computers can collect data, and we have the ability to interpret that data. So when I see a smile, I think you’re happy. But the more data we have, with regards to dynamics and context, there could be different meanings to that smile.”

For instance, a mother may be putting on a brave face for her kids after the death of a family member, but the tone of her voice could hint at underlying stress and sadness. An emotionally intelligent device would recognize that distinction, paired with the fact of the death, and respond in a subdued or apologetic way.

“The goal is to honour people’s feelings, to better integrate this technology into our lives,” Picard said.

Her recent projects aim to do just that: allow computers to read and analyze nuanced emotional signals to offer better services, from marketing to medicine.

Picard’s company Empatica makes a bracelet for people with epilepsy that warns caregivers of a coming seizure; it also collects data about patients’ mood and activity levels to help them figure out what behaviours are more likely to precipitate an episode.

Her other company, Affectiva, interprets facial expressions – to what extent brows or cheeks are raised, whether the head is tilted forward, the exact movement of the lips – to tell advertisers, researchers and even mothers caring for autistic children how a subject might be feeling at any particular moment.

Picard receives criticism for her research. Some critics worry about the practical implications, like job loss resulting from widespread automation.

But Picard said “there’s a deeper fear” that “technology is going to rapidly exceed us, and we’ll be reduced to helpful pets.”

Picard waves off that concern as the stuff of science fiction.

“We don’t like the idea of building AI to make us obsolete. We want to extend and amplify human intelligence, help us be healthier. We don’t want to write ourselves out of the future,” she said.

“That’s the theme in so many AI movies, but it’s not possible. AI can’t grab control without us, the engineers, giving them that control.”

Her personal worry hinges not on an AI-driven apocalypse, but on navigating the technology’s possibilities. “There’s a hundred interesting, cool things to invent every day and we have to pick just a few,” Picard said.

“I find myself asking, will my grandchildren be proud? You start to think about everyone, not just your CV or media coverage. You start to think about the future you’re making for your kids. You have to do some soul-searching. But it’s not going to be a dystopic future unless we build it that way.”

Picard is in Vancouver on Nov. 5 for the Wall Exchange, a free lecture series organized by the Peter Wall Institute for Advanced Studies. For more information and to reserve free tickets go here.  [Tyee]
