Computers Can Detect Boredom in Body Language

New software and video tracking can tell whether a person is bored or interested in what they see on the screen. Experts believe this new capability to read body language and detect engagement has important implications for online education.

Body-language expert Dr. Harry Witchel of Brighton and Sussex Medical School (BSMS) led the study. His research determined that by measuring a person’s movements as they use a computer, it is possible to judge their level of interest.

This occurs by monitoring whether they display the tiny movements that people usually constantly exhibit, known as non-instrumental movements. If someone is absorbed in what they are watching or doing — what Dr Witchel calls “rapt engagement” — there is a decrease in these involuntary movements.

Witchel said, “Our study showed that when someone is really highly engaged in what they’re doing, they suppress these tiny involuntary movements. It’s the same as when a small child, who is normally constantly on the go, stares gaping at cartoons on the television without moving a muscle.”

The discovery could have a significant impact on the development of artificial intelligence.

Future applications could include the creation of online tutoring programs that adapt to a person’s level of interest, in order to re-engage them if they are showing signs of boredom. It could even help in the development of companion robots, which would be better able to estimate a person’s state of mind.

Researchers believe the finding also has implications for experienced designers such as movie directors or game makers. They believe the technology could provide complementary moment-by-moment reading of whether the events on the screen are interesting.

While viewers can be asked subjectively what they liked or disliked, a non-verbal technology would be able to detect emotions or mental states that people either forget or prefer not to mention.

“Being able to ‘read’ a person’s interest in a computer program could bring real benefits to future digital learning, making it a much more two-way process,” Witchel said.

“Further ahead it could help us create more empathetic companion robots, which may sound very ‘sci fi’ but are becoming a realistic possibility within our lifetimes.”

In the study, 27 participants faced a range of three-minute stimuli on a computer, from fascinating games to tedious readings from EU banking regulation, while using a handheld trackball to minimize instrumental movements, such as moving the mouse.

Their movements were quantified over the three minutes using video motion tracking. In two comparable reading tasks, the more engaging reading resulted in a significant reduction (42 percent) of non-instrumental movement.
