Not just your employer or spouse, even computers programmed to monitor people’s body language can tell whether they are bored or not, says a study.
Body-language expert Dr Harry Witchel, from University of Sussex, found that by measuring a person’s movements as they use a computer, it is possible to judge their level of interest. This can be done by monitoring whether they display the tiny movements that people usually constantly exhibit — known as non-instrumental movements.
According to Dr Witchel, if someone is absorbed in what they are watching or doing, there is a decrease in these involuntary movements. “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,” Dr Witchel explained.
The study — published in the journal Frontiers in Psychology — could have a significant impact on the development of artificial intelligence (AI). “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,” the author added.
In the study, 27 participants were faced with three-minute computer sessions that ranged from fascinating games to tedious readings from the European Union (EU) banking regulations. At the same time, video motion-tracking technology was used to measure their movements.
For two comparable reading tasks, the one that was most engaging resulted in a 42 per cent reduction in non-instrumental movement.
“The findings can also help us create more empathetic companion robots — which may sound very ‘Sci-Fi’, but are becoming a realistic possibility within our lifetimes,” Dr Witchel noted.
