Academic study suggests devices cannot differentiate between someone being overworked and being excited
They are supposed to monitor you throughout the working day and help make sure that life is not getting on top of you.
But a study has concluded that smartwatches cannot accurately measure your stress levels – and may think you are overworked when really you are just excited.
Researchers found almost no relationship between the stress levels reported by the smartwatch and the levels that participants said they experienced. However, recorded fatigue levels had a very slight association with the smartwatch data, while sleep had a stronger correlation.
Eiko Fried, an author of the study, said the correlation between the smartwatch and self-reported stress scores was “basically zero”.
