Fresh off the Vegas-style hypefest that is the Consumer Electronics Show, fitness wearables darling Fitbit is already in hot water. Numerous customers, furious at the inaccuracies of Fitbit’s devices, filed a national class-action lawsuit on January 5.
“Plaintiffs and many consumers like them have experienced—and testing confirms—that the [Fitbit] PurePulse Trackers consistently mis-record heart rates by a very significant margin, particularly during exercise,” the lawsuit alleges. “Far from ‘counting every beat,’ the PurePulse Trackers do not and cannot consistently and accurately record wearers’ heart rates during the intense physical activity for which Fitbit expressly markets them.”
Fitbit, predictably, takes issue with the statements in the lawsuit. “Fitbit stands behind our heart rate technology and strongly disagrees with the statements made in the complaint and plans to vigorously defend the lawsuit,” a Fitbit spokesperson says – but then issues an important caveat: “But it’s also important to note that Fitbit trackers … are not intended to be scientific or medical devices.”
Fitbit is attracting most of the negative publicity surrounding the accuracy of wearables, but in fact there’s concern broadly about just how accurate any of the fitness wearables on the market actually are. “Cycling, not great,” says Ray Browning, a professor at Colorado State University who directs the Physical Activity Energetics/Mechanics Laboratory. “Elliptical training, not great. Yoga, terrible. There are some pretty significant limitations.”
Other academics have also weighed in on the challenges delivering accurate results various wearable fitness devices face. “You can make millions of smart watches that are identical, but you have millions of people who are not identical,” says Chris Harrison, an assistant professor of Human-Computer Interaction who leads the Future Interfaces Group at Carnegie Mellon University. “It’s really hard to find something that’s robust across all these people.”
From Accuracy to Trust
On the reasonable assumption that fitness wearables vendors realize their devices are not particularly accurate, the question then becomes whether consumers can trust the devices to suit a particular purpose. If a device helps you with your exercise regimen, then does it matter whether it’s accurate?
