Wearable technology sleep sensors may not be as accurate as you think
A new study has revealed that many gadgets overestimate the number of hours wearers are sleeping.
As 2016 gets off to a new start and people begin their resolutions, many are using wearable technology to help them to try to get in shape, improve their fitness, lose weight, or achieve better overall health.
As a part of that, many users of wearables have been tracking their sleeping habits through their gadgets.
That said, a new study has now suggested that the promises made by wearable technology to help you to measure the length of a night’s sleep may not be accurate at all. The research showed that devices, which primarily included Fitbit and Jawbone gadgets, were overestimating the number of hours of sleep people were actually receiving. This study was conducted as a review of 22 other published studies that used these device for this purpose.
Many of the articles found the wearable technology could accurately complete their measuring functions.
Sleep wasn’t the only issue that was pointed out in this research. Both the Fitbit and Jawbone devices were shown in many of the articles to be able to complete the counting tasks in a lab as well as in the field. However, there was only a single study that had actually looked into the capability for Fitbit to measure distance. What it found was that Fitbit was programmed to overestimate a slower speed and would underestimate a faster speed. This could cause the results to be skewed.
The accelerometry was a central component for measuring the wearer’s physical activity. The study indicated a strong link between slower and faster motion and inaccurate results. Moreover, when conducting an assessment of several comparative analyses of the wearable tech devices, the researchers determined that the wearables from both brands were underestimating calorie levels while they were overestimating the number of hours a user was sleeping.
The outcome of the new study was, therefore, that while these devices are relatively precise when it came to functioning as a pedometer that would count steps, they may not be nearly as accurate in their ability to calculate the number of calories that are burned or the number of hours of sleep an individual may be receiving.
