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.

Wearable Technology - SleepSleep 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.

QR codes help students and teacher boost Nature Center experience

In Sterling Heights, Michigan, a teacher and her students have worked together to enhance education.

Sterling Heights, Michigan teacher, Christine Kincaid-Dewey, has worked with her students from the Macomb Mathematics, Science and Technology Center (MMSTC) in order to use QR codes to help to enhance the experience visitors receive when they head to the Nature Center in the city.

As a result of their efforts, the teacher and students have been recognized by the city as “Nice Neighbors”.

The “Nice Neighbor” award was presented to the group by Recreation Supervisor for the city, Mark DiSanto. Following the presentation, DiSanto explained that “Mrs. Kincaid-Dewey and her students undertook a project to bring Quick Response Code technology to the Nature Center’s many exhibits.” The aim of the project was to allow visitors to scan QR codes while at the Nature Center so they can learn more about the exhibits than would be possible to add to display signage.

The QR codes were used to automatically direct smartphone users to the information specific to each exhibit.

QR Codes Help Students & TeachersMobile device users can scan the QRcodes with any free reader app. These scanner applications are available at virtually every app store for devices on nearly every platform. Upon scanning the barcodes, the device automatically directs the user to a URL containing the relevant information.

DiSanto said that “Mrs. Kincaid-Dewey and her MMSTC students developed unique QR codes that provide unique and interesting facts about the exhibits being viewed,” and went on to add that “This information makes the exhibits come alive in a way that is simply not possible through traditional means.”

Another advantage to using quick response codes is that it is very easy to digitally update the information without having to change the barcode. This process is much more challenging when it comes to having to alter printed signage at an exhibit.

Kincaid-Dewey explained that her inspiration for the project she completed with her students was from previous visits she had made to the Nature Center with the MMSTC Ecology Club and their interest in giving back to it in a helpful and meaningful way.
