A review conducted by MIT Technology has revealed that Microsoft Band is much accurate when compared to the Apple Watch while measuring a human’s heart rate. The review was undertaken by a senior editor at MIT Rachel Metz, who spent a substantial amount of time with the two, while also wearing a Polar H7 Bluetooth chest. According to her, Polar H7 is supposed to be one of the most accurate consumer devices for measuring heart rate, so it was laying the benchmark standards for the review.
After several days of data was collected, Metz compared the results of Microsoft Band and Apple Watch, both of which use optical sensors to measure a person’s heart rate, and compared them with the results of the Polar H7 chest strap which uses electrical signals within the skin to detect heart beats.
The results found seem rather baffling, as Metz data found that Microsoft Band’s measured heart rate activity was much in tune with the Bluetooth chest strap than the Apple Watch. The Microsoft Band was usually within a beat or two off, but sometimes it could go as high as 13 beats off. While the Apple Watch was surprisingly way off as much as 77 beats per minute compared to the chest strap, which is quite shocking.
“The experience was a far cry from the vision of these devices as digital sages drawing deep, accurate insights from the data they collect, helping doctors diagnose ailments, and eventually, perhaps, even predicting health problems or detecting them before they become serious. These are hard goals to achieve, for several reasons,” reads the research page.
The research further mentions that the wrist is not a great spot to take accurate measurements as everybody’s body is different.
“You can make millions of smart watches that are identical, but you have millions of people who are not identical. It’s really hard to find something that’s robust across all these people,” says Chris Harrison, an assistant professor of human-computer interaction who leads the Future Interfaces Group at Carnegie Mellon University.
We are witnessing times where fitness trackers and smartwatches are substantially booming; every established manufacturer has its own version fitness trackers/smartwatches these days – from affordable ones to the high-end smartwatches. But we ask the question, are they are any good and can they really perform the way they’re supposed to, or are they just a marketing gimmick in the name of fitness?
