Why The NY Times Thinks Activity Trackers Are Truly Limited
The newspaper's Wired Well section looks into what trackers can and can't do.
In a recent post, the NY Times' Wired Well section lists down some of the capabilities and limitations of activity trackers today and presents the way these devices track specific movements with corresponding activity charts.
Health and activity trackers all have an accelerometer to record changes in movements relative to the device. It tracks up-and-down, side-to-side, and front-to-back motions.
Wristband trackers use accelerometers to measure motion and use proprietary algorithms to analyze motion and convert that into data that the wearer can understand like calories burned and number of steps taken.
