GOQii Tracker works on 3-axis accelerometer to understand your motions. An accelerometer is a device that turns movement (acceleration) of a body into digital measurements (data) when attached to the body. GOQii trackers have a finely tuned algorithm for step counting. The algorithm is designed to look for motion patterns most indicative of people walking and running. One condition for a motion pattern to be recognized as a step is the motion must be large enough.
When working at a desk, cooking, or doing other arm movements, the tracker can pick up some extra steps if it thinks you are walking. Many of these situations—such as working or cooking—do include a few steps in-between stationary periods so the tracker tries to give you credit for those steps. For the vast majority of customers, the amount of stray steps accumulated is negligible when compared to the entire day.
The GOQii Core determines the steps taken and active time simultaneously. This information along with your height, gender, age, and weight is used to quantify distance traveled and the amount of calories burned each day.
