As a wearable device, the Neblina module is capable of tracking the position of a walking/running person both indoors and outdoors along with number of steps and cadence. Using an efficient calibration procedure for magnetometers, a robust calculation of the walking direction is delivered. Our fusion method is capable of detecting the presence of external magnetic disturbances in the environment to make the heading angle calculation robust. A proprietary sensor fusion algorithm is also utilized for orientation estimation using 3-axis accelerometers, gyroscopes and magnetometers, which is guaranteed to deliver higher accuracy without increasing the computational cost compared to previous work.
