Non-optical wearable sensors, such as magnetic and inertial measuring units (MIMU), are becoming popular in various fields: sports, medical, industrial - due to their ease of use and relative availability. We propose an algorithm for calibrating wearable sensors based on the rotation algebra. A system for visualizing human kinematics, which is reconstructed from MIMUs' data, is presented.
