Researchers have developed two new methods to improve inertial odometry, a technique for tracking motion using only inertial measurement units (IMUs). The first method, MARIO, integrates a learned pose prior based on human kinematics and fuses data from auxiliary sensors like magnetometers and barometers to reduce positional drift by up to 42%. The second method, FDIO, decomposes IMU signals into low and high frequency components, using a Mamba module for long-range motion and convolutional modules for local dynamics, achieving significant error reductions compared to existing baselines.
