Comparison with foot-mounted PDR.
| Our Approach | Foot-mounted method (L. Ojeda 2007) | |
|---|---|---|
| Hardware | 3-axis accelerometer & gyroscope | 6-DoF inertial sensor (accelerometer + Gyro + Magnetic) |
| Sample Rate | 25Hz | 200Hz |
| Placement | Waist | Foot |
| ZUPT | Use the concept of SHM | Calculate the angular velocity to detect zero velocity |
| Accuracy | 98.25±1.29% (total distance) | >98% (total distance) >99% (coordinate) |
