1
Q
What does an IMU measure?
A
It measures acceleration, angular velocity, and sometimes magnetic fields using accelerometers, gyroscopes, and magnetometers.
2
Q
Why is sensor placement and coupling important?
A
Poor placement or soft tissue artefact can distort data by creating a mismatch between sensor and skeletal movement.
3
Q
What’s the purpose of filtering in wearable data?
A
Filters like Butterworth remove noise and drift, improving the accuracy of biomechanical signals
