Separating movement and gravity components in an acceleration signal and implications for the assessment of human daily physical activity.

Separating movement and gravity components in an acceleration signal and implications for the assessment of human daily physical activity.

<h4>Introduction</h4>Human body acceleration is often used as an indicator of daily physical activity in epidemiological research. Raw acceleration signals contain three basic components: movement, gravity, and noise. Separation of these becomes increasingly difficult during rotational m...
