Interpretation of Activity Data Collected with Accelerometers

Interpretation of activity data collected with accelerometers strongly depends on the purpose and health outcome in question and there is no single solution. Instead, a wide range of activity parameters have been presented, e.g. sensor location, sampling rate, acceleration range, pre-processing, analysis algorithm, and selected thresholds define the outcome. This talk overviews some approaches and algorithms for recording physical activity and sedentary behavior, applying data collected with an accelerometer on the wrist and waist in daily life.
