Biobank Accelerometer Analysis Tool
A tool for large scale analysis of wearable sensor data to extract health-relevant metrics on activity levels, step counts, circadian rhythm, sedentary time, and more. The tool has been used in studies involving the UK Biobank accelerometer dataset as well as the China Kadoorie Biobank accelerometer dataset, enabling fine-grained analysis of 24h physical behaviour patterns at the population scale.
