Fig. 2

A comparison of ATS and Mobility a, c with VeDBA b, d, calculated from two archived tri-axial accelerometry datasets. “High-Activity” (HA) events based on mobility are indicated by black points, which are counted over 75-s periods to calculate ATS (orange line). In c, a gray line indicates mean hourly mobility. VeDBA is colored by cluster, determined by a k-means clustering algorithm with a total of 4 clusters, to visualize different activity levels. ATS and Mobility are not meant to replicate VeDBA, but rather to indicate relative high activity over time
