Experimental protocol. a At home, subjects performed the following set of physical activities in the order shown. b In the lab, subjects performed the physical activities in the displayed sequence in order to record every pair of transitions between activities. c Data from a tri-axial accelerometer was collected while performing these activities. d Data processing. A series of features were extracted from 10 s clips of data, and supervised machine learning was used to train an activity recognition classifier
