Fig. 4

Examples of signals from LRFs and an accelerometer taken over 8 s. a Vertical acceleration from wearable accelerometer. Dashed line shows original signals and solid line shows smoothed signal. b Velocity (solid line) and acceleration (dashed line) of left and right feet of a pedestrian from LRFs. c Minimum of acceleration of both feet from LRFs (Eq. 4). d Superimposed signal [acceleration from accelerometer (a) and LRFs (c)]. Signals from same pedestrian shows clear correlation. The vertical axis is adjusted to overlap both signals
