Fig. 1

Example of identification of False Positive (FP), False Negative (FN), True Positive (TP) and True Negative (TN) for the Gait Sequence Detection (GSD) algorithms, of each window (0.1 s). Events classified from the comparison of each individual window between the INDIP reference system (RS) and the single wearable device (WD) for the detection of gait sequences. Each window of the WD and RS outputs are depicted as a rectangle, where white rectangles represent windows of non-gait sequences, and grey rectangles denote windows of a detected gait sequence
