Figure 6.

Insole-based gait segmentation in different strides: (a) Initial acceleration data from the insole without applying the suggested algorithm (Ay: acceleration in y-axis; Zcr: zero-crossing; TO: toe-off; HS: heel strike); (b) Acceleration data after applying the suggested algorithm (PP: peak-to-peak for strides detection). The Stride is therefore the difference between one green peak and the second next green peak; (c) The total force from the three FSRs (FF: foot flat). The square in solid line represents the moving window in which its length is equal to the locking period; the red circle is the original peak detected and the green circle indicates the correct peak detected after applying our proposed algorithm.
