A Step Length Estimation Model of Coefficient Self-Determined Based on Peak-Valley Detection

Table 3

The error of the peak-valley detection and peak detection on 500 steps of free walking.

	Volunteer	Gender	True steps	Peak-valley detection		Peak detection
				Estimated	Error	Estimated	Error
Two of the ten volunteers	Vol 1	Male	500	500	0	507	1.4%
	Vol 2	Female	500	499	0.2%	509	1.8%
Additional five volunteers	Tester 1	Male	500	500	0	507	1.4%
	Tester 2	Male	500	500	0	505	1.0%
	Tester 3	Male	500	501	0.2%	510	2.0%
	Tester 4	Male	500	498	0.4%	506	1.2%
	Tester 5	Female	500	496	0.8%	505	1.0%
