Successful trials in detecting steps. In the detection of the step height, detected data are averaged with 100 trials.

Real step height (cm)	Successful detection rate	Mean value (cm)	Max. value (cm)	Min. value (cm)	Variance (cm)
1.30	100/100	1.37	1.47	1.17	0.0017
−1.30	100/100	−1.21	−1.11	−1.33	0.0022
