Double support detection: (a) shows double support when left leg is in front, (b) shows double support when right leg is in front. Red and blue markers indicate a location of body and leg COMs. (c) demonstrates a clear gap in COM𝑦 value between left and right leg double support. 𝑥 axis denotes time in frames, and 𝑦 axis denotes 𝑦 coordinate of COM.
