%?WALKER??Human?gait.
%?This?model?developed?by?Nikolaus?Troje?is?a?five-term?Fourier?series
%?with?vector-valued?coefficients?that?are?the?principal?components?for
%?data?obtained?in?motion?capture?experiments?involving?subjects?wearing
%?reflective?markers?walking?on?a?treadmill.??The?components?which?are
%?also?known?as?“postures“?or?“eigenwalkers“?correspond?to?the?static
%?position?forward?motion?sideways?sway?and?two?hopping/bouncing
%?movements?that?differ?in?the?phase?relationship?between?the?upper?and
%?lower?portions?of?the?body.??The?postures?are?also?classified?by?gender.
%?Sliders?allow?you?to?vary?the?amount?that?each?component?contributes?to
%?the?overall?motion.??A?slider?setting?greater?than?1.0?overemphasizes
%?the?characteristic.??Can?you?see?whether?positive?values?of?the?gender
%?coefficient?correspond?to?male?or?female?subjects?
