title: [A method for analyzing of balanced capacity based on fast Fourier transform].
abstract: Evaluating the balanced capacity effectively is convenient to take some appropriate therapy measures to avoid some falling accidents. In the paper, we collect pressure data from the sole of feet at eight postures of standing and get the track of the man's center of gravity. Then we process these data with fast Fourier transform(FFT), after that, we can see the relation between amplitude and frequency of movement, and know very well shaking degree of standing, then get a technique data of evaluating man's balanced capacity objectively.
