Claim 0:
1. A user recognition method using a two-dimensional (2D) electromyogram (EMG) spectrogram image, comprising:
(a) acquiring a one-dimensional EMG signal for a user;
(b) converting the acquired one-dimensional EMG signal to a 2D EMG spectrogram image including a temporal feature and a frequency feature; and
(c) recognizing the user based on the 2D EMG spectrogram,
wherein the operation (b) includes: dividing the one-dimensional EMG signal into repetitive cycles for one motion of the user; separating the divided one-dimensional EMG signal for each of at least one muscle used for one motion of the user; and combining the one-dimensional EMG signal separated for each of the at least one muscle in a time domain.
