Classification: CPC G | IPC G

Claim 4:
5. A user recognition apparatus using a 2D EMG spectrogram image, comprising:
an acquisition part configured to acquire a one-dimensional EMG signal for a user; and
a controller configured to convert the acquired one-dimensional EMG signal to a 2D EMG spectrogram image including a temporal feature and a frequency feature, and recognize the user based on the 2D EMG spectrogram image,
wherein the controller divides the one-dimensional EMG signal into repetitive cycles for one motion of the user, separates the divided one-dimensional EMG signal for each of at least one muscle used for one motion of the user, and combines the one-dimensional EMG signal separated for each of the at least one muscle in a time domain.
