1. A method for recognizing sign language using an electromyogram sensor and a gyro sensor, the method comprising the steps of: (a) receiving a gyro measurement signal and an electromyogram measurement signal from the gyro sensor and the electromyogram sensor which are attached to the body of a subject; (b) determining to which of groups clustered with similar fingerspelling motions the gyro measurement signal belongs; (c) acquiring a Gaussian model for the electromyogram measurement signal; and (d) comparing the acquired Gaussian model with Gaussian candidate models for candidate fingerspelling motions which belong to the group determined in step (b), and recognizing the candidate fingerspelling motion corresponding to the Gaussian candidate model that is most similar to the acquired Gaussian model as the fingerspelling motion of the subject.
