Fig. 6

Representative plots from one subject of the estimation of the mean and variance of two features (slope sign changes and waveform length) from one channel when the wrist is in a neutral position and when the wrist is flexed. a No hand motion class (b) Hand open class (c) Chuck grip class (d) Key Grip class. Each dot within an ellipse represents the mean of the features. Each ellipse is constructed using the mean and the two standard deviation vectors
