Classification error of parallel classifiers when trained with and without 2-DOF motion class data. Error is partitioned into error for 1-DOF intended motions and 2-DOF intended motions. Training with only 1-DOF motion class data resulted in significant increases in error for both intramuscular and surface signal sources. Results are an average of four subjects. * p<0.05, ** p<0.01. Error bars show +/− 1 SEM. (IM = intramuscular)
