Classifier performance during grasp selection. (A) Effect of training method and electrode placement on classification error. Analysis performed with 500 ms feature extraction window and 6 grasps available to the classifier. Error bars represent standard error. (B) Effect of window length and number of grasps available to the classifier on classification error. Analysis performed with extrinsic and intrinsic muscle EMG, and with variable wrist positions and dynamic wrist movements included in the training data. Error bars represent standard error. Error bars represent standard error.
