Fig. 4From: Improving internal model strength and performance of prosthetic hands using augmented feedbackPsychophysical test results. a Adaptation rate results showing audio-augmented feedback control strategy enabling higher adaptation to self-generated error than the no-augmented feedback control strategy. b Perception threshold test results showing low JND value when using the audio-augmented controller. c Internal model uncertainty (Pparam) results showing significant reduction in the internal model uncertainty when using the audio-augmented feedback control strategy. Horizontal bars indicate statistical significant difference. NF: No-augmented Feedback. AF: Audio-augmented FeedbackBack to article page
