Vibration Influences Haptic Perception of Surface Compliance During Walking
A higher value means more compliant (less stiff). “X” labels the no-vibration stimulus. Others are labeled with a 3-letter string encoding waveform, envelope, and amplitude level (0, 1 = Linear amplitude 0.5, 1.0). Error bars = 1 standard error of the mean (SEM). All vibrating stimuli were significantly more compliant than the no-vibration stimulus.
