Figure 5From: The impact of the stimulation frequency on closed-loop control with electrotactile feedbackBest tracking trial with electrotactile feedback for a subject with a very good tracking performance. Reference (dotted line) and generated trajectories (continuous line) recorded for the best trial in the electrocutaneous condition 100/100 for a subject with a very good tracking performance. Tracking with electrotactile feedback was very accurate and similar to the tracking with visual feedback (compare to Figure 4a).Back to article page
