Optimization of Semiautomated Calibration Algorithm of Multichannel Electrotactile Feedback for Myoelectric Hand Prosthesis

Figure 2

Calibration GUI implemented in MATLAB. (a) STOP button used in phase 1 of the standard calibration procedure for stopping the increase in stimulation intensity when a satisfying sensation is reached. (b) FAST button for activation of fast scanning sequence of previously selected intensities. (c) FINE-TUNE button used to start the fine-tuning protocol. (d) NEXT button used for transition to the following pad if necessary. (e) “up” and “down” arrows for adjusting the amplitude of the corresponding pad during fine-tuning.
