Experimental setup of visual guidance to facilitate the wearable robot use. The participant walked on a treadmill with a unilateral ankle–foot orthosis while being measured for respiratory rate, electromyography (EMG), and pupil diameter. The subject received visual guidance from software with a graphical user interface. The visual guidance presented an animation with an arrow indicating the error between the desired and actual torque. A positive “Up” and a negative “Down” arrow indicated that the user did not provide enough actual dorsiflexion torque and plantarflexion torque, respectively.
