From: Sensory substitution of elbow proprioception to improve myoelectric control of upper limb prosthesis: experiment on healthy subjects and amputees

Fig. 1

A experimental set-up with a healthy subject. (1) represents the switch allowing the communication between the 3 computers. (2) represents the command of the master PC sending the protocol instructions and evaluating in real time the avatar position. (3) represents the information transferred from the EMGs to move the avatar. (4) represents the computer where Animatlab was running, and the avatar displayed on a screen in front of the subject. (5) represents the commands sent from the master PC to the pi-top computer, receiving the exact arm position and converting it into an activation of the vibrors as the vibro-tactile feedback to the subject. (6) represents the pi-top computer where vibrors were connected. (7) represents the wristlet (also visible in Figure 1. B of 6 vibrors placed on the subject arm. (8) represents the MyoArm band used to collect the muscular activity (EMGs) and sent the data by a Bluetooth procedure to the master PC. B. subject with an amputation at the humeral level wearing equipment composed of the MyoArm band and the vibrors wristlet
