Experimental setup for the AR intervention showing a test subject with dysmelia controlling the virtual arm in an AR scene. The left a shows the scene including the system components mounted on the subject and a clothespin case positioned in front of the subject. The subject controlled the virtual hand using EMG signals that were recorded from the residual limb. The middle b reveals the connection and dataflow between the components and the host PC. The panel on the right c shows the view from the subject perspective with the virtual objects (hand, clothespin, and vertical bar) embedded in the real scene
